perf: make perf.run-limits code work with Python 3 We need b'' because perf.py isn't run through the source transformer. We need to cast the exception to bytes using pycompat.bytestr() because ValueError can't be %s formatted due to built-in exceptions lacking __bytes__. We need to pycompat.sysstr() before the float() and int() cast so the ValueError message doesn't have b'' in it. Even with that, it looks like the error message for the ValueError for float casts added quotes, so we need to account for that in test output.

localrepo: rename crev in _filecommit() to cnode, since it's a node I know we often use "rev" generically, but here's it always a node, so it helps to be specific. Differential Revision: https://phab.mercurial-scm.org/D6181

tests: unset environment variable P in test-revset2.t (issue6109) The test tests/test-revset2.t fails the test case "Test repo.anyrevs with customized revset overrides" (line 1609) if the environment variable P is set. The test implicitly expects that the environment, in which it is started, does not export the variable 'P'. To solve this issue, unset 'P' right before the test commands are run.
