pseudomodem: Run pseudomodem in a separate subprocess.
This CL cleans up the way pseudomodem is launched. The main changes are:
- |pseudomodem.py| no longer tries to fork pseudomodem in a background
process. It is now a top level package that runs pseudomodem in the current
process. This should no longer be used directly.
- |pseudomodem_context.py| should be used by tests. The companion module
|run_pseudomodem.py| should be used to run pseudomodem from the command
line. This cleanly launches pseudomodem in a separate process. It also
provides ways to customize the pseudomodem with the same flexibility as
before this CL.
- Logs from pseudomodem are now directed to syslog, and are handled in the
same way as ModemManager logs. Additionally, logs can be directed to stdout.
- pseudomodem now runs as the 'modem' user -- this is the user that
modemmanager runs as.
BUG=chromium:328257
TEST=(1) Run
/usr/local/autotest/cros/cellular/pseudomodem/pseudomodem_context.py
with and without the '--cli' option and ensure pseudomodem works as
expected in standalone mode.
(2) After fixing tests (see companion CL:184088), run network3g_pseudomodem
and network_ui test suites.
