Rename the network module to p2p
The `network` module deals with data types and logic related to
internetworking bitcoind nodes, this is commonly referred to as the p2p
layer.

Rename the `network` module to `p2p` and fix all the paths.

Use defensive documentation
Only commit in the docs and error messages to what we _really_ know.

In an attempt to reduce the likelyhood of the code going stale only
commit to what is guaranteed - that we have an error from a module.

This does arguably reduce the amount of context around the error.

Add InvalidSighashTypeError
As we do for `NonStandardSighashErrorType` add an error struct for

Rename non standard sighash error type
Error types conventionally include `Error` as a suffix.

Rename `NonStandardSighashType` to `NonStandardSighashTypeError`.

While we are at it make the inner type private to the crate, there is no
need to leak the inner values type.

Use standard set of derives on all error types
As part of an ongoing effort to make our error types stable and useful
add a stand set of derives to all error types in the library.

    `#[derive(Debug, Clone, PartialEq, Eq)]`

Add `Copy` if possible and the error type does not include
`#[non_exhaustive]`.

If an error type includes `io::Error` it only gets `#[derive(Debug)]`.

Pull request description:

  This PR removes the need to serialize the inner NetworkMessage in the RawNetworkMessage encoding, thus saving memory and reducing allocations.

  To achieve this payload_len and checksum are kept in the RawNetworkMessage and checksum kept in CheckedData, to preserve invariants fields of the struct are made non-public.

Move EncodeSigningDataResult to sighash module
This type was defined in the `transaction` module because it was

Pull request description:

  - Non-standard with respect to stdlib which uses `Path::new` and `PathBuf::new` (on which we based the `Scritp`/`ScriptBuf`)

In order to keep the embedded and schemacs test crates building when we

already has an entry.
- For `hashes/embedded` add `patch` section for `internals`.
- For `hashes/extendend_tests/schemars` add `patch` section for

Use hex_lit::hex in benches
Currently the test `hex` macro is only available when the `test`
compiler configuration option is set but we are using it in benches
code, this works for use because `cargo bench` sets `test` for the
current crate, however it breaks downstream crates.

Fix: #1830

Merge rust-bitcoin/rust-bitcoin#1913: Manually implement Debug on Witness
d45dbef3e7 Manually implement Debug on Witness (Tobin C. Harding)

Pull request description:

  The current derived debug implementation on `Witness` prints the content field as an array of integers. We can do better than this by manually implementing `Debug`.

  With this applied `Witness` is printed as follows: (first line is `{:?}` and the next is `{:#?}`):

  Using `{:?}`:
  ```
  Witness: { indices: 3, indices_start: 8, witnesses: [[0x00], [0x02, 0x03], [0x04, 0x05]] }

Add more rustdocs to WitnessProgram
Add rustdocs to `WitnessProgram` commenting on why we carry the witness
version number around with the witness program. This is mainly a dev
comment but it helps document the invariants so make it a rustdoc
comment.

Move witness types to the script module
From BIP 141:

> A scriptPubKey (or redeemScript as defined in BIP16/P2SH) that
> consists of a 1-byte push opcode (for 0 to 16) followed by a data push
> between 2 and 40 bytes gets a new special meaning. The value of the
> first push is called the "version byte". The following byte vector
> pushed is called the "witness program".

`WitnessVersion` and `WitnessProgram` are scriptPubkey concerns and
scriptPubkey is basically synonymous with address so in one way it makes
sense that these types are in `address` however we are in the process of
overhauling the `Address` (and `AddressInner`) types so lets move the
witness stuff to `script` and put it in individual sub-modules.

This move helps simplify the address error type also.

Note please, there are a bunch of formatting changes in here in the
error type that I cannot explain and could not remove.

Rename Script::empty to Script::new
The `empty` constructor is mis-named for the following reasons:

- Non-uniform with `ScriptBuf::new`
- Non-standard with respect to stdlib which uses `Path::new` and
  `PathBuf::new` (on which we based the `Scritp`/`ScriptBuf`)

Rename the function to `new`, put it at the top of the impl block while
we are at it.

Pull request description:

  We are trying to make error types stable on the way to v1.0

  The current `hashes::Error` is a "general" enum error type with a single variant, better to use a struct and make the error usecase specific.

  Improve the `hashes::Error` by doing:

  - Make it a struct
  - Rename to `FromSliceError`
  - Move it to the crate root (remove `error` module)

  Includes usage in `bitcoin`.

The current `hashes::Error` is a "general" enum error type with a single

- Make it a struct
- Rename to `FromSliceError`
- Move it to the crate root (remove `error` module)

Pull request description:

  Add a checked version of fee_rate * weight.  While I like the trait version of just being able to multiply `feerate * weight`, it's not really very useful imo since a large input feerate could cause an overflow.  Instead of changing the trait in https://github.com/rust-bitcoin/rust-bitcoin/pull/1849 (not idiomatic enough I guess) I added a `checked_weight_mul` method to `FeeRate`.

During the last round of releases (bitcoin 0.30, hashes 0.12) we removed

Martin Habovstiak 6fec1789b9 Fix associated constants of `InputWeightPrediction`
These constants had an error that they had `script_size` set to 0 which
was incorrect because it's not length of the script but serialized size.
Rather than just bumping the value this uses the `from_slice` method
which is less error-prone.

This also deletes a useless test of the constants.

Merge rust-bitcoin/rust-bitcoin#1820: Expose valid (min, max) difficulty transition thresholds
8e6f953aa7 Expose valid (min, max) difficulty transition thresholds (Wilmer Paulino)

Pull request description:

  Once `U256` was made private, we lost the ability to check whether a valid difficulty transition was made in the chain, since `Target` doesn't expose any operations. We only choose to expose `Shl<u32>` and `Shr<u32>` such that we can compute the min and max target thresholds allowed for a difficulty transition.

  This is something we realized was missing after bumping to `rust-bitcoin v0.30.0` in `rust-lightning`, specifically for our `lightning-block-sync` crate. It may also be worth having a helper in `rust-bitcoin` that checks a header properly builds upon the previous, but that can be left for future work.

dff757d7db Comment predict_weight (yancy)

Pull request description:

  I've been reading over the `predict_weight` function since it is one of the biggest challenges for coin-selection.  IE choosing inputs and constructing an optimal selection strategy requires predicting the weight to get the best selection.  It's great this work has been done but there are some things I don't understand well enough to comment.

  1) why are we looking at the size of VarInt struct here
  > let script_size = script_len + VarInt(script_len as u64).len()

  2) [predict_weight_internal](36500b4451/bitcoin/src/blockdata/transaction.rs (L1245)) has a bunch of magic numbers.  I'd like to be able to comment this as well but I don't fully understand that function.

  Also, `Transaction.rs` is a big file and it seems like all of the prediction stuff could be moved to a separate module or maybe a separate crate?

  It could happen that we unknowingly depend on a new version of a crate without updating `Cargo.toml`. This could cause resolution issues for downstream users. It's also unclear for outsiders to know with which dependencies did we test the crate.

  This change commits two lock files: `minimal` and `recent`. `minimal` contains minimal dependency versions, while `recent` contains dependency versions at the time of making the change.

  Further, this adds CI jobs to test with both lock files, CI job for `internals` crate, removes old `serde` pinning and prints a warning if `recent` is no longer up to date. (We may have to override it somehow if any crate breaks MSRV.)

  The documentation is also updated accordingly.

  Closes #1230

Deprecate min/max_value methods
Our previous MSRV did not support MIN/MAX associated consts so we had
methods min/max_value. Now that our MSRV is Rust 1.48.0 we can use the
consts.

Deprecate min/max_value methods in favor of MIN/MAX associated conts.

Use MIN/MAX consts instead of min/max_value
We currently use the functions `min_value` and `max_value` because the
consts were not available in Rust 1.41.1, however we recently bumped the
MSRV so we can use the consts now.

Add MIN/MAX consts to amounts
Add associated consts for minimum and maximum values to the `Amount` and
`SignedAmount` types.

Test with minimal dependency versions
It could happen that we unknowingly depend on a new version of a crate
without updating `Cargo.toml`. This could cause resolution issues for
downstream users. It's also unclear for outsiders to see which
dependencies we tested the crate with.

This change commits two lock files: `minimal` and `recent`. `minimal`
contains minimal depdendency versions, while `recent` contains
dependency versions at the time of making the change.

Further, this adds CI jobs to test with both lock files, CI job for
`internals` crate, removes old `serde` pinning and prints a warning if
`recent` is no longer up to date. (We may have to override it somehow if
any crate breaks MSRV.)

The documentation is also updated accordingly.

Merge rust-bitcoin/rust-bitcoin#1825: Simplify per-file license comments
1c3bbd4bf2 internals: Remove attribution from all files (Tobin C. Harding)
99673ab5c4 hashes: Introduce SPDX license identifiers (Tobin C. Harding)
984fe69448 bitcoin: Remove attribution from all files (Tobin C. Harding)

Pull request description:

  Please note, whether or not we need a per-file license comment is out of scope for this PR. This PR leaves us with the most simple per-file solution possible and leaves the merit of per-file license comment to be discussed on another day.

  Simplify the per-file license stuff by doing:

  - Remove the attribution line from each file.

      Currently we have a mishmash of attribution lines accompanying the SPDX identifier. These lines are basically meaningless because:

      - The date is often wrong
      - The original author attributed is not the only contributor to a file
      - The term "rust bitcoin developers" is basically just noise

  - Introduce SPDX license identifiers into `hashes` and remove attribution line (ie, make `hashes` uniform with `bitcoin`)

  Required before merge please:

  - [x] ack from apoelstra because as the library original author many of the changes in this PR remove his name
  - [x] ack from Kixunil because he had some concerns in the issue descussion

  Fix: #1816

bitcoin: Remove attribution from all files
Currently we have a mishmash of attribution lines accompanying the SPDX
identifier. These lines are basically meaningless because:

- The date is often wrong
- The original author attributed is not the only contributor to a file
- The term "rust bitcoin developers" is basically just noise

Just remove all the attribution lines and be done with it. While we are
at it add an SPDX line to the few files missing it, whether this license
nonsense is even needed is left as an argument for another day.

dd4ad9444e Hardcode expected weight in txin_txout_weight_tests (Peter Todd)

Pull request description:

  Rational: the expected weight is fixed so this both ensures we don't accidentally change it somehow, and makes it easier to re-use these test cases in other codebases (eg python-bitcoinlib).

Pull request description:

  Several big changes here:
  * Moves fuzzing to its own workspace with a `contrib/test.sh` etc so that CI will check that it compiles
  * FIx all warnings, clippy lints, MSRV problems, etc.; mostly move to Rust 2018
  * Merge `hashes/` fuzztests into workspace
  * Rewrite all scripts; add file that auto-generates CI fuzz job and Cargo.toml so we don't have to manually keep these in sync
  * Remove bitrotted and partial AFL support.

  Supercedes #1422

  I suspect the hashes fuzztests will actually fail since we haven't touched them in so long. Will address that if CI fails here.
