566050 - Make runxpcshelltests.py tests more amenable to non-standard debugging scenarios

Status: RESOLVED FIXED

(Testing :: XPCShell Harness, enhancement)

Description

[Chris Jones [:cjones] inactive; ni?/f?/r? if you need me]

Today I wanted to debug some xpcshell tests in the following ways

 - see stdout/stderr spew from multiple tests (MOZ_IPC_MESSAGE_LOG)
 - see IPC log spew for just one test
 - run valgrind on multiple tests and see all output
 - same, for one test
 - interrupt the test harness after a bug is observed

The attached patch makes these easier for me by

 - having |make check-one/xpcshell-tests| honor EXTRA_TEST_ARGS
 - honor a --verbose flag that doesn't suppress stdout/stderr spew, make it default for check-one
 - restore SIG_DFL semantics for SIGINT

I'm ok with everything but the SIGINT change, unless you get jduell to sign off on it (since he's the one who added it).
