scmutil: allowing different files to be prefetched per revision
The old API takes a list of revision separate from the file matcher, and thus
provides no way to fetch different sets of files from each revision. In
preparation for adding one such usage, I'm changing the API to take a list of
(revision, file matcher) tuples instead.

== New Features == * clonebundles can be annotated with the expected memory requirements using the `REQUIREDRAM` option. This allows clients to skip bundles created with large zstd windows and fallback to larger, but less demanding bundles. == New Experimental Features == * The core of some hg operations have been (and are being) implemented in rust, for speed. `hg status` on a repository with 300k tracked files goes from 1.8s to 0.6s for instance. This has currently been tested only on linux, and does not build on windows. See rust/README.rst in the mercurial repository for instructions to opt into this. == Backwards Compatibility Changes == * Mercurial now requires at least Python 2.7.9 or a Python version that backported modern SSL/TLS features (as defined in PEP 466), and that Python was compiled against a OpenSSL version supporting TLS 1.1 or TLS 1.2 (likely this requires the OpenSSL version to be at least 1.0.1). * The `hg perfwrite` command from contrib/perf.py was made more flexible and changed its default behavior. To get the previous behavior, run `hg perfwrite --nlines=100000 --nitems=1 --item='Testing write performance' --batch-line`. == Internal API Changes == * logcmdutil.diffordiffstat() now takes contexts instead of nodes. * The `mergestate` class along with some related methods and constants have moved from `mercurial.merge` to a new `mercurial.mergestate` module.
