The `as_script_map` is a getter not a conversion function (to/into/as),
as such it should not include the prefix `as_`.
Deprecate `as_script_map` in favour of `script_map`.
06afd52a12 Improve hashes::Error (Tobin C. Harding)
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`.

Add a `ValidationError` to the `block` module and remove the two
variants out of `crate::Error`.
This error is only used by the `validate_pow` function, a specific error
better serves our purposes.

No idea why this re-export is here, the `Prevouts` type is not even used
in the `psbt` module.
Remove the re-export of `crate::sighash::Prevouts` from `pstb`.
013dffa65d tests: Use script hash methods (Tobin C. Harding)
Pull request description:
The `ScriptBuf` type can be serialized using it's `to_bytes` function. Do not use the `psbt::Serialize` trait to do so in test code.
No logic changes, since the impl of `psbt::Serialize` for `ScriptBuf` just calls `to_bytes`.

We have methods to convert a script to a `WScritpHash` and `ScriptHash`,
no need to do this manually, let alone use the `psbt::Serialize` trait
to do so.
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.

8835d5d2f1 make bip21 schema lowercase (Riccardo Casatta)
Pull request description:
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.

Pull request description:
Numbers with only zeros after decimal points are valid if they are also
multiples of `10^precision` (e.g. 1000 for msats). These were
artificially disallowed as "too precise" which was at least misleading.
This change allows parsing such numbers.
And yes, I know this is not perfectly efficient (unless the compiler figures out some magic opts) but so isn't the rest of the code. TBH this parsing code drives me crazy and I'd love to rewrite it to be more efficient and readable.

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?

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`.

Once `U256` was made private, we lost the ability to check whether a
valid difficulty transition was made in the chain, since `Target`
no longer exposes any arithmetic operations.
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.
