d2ed0fe022 Add `impl IntoIterator for &'_ Witness` (Martin Habovstiak)
Pull request description:
It is considered idiomatic for types that have `iter()` method to also implement `IntoIterator` for their references. `Witness` was missing this so it is added here.

Pull request description:
Now we have MSRV of 1.41.1 we can use the `from_le_bytes` and `to_be_bytes` methods implemented on standard integer types, these became available in Rust 1.32.
Remove the `endian` module replacing its logic with calls to methods on the respective stdlib integer types.

fd7f8daeff Move sighash module to crate root (Tobin C. Harding)
Pull request description:
Done as part of the effort to flatten the `util` module.
The `sighash` module can stand alone in the crate root, it provides a discreet set of functionality - the `SighashCache` and associated types.
Marking as high priority because this is part of flattening `util` which is a required step before we start crate smashing.

Done as part of the effort to flatten the `util` module.
The `sighash` module can stand alone in the crate root, it provides a
discreet set of functionality - the `SighashCache` and associated types.
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
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.

A zero default value for `Target` and `Work` has no significance and/or
usecase, remove the derived `Default` implementation.
Includes making `Target::ZERO` public.

Currently we use the `Uint256` type to represent two proof of work
integers, namely target and difficulty (work).
It would be nice to not have a public integer type that is not fully
implemented (i.e., does not implement arithmetic etc as do integer types
in stdlib). Instead of implementing all the stdlib functions we can
instead add two new wrapper types, since these are not general purpose
integers they do not need to implement anything we do not need to use.
- Add a `pow` module.
- Put a modified version of `Uint256` to `pow`.
- Add two new wrapper types `Target` and `Difficulty`.
- Only implement methods that we use on each type.
Note this patch does not remove the original `Uint256`, that will be
done as a separate patch.
