Merge rust-bitcoin/rust-bitcoin#983: Edition 2018
9f0c687d89 Enable edition 2018 (Tobin C. Harding)
dca0d67771 Fix in preparation for next edition (Tobin C. Harding)

Pull request description:

  This PR supersedes #635 at the permission of @Kixunil in the thread of that PR.

  Do a minimal set of changes to enable edition 2018.  Patch 1 is  the biggest change set, it is done with `cargo`, no other manual changes are included in patch 1.  It can verified by running `cargo fix --edition` on master and checking the diffs are the same.

  Patch 2 enables 2018 and includes all the manual changes required to get the code to build (with _all_ the feature combinations :)

Tobin C. Harding 38c41e4612 Replace base64-compat dependency
Now that we have MSRV 1.41.1 we can use the more modern `base64` instead
of the compat crate. Requires no changes other than changing the
dependency.

Tobin C. Harding dca0d67771 Fix in preparation for next edition
Use cargo to upgrade from edition 2015 to edition 2018.

 cargo fix --edition

No manual changes made. The result of the command above is just to fix
all the use statements (add `crate::`) and fix the fully qualified path
formats i.e., `::Foo` -> `crate::Foo`.

Merge rust-bitcoin/rust-bitcoin#989: Add method to push an ECDSA sig + sighash type byte on a witness
0ab5eeac81 Add method to push an ECDSA sig + sighash type byte on a witness (Matt Corallo)

Pull request description:

  We do this all over the place in rust-lightning, and its probably
  the most common thing to do with a `Witness` so I figured I'd
  upstream the util method to do this. It also avoids an allocation
  compared to the naive approach of `SerializedSignature.to_vec()`
  with two pushes, which is nice.

Merge rust-bitcoin/rust-bitcoin#716: Add `amount::Display` - make formatting configurable
4f1200d629 Added `amount::Display` - configurable formatting (Martin Habovstiak)

Pull request description:

  This significatnly refactors the formatting code to make formatting more
  configurable. The main addition is the `Display` type which is a
  builder that can configure denomination or other things (possibly more
  in the future).

  Further, this makes all representations of numbers minimal by default,
  so should be documented as a possibly-breaking change.

  Because of the effort to support all other `fmt::Formatter` options this
  required practically complete rewrite of `fmt_satoshi_in`. As a
  byproduct I took the opportunity of removing one allocation from there.

  Closes #709

Pull request description:

  This refactors `blockdata::script::Instructions` to use
  `::core::slice::Iter<'a, u8>` instead of `&'a [u8]` to better express
  the intention and to avoid some slicing mistakes. Similarly to a
  previous change this uses a macro to deduplicate the common logic and
  the new `read_uint_iter` internal function to automatically advance the
  iterator.

Merge rust-bitcoin/rust-bitcoin#690: BUG: Does not work with `no_std` under 1.29 (MSRV)
7854bd7918 Fix `no_std` MSRV Fixes #690, #947 (mcroad)

Pull request description:

  `rust-bitcoin` does not work with rust 1.29 under a `no_std` environment. This could be considered a bug. However, `no_std` support is a recent addition and this is likely not breaking anyone's builds.

  A decision needs to be made, either `no_std` MSRV is the current stable version while keeping the `std` MSRV as 1.29, or it needs to be fixed.

  This pr adds `no_std` to the 1.29 test suite.

  This came as I try to get rust-bitcoin/rust-miniscript#277 working and got stuck on the issue of testing `no_std` under 1.29.

Tobin C. Harding 21e1b9dbbd Use secp256k1 qualified path instead of underscore
We can use the qualified path for create type aliases, this is arguably
easier to read and reduces the number of LOC.

Tobin C. Harding 033a12def7 Remove unused Write as _fmtWrite
We can bring the `Write` trait into scope, no need to underscore it.

Merge rust-bitcoin/rust-bitcoin#954: Add Script conversion method p2wpkh_script_code
d882b68a2c Add Script conversion method p2wpkh_script_code (Tobin Harding)

Pull request description:

  In order to sign a utxo that does a p2wpkh spend we need to create the
  script that can be used to create a sighash. In the libbitcoin docs this
  is referred to as the 'script code' [0] (also described in BIP143)

  The script is the same as a p2pkh script but the pubkey_hash is found in
  the scriptPubkey.

  Add a `Script` conversion method that checks if `self` is a v0 p2wpkh
  script and if so extracts the pubkey_hash and returns the required
  script.

  Includes a link to BIP143

Merge rust-bitcoin/rust-bitcoin#951: Add PSBT alias
f92854a805 Add PSBT alias (Tobin Harding)

Pull request description:

  Programmers are inherently lazy and for good reason. I'm yet to see
  anyone write `PartiallySignedTransaction` in code that uses
  `rust-bitcoin`, its too obvious to add a type alias for PSBTs, let's
  just do it ourselves to save everyone else having to do so.

  Add public type alias `Psbt` for `PartiallySignedTransaction`.

Merge rust-bitcoin/rust-bitcoin#939: fix: reject message (de)serialization
548725c5fb test: reject message (de)serialization (0xb10c)
fc572aba86 fix: use var_str in 'reject' msgs (0xb10c)

Pull request description:

  [BIP-61 defines `response-to-msg`][bip61] (`Reject::message` in rust-bitcoin; the message that triggered the reject) to be a `var_str`. However, by using the `CommandString` it was (de)serialized as 12 byte string. A test is added that de- and serializes two reject messages received from an older Bitcoin Core peer.

  Reject message sending has been removed from Bitcoin Core, I'm still receiving them from older peers from time to time.
