httpclient: apply change df9aea1def3e: remove use of two-argument raise

test-symlink-os-yes-fs-no.py: clean up use of two-argument raise This makes any attempt to port to Python 3 harder, and the new syntax is supported in 2.4 already.

test-command-template.t: fix test so it all year This test started failing for me after midnight UTC on December 31st. Fixed it by specifying a date 7 years in the future more precisely (rather than just adding 8 to the year and specifying January 1st), which allows the test to pass both now and on 2012-12-01 at the same time.

cmdutil: make getgraphlogrevs limit-aware For a repository with over 400,000 changesets, this speeds up graphlog with a small limit by around 0.05 seconds (~50%).

cmdutil: stop pretending we can calculate revs for graphlog lazily cmdutil.getgraphlogrevs does a ton of work trying to build a graphlog lazily, and then cmdutil.graphlog comes along and destroys all of that. graphmod.dagwalker requires that it be given the full list of revs upfront so that it can perform filtering and tests against known revs. For a repository with over 400,000 changesets, this speeds up graphlog by around 0.02 seconds (~20% with a small limit).

cmdutil: store a local ref to repo.hiddenrevs in getgraphlogrevs On a repository with over 400,000 changesets, this speeds graphlog up by around 0.03 seconds (~20% with a small limit).
