chgserver: add setumask method

Before this patch, the server won't inherit umask from the client, which
will fail test-inherit-mode.t. This patch provides a way for the client
to change umask of the server, similar to chdir and setenv.

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

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