tests: python executable should always be globbed Similar to 4d93d73b8aec, the python executable could be python2.X, Python, pypy, or maybe something futuristic like pyston or nuitka.

setup: add missing hgext.fsmonitor Before this patch, fsmonitor was not installed along with other extensions. It did correctly build the C files needed but forgot to copy over the python files. This patch fixes it by adding fsmonitor and fsmonitor.pywatchman to the correct install variable.

dispatch: show deprecation warning if command has no attributes (issue5137) norepo/optionalrepo/inferrepo were removed by aa73d6a5d9ea, which would be significant API change. This patch tries to avoid crash even if ancient third-party extensions are enabled.

dispatch: extract function that tests command attributes This function will host the compatibility layer for old third-party commands. See the next patch for details.

dispatch: make cmdalias forward command attributes to function This delays resolution of command attributes so that missing attributes can be warned only when necessary.

run-tests: use different chg socket directories for different tests Before this patch, if --chg or --with-chg is specified, all tests are using the same chgserver socket. Since the chg client holds a lock when it starts a new server, and every test needs at least a new chg server due to different HGRCPATH affecting the confighash, the result is a lot of tests will be timed out if -j is large (for example, 50 or 100). This patch solves the issue by using different chg socket directories for different tests.
