tags-cache: add a dedicated warm cache function to hgtagsfnodescache
Having a dedicated API point will help to optimize that specific usage. Right
doing a full phases weam takes a long time, even when the cache is already
filled.
To run the tests, do:
cd tests/
python run-tests.py
See https://mercurial-scm.org/wiki/WritingTests for
more information on writing tests.
