amend: update .hgsubstate before committing a memctx (issue5677)

This is a minimal copy of localrepo.commit(). As the current amend() function
heavily depends on the wctx API, it wasn't easy to port it to use a separate
status tuple. So for now, wctx._status is updated in-place.

# showstack.py - extension to dump a Python stack trace on signal

# binds to both SIGQUIT (Ctrl-\) and SIGINFO (Ctrl-T on BSDs)
