largefiles: factor out procedures to update lfdirstate for post-committing
Before this patch, procedures to update lfdirstate for post-committing
are scattered in "lfilesrepo.commit". In the case of "hg commit" with
patterns for target files ("Case 2"), lfdirstate is updated BEFORE
real committing.
This patch factors out procedures to update lfdirstate for
post-committing into "lfutil.markcommitted", and makes it callable via
"markcommitted" of the context passed to "lfilesrepo.commitctx".
"markcommitted" of the context is called, only when it is committed
successfully.
Passing original "markcommitted" of the context is meaningless in this
patch, but required in subsequent one to prepare something before
invocation of it.
# simple script to be used in hooks
#
# put something like this in the repo .hg/hgrc:
#
# [hooks]
# changegroup = python "$TESTDIR/printenv.py" <hookname> [exit] [output]
#
# - <hookname> is a mandatory argument (e.g. "changegroup")
# - [exit] is the exit code of the hook (default: 0)
# - [output] is the name of the output file (default: use sys.stdout)
# the file will be opened in append mode.
