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.

largefiles: document behavior of caching largefiles for new heads

check-code: add Makefile target to run check-code

byterange: remove now-unused sys import
