Tobin Harding 3f5caa501f Clean up module level rustdocs
Docs can always do with a bit of love.

Clean up the module level (`//!`) rustdocs for all public modules.

I claim uniform is better than any specific method/style. I tried to fit
in with what ever was either most sane of most prevalent, therefore
attaining uniformity without unnecessary code churn (one exception being
the changes to headings described below).

Notes:

* Headings - use heading as a regular sentence for all modules e.g.,

```
//! Bitcoin network messages.
```

as opposed to
```
//! # Bitcoin Network Messages
```

It was not clear which style to use so I picked a 'random' mature
project and copied their style.

* Added 'This module' in _most_ places as the start of the module
description, however I was not religious about this one.

* Fixed line length if necessary since most of our code seems to follow
short (80 char) line lengths for comments anyways.

* Added periods and fixed obvious (and sometimes not so obvious)
grammatically errors.

* Added a trailing `//!` to every block since this was almost universal
already. I don't really like this one but I'm guessing it is Andrew's
preferred style since its on the copyright notices as well.

Devrandom 4826d0c6cc no_std support
Based on the original work by Justin Moon.

*MSRV unchanged from 1.29.0.*

When `std` is off, `no-std` must be on, and we use the [`alloc`](https://doc.rust-lang.org/alloc/) and core2 crates. The `alloc` crate requires the user define a global allocator.

* Import from `core` and `alloc` instead of `std`
* `alloc` only used if `no-std` is on
* Create `std` feature
* Create `no-std` feature which adds a core2 dependency to polyfill `std::io` features. This is an experimental feature and should be
used with caution.
* CI runs tests `no-std`
* MSRV for `no-std` is 1.51 or so

Revert the sighash method signatures
Hash engines don't product I/O errors, so encoding into them
shouldn't produce errors either.

See docuemntation of the new method for more, but this allows
certain use patterns which were broken with the introduction of
SigHashCache.

bip143: Rename witness_script to script_code
For p2wsh the scriptCode is the witness script, but for p2wpkh, it's the
equivalent legacy p2pkh output script.
The name scriptCode is used in the BIP, so it's less confusing.

Jean Pierre Dudey 32631e44ad Rename `TxOutRef` to `OutPoint` and use it in `TxIn`.
Previously this structure was unused, it's now being used by the `TxIn`
structure to simplify the code a little bit and avoid confusions. Also
the rust-lightning source code has an `OutPoint` similar to this one
but with the `vout` index as an `u16` to avoid unsafe conversions.

I've added to new methods to `OutPoint`:

- `null`: Creates a new "null" `OutPoint`.
- `is_null`: Checks if the given `OutPoint` is null.

Savil Srivastava 933dcaeb82 [code hygiene] remove deprecated rustc-serialize
Addresses #96.

Turns out it was being used for hex encoding/decoding, so replaced that with the `hex` crate.

i chose to import the `decode` method as:
```
use hex::decode as hex_decode
```

so that it is clear to the reader what is being decoded when it is called. "decode" is such a generic sounding function name that it would get confusing otherwise.

Matt Corallo 0e1d927b47 Only provide the required TxIn to bip143 sighash_all.
This resolves an very unergonomic API by allowing iteration over a
Transaction being signed's inputs without needing to take a
conflicting reference to the transaction.

The API is still relateively unsafe in that its very easy to
generate bogus sighashes with it, but this is much better than it
was, and its not clear how to fix it further.
