tests: make test-convert-bzr.t more stable The test would occasionally fail because datesort don't have sub-second granularity and thus can't sort commits made in the same second. The test is made more stable by adding 1 second of sleep to make sure the bzr commits are done with different timestamps.

casecollision: add tests Add more tests to exercise the case collion detection code

dirstate: add dir/file collision test Add a test exercising collisions in add between files and directories of the same name.

dirstate: factor common update code into _addpath Factor update code common to all callers of _addpath into _addpath. By centralizing the update code here, it provides one place to put updates to new data structures - in a future patch. It also removes a few lines of duplicate code.

test-subrepo-relative-path: partially adapt for Windows

tests: make rm of usercache in test-largefiles.t more robust Recursive removal of a different path could be fatal - better avoid recursive rm completely.

tests: enable test-largefiles.t on Windows MSYS The 'serve' requirement is moved to the sections that really need it. $USERCACHE needs quoting.

test-largefiles: partially adapt for Windows The adaption is partial, because "serve" is not yet officially supported in tests on Windows. The test passes on Windows with an experimental testbed that supports hg serve in tests on Windows - except for some USERCACHE issues. The added (glob)'s are needed because of backslash <-> shlash issues in paths.
