remotenames: don't inherit the remotenames class from dict class The remotenames class was moved from hgremotenames extension. The class in hgremotenames extension used to extend dict because updating bookmark was done through a dict-like interface or Sean (smf) wanted it to be that way. But now, we can remove the inheritance from the dict class as updating bookmark is not done using a dict-like interface. Thanks to Martin von Zweigbergk for spotting this.

run-tests: cache hghave results Spawning a process on Windows is expensive. I've got a version of test-lfs-test-server.t locally which prints the http request/responses that totals 819 lines, with 149 conditional lines, 11 #if tests, and 2 test cases. It takes just under 1 minute with this change to run both cases, vs just over 2 minutes without this change. Worse, when I explored adding ui.debug to the test, it takes 13 minutes due to all of the mismatches and retests, vs less than 1 minute with this change. Overall, the difference when running all tests is negligible- 103 minutes with this change, vs 105 without when using -j9. It also looks like an exit value of 2 from `hghave` is treated specially, but there's nothing preventing 2 missing features from also using this value.

run-tests: resume raising an exception when a server fails to start Prior to 93228b2a1fc0, this exception was raised before the diff could be printed. By raising the exception after printing the diff, the location of the failure can be identified, but it is also easier to locate test runs where this occurs. The test bot maintains a list of failed tests, separate from the wall of diff output.

bookmarks: write bookmarks file deterministically Bookmarks are internally stored as an unsorted dictionary. Let's at least write out the bookmarks file in a deterministic order so it is easier to test, diff, etc. Differential Revision: https://phab.mercurial-scm.org/D2469

phases: write phaseroots deterministically self.phaseroots is a list of sets of binary nodes. Let's sort the nodes before writing so the phaseroots file is written out deterministically. Differential Revision: https://phab.mercurial-scm.org/D2468

internals: document bundle2 format It seems like a good idea to have thorough documentation of the bundle2 data format, including the format of each part and the capabilities. The added documentation is far from complete. For example, we don't fully capture the semantics of each capability and part. But a start is better than nothing, which was pretty much where we were before. Differential Revision: https://phab.mercurial-scm.org/D2298
