obsolete: introduce caches for all meaningful sets This changeset introduces caches on the `obsstore` that keeps track of sets of revisions meaningful for obsolescence related logics. For now they are: - obsolete: changesets used as precursors (and not public), - extinct: obsolete changesets with osbolete descendants only, - unstable: non obsolete changesets with obsolete ancestors. The cache is accessed using the `getobscache(repo, '<set-name>')` function which builds the cache on demand. The `clearobscaches(repo)` function takes care of clearing the caches if any. Caches are cleared when one of these events happens: - a new marker is added, - a new changeset is added, - some changesets are made public, - some public changesets are demoted to draft or secret. Declaration of more sets is made easy because we will have to handle at least two other "troubles" (latecomer and conflicting). Caches are now used by revset and changectx. It is usually not much more expensive to compute the whole set than to check the property of a few elements. The performance boost is welcome in case we apply obsolescence logic on a lot of revisions. This makes the feature usable!

test-http-branchmap: enable on Windows Tests using "hg serve --daemon" are currently disabled on Windows for lack of proper kill utility. The one shipped with MinGW operates on internal process identifiers and not on the ones recorded by hg serve. Fortunately we can replace most of them by calls to killdaemons.py. This patch is a proof of concept on how to run these tests on Windows. The plan is: - Check test-http-branchmap.t does not fail/hang on the buildbot - Convert all kill utility calls to killdaemons.py calls. - Add a rule in check-code.py to forbid kill calls, or ignore the remaining ones (test-hup.t, etc.). - Possibly drop the 'serve' rule from hghave. The: listening at http://*:$HGPORT1/ line does not appear on Windows because the detached process can no longer write on its parent streams. Grepping hg serve stdout directly causes the parent process to never return and hangs the test. This is a bug, but I have no simple solution and prefer to pay this small price and enable hg serve tests on Windows.

killdaemons: take file argument explicitely It makes it easier to use as a generic replacement for kill utility, mostly for Windows tests.

killdaemons: add windows implementation

run-tests: do not duplicate killdaemons() code

bash_completion: add rebase rev completion

tests: correct quoting of double quotes in here documents used to write hooks Some shells, e.g. ksh89, will emit \" in a here document as ", while others will emit \". To be sure of getting \", we specify \\". This gets test-commit-amend.t and test-largefiles.t working on AIX.

amend: preserve phase of amended revision (issue3602) New commit from the amend process were created without any phase contraint. If the amended changeset had a different phase from it's parent, the phases data were lost. The changeset ensure the new commit are created in the same phase than the original changeset.
