tests: add glob for Windows

tests: adds simple test case for heads checking This is the start of some systemic testing of the head superceeding detection mechanism.

tests: move exchange utility in testlib We have a testlib directory now lets use it.

exchange: fix some wrong reference to serveronly The function have all moved into 'obsexchange' now, so we do not need (and actually cannot) seek them in 'evolve.serveronly'.

checks: add a test that check MANIFEST.in content This make sure we keep the things updated.

README: add a link to mercurial devel This will help people to find the mailing list details.

README: tries to improve the title about server only This seems a bit better.

README: remove mention of make Using pip in all cases seems a better direction.

version: mark the current source as development version for 6.0.0 This is useful to distinguish the development version from the latest tagged version. In this particular case, this will allow us to publish a pre-version on pypi.

mercurial-3.8: merge with future evolve-6.0.0 We introduces the new code on the compat branch to check the tests.

mercurial-3.9: merge with hg-4.0 branch We merge with the code for the future evolve 6.0.0 code to check for compatibility. Only minor test output change (" -> ') have been noted.

mercurial-4.0: merge with future 6.0.0 A new version will be released soon, we start handling mismatch in test output to make the actual release time smoother.

checks: update pyflakes matching too We make sure to not select removed files.

checks: do not run pyflake on removed file The fileset matches removed files. This confuses pyflakes for good reasons.

compat: closing mercurial-3.7 compatibility branch The "evolve-6.0.0" release drop compatibility with Mercurial 3.7. No new commit are expected on this branch.

compat: closing mercurial-3.6 compatibility branch The "evolve-6.0.0" release drop compatibility with Mercurial 3.6. No new commit are expected on this branch.

compat: closing mercurial-3.4 compatibility branch The "evolve-6.0.0" release drop compatibility with Mercurial 3.4. No new commit are expected on this branch.

compat: closing mercurial-3.5 compatibility branch The "evolve-6.0.0" release drop compatibility with mercurial 3.5. No new commit are expected on this branch.

README: timeless typo fixes This applies some feedback timeless provided me from IRC.

cleanup: drop an empty section header

compat: drop some <hg-3.4 compatibility code The `hg commit` commands has a -i flag for ages now.

README: more update to prepare for pypi upload * mention the evolve.serveronly extension, * remove help related to topic into a different README file.

evolve: update the capabilities and commands name for obshashrange We makes is clear that these version are useful for earlier testing but they are not ready for any kind of real usage yet.

README: more change to have a pretty rendering on pypi We moves section around and fixes some markup.

MANIFEST.in: fix various mismatch check-manifest is no longer complaining

README: rework install instruction For both evolve and topic. The topic introduction is updated too.

README: rework the intro Less scary wording (similar to the wiki changes) and point to the user mailing list.

rangeobshash: minor cleanup of the obshash code We achieved minor speedup by delaying the hashing until we know it is needed.

stablerange: remove call to 'repo.revs' It turned out that the percentage of time spend parsing the revset string was two digits, so we compute de heads inline.

stablerange: reuse node calculation as much as possible We have a property cache with that value, so we just reuse it.
