b6f9e47dba Fix `no_std` when `bitcoinconsensus` is enabled (Martin Habovstiak)
Pull request description:
`default-features = false` was missing previously but blindly adding it would lead to subtle risk of breaking when a crate not needing `std` depends on `bitcoinconsensus` and simultaneously another crate not needing `bitcoinconsensus` depends on `std` and another crate depends on them both.
This change fixes it by introducing `bitcoinconsensus-std` feature flag and provides a fallback if the flag is off. Unfortunately the fallback has to use a bit of reasonable `unsafe` due to limitations of upcasting.
The only safe alternatives are not do it and provide worse experience for crates that are affected by the problem above or break the API, which couldn't be backported and would be more annoying to use.
Closes#1343
This is considered PoC PR as I realized the possibility of the hack (and necessity of `unsafe`) at the last moment. Things like tests and modifying CONTRIBUTING to change the stance on `unsafe` will be added if `unsafe` is ACKed.

22dd904735 Rename util::hash module (Tobin C. Harding)
Pull request description:
Done as part of flattening `util`.
The `util::hash` module only provides two functions, both to calculate the merkle root of a list of hashes.
1. Rename `util::hash` -> `crate::merkle_root`
2. Change function names to `calculate[_inline]` so usage becomes `merkle_root::calculate`
Done as two separate patches so we can bikeshed the names, can squash if needed.

This transaction broke past versions of `rust-bitcoin` and LND so this
adds a test to avoid reintroducing the problem in the future.
See also https://github.com/romanz/electrs/issues/783
The function call `calculate_root_inline` calculates the merkle root
using the input array as a scratch buffer, i.e., we trash the data
during recursive calls to `merkle_root_r`.
Add explicit documentation to the function so its super clear not to use
the hashes again after calling this function.
Recently we renamed the `hash` module to `merkle_root`, this makes the
public functions provided stutter if used with one layer of path as is
Rust convention:
`merkle_root::bitcoin_merkle_root`
We can improve on this by renaming the functions to 'calculate', then we
get
- `merkle_root::calculate()`
- `merkle_root::calculate_inline()`
The `util::hash` module provides two functions for computing a merkle
root from a list/iterator of hashes.
Rename the module to `merkle_root` and move it to the crate root,
deprecate the original functions.

We have all of the opcodes defined in a submodule called `all`, this
allows wildcard imports without bringing in the other types in the
`opcodes` module.
Use wildcard import `use crate::blockdata::opcodes::all::*` instead of
fully qualifying the path to opcodes.

Closes ##1154
Done as part of flattening the `util` module. Simply move the `amount`
module out of the `util` module and to the crate root. Justified by the
fact that the `Amount` type is more-or-less a "primitive" bitcoin type.
In preparation for emptying the `internal_macros` module move the
`serde_string_impl` and `serde_struct_human_string_imp` macros to the
`serde_utils` module.
Rationale: `internal_macros` stuff can go over in the `internals` crate
now that we have one. The serde macros could go over there but we have a
`serde_utils` module that holds code for implementing serde traits,
these two macros are exactly that.
`impl_array_newtype` is an internal macro, move it to a new, ever so
meaningfully named, `macros` module.
Use `#[macro_export]`, no other changes to the macro.
Signing a PSBT requires no knowledge other than what we have here in
this library and the PSBT ready to be signed.
This code was pulled out of `rust-miniscript`.
Add a `sign` method to the `PartiallySignedTransaction`.
The import statements in `psbt/mod.rs` are a bit of a mess, re-order
them in an attempt to group like things and separate out things that are
different (e.g. `pub use` from `use`).
Refactor only, no logic changes.

02a2b43b2b Remove Default impl for Target and Work (Tobin C. Harding)
cb9893c4a9 Add Target and Difficulty types (Tobin C. Harding)
Pull request description:
Ugh! 1600 lines of green and 1100 of red - my apologies.
Currently we use the `Uint256` type for proof-of-work calculations. It was observed in #1181 that providing a public 256 bit integer type like this implies that it is a general purpose integer type. We do not want to provide a general purpose integer type (see the 1000 arithmetic functions on stdlib integer types for why not :)
Add two new opaque integer types `Target` and `Work`. These are the inverse of each other, both conceptually and mathematically.
There is a lot of code in this PR, sorry about that. At a high level the PR does:
- Add a `pow` module.
- Put a modified version of `Uint256` in `pow`, making it private.
- Add two new wrapper types `Target` and `Work` that provide a very limited API specific to their use case. In particular there are methods on each to convert to the other.
- Only implement methods that we use on each type.
### Note
During development I got mixed up with the word "difficulty", I have discovered this has a very specific meaning in Bitcoin. Please see rustdocs on the `Target::difficulty` function for explanation of this term. For this reason we use the type `Work` defined as the inverse of target, and reserve "difficulty" for the Bitcoin concept.
