rust-node: binary Node ID and conversion utilities
The choice of type makes sure that a `Node` has the exact
wanted size. We'll use a different type for prefixes.
Added dependency: hexadecimal conversion relies on the
`hex` crate.
The fact that sooner or later Mercurial is going to need
to change its hash sizes has been taken strongly in
consideration:
- the hash length is a constant, but that is not directly
exposed to callers. Changing the value of that constant
is the only thing to do to change the hash length (even
in unit tests)
- the code could be adapted to support several sizes of hashes,
if that turned out to be useful. To that effect, only the
size of a given `Node` is exposed in the public API.
- callers not involved in initial computation, I/O and FFI
are able to operate without a priori assumptions on the hash
size. The traits `FromHex` and `ToHex` have not been directly
implemented, so that the doc-comments explaining these
restrictions would stay really visible in `cargo doc`

== New Features == * Windows will process hgrc files in %PROGRAMDATA%\Mercurial\hgrc.d. == New Experimental Features == == Bug Fixes == * The `indent()` template function was documented to not indent empty lines, but it still indented the first line even if it was empty. It no longer does that. == Backwards Compatibility Changes == == Internal API Changes == * Matcher instances no longer have a `explicitdir` property. Consider rewriting your code to use `repo.wvfs.isdir()` and/or `ctx.hasdir()` instead. Also, the `traversedir` property is now also called when only `explicitdir` used to be called. That may mean that you can simply remove the use of `explicitdir` if you were already using `traversedir`. * The `revlog.nodemap` object have been merged into the `revlog.index` object. * `n in revlog.nodemap` becomes `revlog.index.has_node(n)`, * `revlog.nodemap[n]` becomes `revlog.index.rev(n)`, * `revlog.nodemap.get(n)` becomes `revlog.index.get_rev(n)`. * `copies.duplicatecopies()` was renamed to `copies.graftcopies()`. Its arguments changed from revision numbers to context objects. It also lost its `repo` and `skip` arguments (they should no longer be needed).
