phases: use revision number in new_heads
All graph operations will be done using revision numbers, so passing nodes only
means they will eventually get converted to revision numbers internally.
As part of an effort to align the code on using revision number we make the
`phases.newheads` function operated on revision number, taking them as input
and using them in returns, instead of the node-id it used to consume and
produce.
This is part of multiple changesets effort to translate more part of the logic,
but is done step by step to facilitate the identification of issue that might
arise in mercurial core and extensions.
To make the change simpler to handle for third party extensions, we also rename
the function, using a more modern form. This will help detecting the different
between the node-id version and the rev-num version.
I also take this as an opportunity to add some comment about possible
performance improvement for the future. They don't matter too much now, but they
are worse exploring in a while.

Mercurial ========= Mercurial is a fast, easy to use, distributed revision control tool for software developers. Basic install:: $ make # see install targets $ make install # do a system-wide install $ hg debuginstall # sanity-check setup $ hg # see help Running without installing:: $ make local # build for inplace usage $ ./hg --version # should show the latest version See https://mercurial-scm.org/ for detailed installation instructions, platform-specific notes, and Mercurial user information. Notes for packagers =================== Mercurial ships a copy of the python-zstandard sources. This is used to provide support for zstd compression and decompression functionality. The module is not intended to be replaced by the plain python-zstandard nor is it intended to use a system zstd library. Patches can result in hard to diagnose errors and are explicitly discouraged as unsupported configuration.
