copyfile: add an optional parameter to copy other stat data Contrary to the comment, I didn't see any evidence that we were copying atime/mtime at all. This adds a parameter to copyfile to optionally copy it and other stat data, with the default being to not copy it. Many systems don't support changing the timestamp of a symlink, but we don't need that in general anyway -- copystat is mostly useful for editors, most of which will dereference symlinks anyway.

tests: move the '-hg' postfix for all style tests We had them on 'test-check-code-hg.t' to avoid collision with the test checking 'check-code' itself. Now that this one have been rename, we can safely remove this suffix for all of them. This get them in line with 'check-pyflakes.t'.

test: rename 'check-code' own test to 'test-contrib-check-code.t' This test (making sure the 'check-code' script run as intended) have been confused with the test making that the mercurial code base comply with our coding still by multiple generations of contributors. We are moving it out of the way so that all tests starting with 'test-check' are now doing compliance testing.

parsers: add a missed PyErr_NoMemory

parsers: check results of PyInt_FromLong (issue4771)

parsers: simplify error logic in compute_phases_map_sets Since Py_XDECREF and free both accept NULL pointers, we can get by with just two exit paths: one for success, and one for error. This considerably simplifies reasoning about the possible ways to exit from this function.

util: rename argument of isatty() In general, "fd" is a file descriptor, but isatty() expects a file object. We should call it "fp" or "fh".

posix: remove unixdomainserver class It's no longer used since the removal of the inotify extension.
