tags: support setting hgtags fnodes cache entries
An upcoming patch will teach bundle2 to transfer .hgtags fnodes
values. To support this, we need to support inserting values into
the cache.
Add functionality to do that.
Set vars:
$ CONTRIBDIR="$TESTDIR/../contrib"
Prepare repo-a:
$ hg init repo-a
$ cd repo-a
$ echo this is file a > a
$ hg add a
$ hg commit -m first
$ echo adding to file a >> a
$ hg commit -m second
$ echo adding more to file a >> a
$ hg commit -m third
$ hg verify

Dump all revlogs to file repo.dump:
$ find .hg/store -name "*.i" | sort | xargs python "$CONTRIBDIR/dumprevlog" > ../repo.dump
$ cd ..
Undumping into repo-b:
$ hg init repo-b
$ cd repo-b
$ python "$CONTRIBDIR/undumprevlog" < ../repo.dump
.hg/store/00changelog.i
.hg/store/00manifest.i
