Merge

manifestmerge: handle abort on local unknown, remote created files This replaces the _checkunknown call in calculateupdates with a more performant version. On a repository with over 150,000 files, this speeds up an update by 0.6-0.8 seconds, which is up to 25%. This does not introduce any UI changes. There is existing test coverage for every case, mostly in test-merge*.t.

manifestmerge: pass in branchmerge and force separately This will be used in an upcoming patch.

manifest: use a size 3 LRU cache to store parsed manifests Previously, the manifest cache would store the last manifest parsed. We could run into situations with operations like update where we would try parsing the manifest for a revision r1, then r2, then r1 again. This increases the cache size to 3 to avoid that bit of performance fragility.

util: add an LRU cache dict In certain cases we would like to have a cache of the last N results of a given computation, where N is small. This will be used in an upcoming patch to increase the size of the manifest cache from 1 to 3.

tests: remove last two check-code warnings about killdaemons Removes the last of the warnings in test-check-code-hg.t introduced in 667063b22a69.

tests: guard against obsolete markers in the hg repo itself If obsolete markers appear in the hg repo (because of enabling evolve), then tests that run hg against the hg repo itself will see warnings like: obsolete feature not enabled but 4 markers found! As far as I can tell, this only occurs in test-check-code-hg.t -- in particular, it will -not- show up on tests that run against test-created repos, as most of the test suite does.

largefiles: make caching largefiles message more explicit In some cases, caching largefiles may take a long time (if the user has pulled a lot of new heads). This patch makes it more clear what is happening, by showing the number of heads we are caching largefiles for.
