The spec RFC3986 specifies the scheme is case insensitive and we were uppercasing
to optimize QR code representation.
Unfortunately, common platform such as Android seems to fail to recognize
uppercase schema, so for compatibility reason we use lowercase.
75b3f19b96 Move and rename TxOut default trait to a const called NULL (yancy)
Pull request description:
Create an associated constant `const TxOut::NULL` for consensus signing code and remove the default trait. Note I tried to deprecate the `default()` fn instead of just removing it but it doesn't seem to be possible. Also because `TxOut::NULL` is `const`, `ScriptBuf::new()` needed to be changed to `const fn`.

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?

814b9917da address: Add Sync, Send, Sized and UnPin marker traits on NetworkValidation (Steven Roose)
Pull request description:
With the new rewrite of Address, `serde::Serialize` is only implemented on `Address<bitcoin::address::NetworkChecked>` and `Address<bitcoin::address::NetworkUnchecked>`. But the compiler has no way of knowing that that are all the possible versions of `Address`, so the generic `Address<impl bitcoin::address::NetworkValidation>` doesn't implement `serde::Serialize`.

c4c64c0dc5 Test with minimal dependency versions (Martin Habovstiak)
d5655d503a Bump core2 dependency from 0.3.0 -> 0.3.2 (Tobin C. Harding)
Pull request description:
This is work originally done by Kixunil in #1272, I picked it up to help out. The only changes I made were rebasingg, updating the recent lock file, adding `--locked` to hashes contrib file, and adding a co-developed-by tag for accountability.
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.

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.
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.

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

nonsense is even needed is left as an argument for another day.

* 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.

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

Done as is single patch to make sure all the docs and CI are in sync and
correct.
We currently pin the `schemars` dependency using `<=0.8.3` as well as a
the `dyn-clone` transient dependency in the manifest (`hashes` and the
extended test crate). This is incorrect because it makes usage of the
crate klunky (or possibly impossible) if downstream users wish to use a
later version of `schemars`.
Observe also that we do not have to pin `schemars`, we do however have to pin
the `serde` crate if either `serde` or `schemars` features are enabled.
Do so in CI and document in the readme file within hashes.
Currently we have a pin remaining from the old MSRV (`syn` due to use
of `matches!`).
Fix pinning by:
- Remove pin in manifest for `schemars`
- Fix pinning for MSRV in CI and docs (this includes documenting pinning
requirements for `schemars` feature because it is related to the other
pin of `serde`) in both `hashes` readme and main repo readme.

`hash_newtype!` macro but didn't for sha256t version.
This changes the macro to have this syntax:
```rust
sha256t_hash_newtype! {
// Order of these structs is fixed.
/// Optional documentation details here. Summary is auto-generated.
/*pub*/ struct Tag = raw(MIDSTATE_BYTES, LEN);
/// Documentation here

This commit refactors the Address struct and its methods to improve
its functionality and usability.The AddressInner struct now holds
the payload and network, and the PhantomData<V> type is used to track
the network validation state.
Also as_unchecked and assume_checked_red methods are added to allow
conversion between checked and unchecked network validation state.
