097e4e9c7f Fix license on bip158 module (Tobin C. Harding)
Pull request description:
When we introduced the SPDX license blurb in [0] we incorrectly gave attribution to Andrew when the original file author had the attribution as "the rust-bitcoin developers". The original author [1] was Tamas Blummer and he copied this code from code he wrote and explicitly re-licenses it. In order to make the re-licensing comment a little clearer and fix the mis-attribution use Tamas' name in the attribution.

Pull request description:
Currently we have an attempted tag ```compile_fail that seems to be aiming at allowing code that does not build to exist in rustdoc. This is causing an error when running tests.
No clue how this made it through CI.

In some scenarios it's useful to create outputs with minimal relayable
value. E.g. outputs designated for fee bumping using CPFP. A method for
this is useful.
This implements a constructor of `TxOut` that computes the minimal
non-dust value from the passed script.
Closes#1459
When creating a transaction one must know the the fee beforehand to set
appropriate amounts for outputs and to know the fee, weight is required.
So far we only had a method on an already-constructed transaction. This
method clearly wasn't helpful when constructing the transaction except
for hacks like temporarily adding an all-zeroes signature.
This change adds a function that can compute the transaction weight
without knowing individual bytes of the scripts, witnesses and other
elements. It only needs to know their sizes.
To make the API less error-prone a special, trivial, type is also added
for computing the lengths of witnesses.

Patch one does the deprecation, the rest of the PR is made up of tiny improvements to the code around reading/writing 'scriptint's (conceptually `CScriptNum`s). I did all this while trying to decipher the discussion on #1547.
### Note Please
There are many more changes in the pipeline for all this read/write "script int" stuff. This PR was done ages ago and I believe it stall adds value.
I re-did the whole PR manually because of the recent `script` module changes. I hope no one else has to do that - if you do please feel free to holla and I'll "rebase" your PR for you.

I'm closing #1571 because it is now done more fully at the end of this PR.
During review please be liberal with any questions so we can ensure everything is spot on now - as we add more crates there are going to be a proliferation of manifest files, best get it right now.

Currently we implement string parsing for height/time from the
`absolute` module but not the `relative` module.
Improve the macros used to implement string parsing and use the new
versions to implement string parsing for the height and time types in
`relative`.
Lock times are u32 and can necessitate encoding using 5 bytes. As such
they are "special".
Add methods `push_lock_time` and `push_sequence` for pushing absolute
lock times and sequence numbers. We do not push relative locktimes
because they are only 16 bits from the original sequence number.
Our `script::read_scriptint` function is based on the constructor
code (incl. call to `set_vch`) code from Bitcoin Core. Add rustdoc
comment saying so, emit a link because there are already multiple links
to `script.h` in this file (one just right below the added comment).
We only support reads of upto 4 bytes where as Bitcoin Core allows
reading a `CScriptNum` with more bytes than that. Add a rustdoc
comment (incl. link to Bitcoin Core) mentioning that.
Our `Builder::push_int` method is the same as Bitcoin Core `CScript`
`push_int64` method. We currently use `OP_FALSE` (equivalent to `OP_0`)
but recently we added `OP_0`, lets use it to make our code better mimic
Core (also saves devs checking that `OP_FALSE` is the same as `OP_0`).
The `MerkleBlock` struct is the main type in this file, put it at the
top of the file. This leaves the next most important type,
`PartialMerkleTree` below that.
Refactor only, no logic changes.

a9108d3939 Refactor script module (Tobin C. Harding)
Pull request description:
The `script` module is large and unwieldy.
Refactor the `script` module, splitting it up into a tree of modules. Here are a few of the changes and their stated benefits
- Split the two script types out into separate files: Readers of the methods can then tell immediately from the file name which type they are reading.
- Put all the impls for the two script types together: Makes parsing the API easier because one can more quickly see which traits are implemented on what i.e., all the `AsRef` imlps are grouped together.
- Put the impls for the two script types in order, first `Script` then `ScriptBuf`: Makes it easier for us to see if we missed something.
- Put the `Builder` and `Instruction` (and associated) types in their own modules: Some devs find long files hard to navigate, so far there hasn't been too much push back against short files.
- Put tests in a separate file: This idea was recently discussed.
This is only moving code and fixing import statements etc. No other changes to the code.
## Note to reviewers
This PR is impossible to review from the diff because it moves so much code. Perhaps better to look at the resulting `src/blockdata/script/` directory and see if you like it.
#### Motivation
While adding script tagging I was having difficulty navigating the script module.

Clean up the optional dependencies by doing:
- Put the optional dependencies below the non-optional dependencies as
is customary, separated by a line of whitespace.
- Put `optional = true` as the last item so as to be uniform
- Put `core2` at the top, aids reading because of how the comments are
distributed (`core2` does not have a comment on it).
Improve std/alloc features by doing:
- Fix incorrect feature enabling: "std" should enable "internals/std"
not "internals/alloc".
- Put the "alloc" feature under the "std" feature, same as in other
crates.
- Remove the comment, devs should understand what dependencies are for.
We don't have comments everywhere else so we don't really need this one.
Use of general-purpose integers is often error-prone and annoying. We're

Part of #630
In `bitcoin` when we use the `core2` dependency we always need the
"alloc" feature. Enabling "alloc" when enabling "core2" in the "no-std"
feature is confusing because it makes it seem that we don't always need
it.
Set usage of the "alloc" feature of `core2` in the `features` list.
`core2` is for Read/Write, nothing to do with allocation and we do not
use the "alloc" feature of `core2` in `hashes`.
Fix core2 dependency/features by doing:
- Explicitly enable "bitcoin_hashes/core2" in `bitcoin`.
- Do not enable "core2/alloc" in `hashes`
Improve all manifest package sections by doing:
- Order the list of options uniformly
- Remove unnecessary homepage option (currently same as repo)
- Add categories section
We can check which files are included in the packaged release with
`cargo package --list `.
Add an `exclude` section to each manifest that excludes `tests/` and
`contrib/`. Not all crates have a `tests/` directory yet but they should
so add the exclude anyway to future proof the crates.

It may be useful to access the transaction stored in `SighashCache`
during signing or afterwards, especially when the transaction is stored
without indirection (to enable long-lived storage).
This change adds the appropriate accessors.
The requirement for a type dereferencing to `Transaction` prevented
storing the cache in long-lived data without resorting to silly
wrappers. Since `Borrow` is implemented both for `T` and for smart
pointers it's a more flexible bound which this change implements.
While this is technically breaking, all usual non-generic code will
continue to work beause smart pointers generally have `Borrow`
implemented.
Currently we use a wildcard to export all the hash types in
`hash_types`. We are moving to a world were we only export
normal/standard types from the crate root.
Remove the reexport of the following hash types:
- `FilterHash`
- `FilterHeader`
- `TxMerkleNode`
- `WitnessCommitment`
- `WitnessMerkleNode`
- `XpubIdentifier`
- `Sighash`
Fix: #1541
