hooklib: fix detection of successors for changeset_obsoleted
Provide a hook for obsutil.getobsolete to be used with either a
transaction or the changes item of the transaction, since hooks only
have access to the latter. Use that to find the correct list of
revisions with obsmarkers, even new ones, and then filter out revisions
with known successors.
Move the processing from pretxnclose to txnclose as the transaction
access itself is no longer necessary. This is more in line with notify
and ensures that sanity checks can abort the transaction first.

== 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.
