This updates the g1 code to create the GAtChat object in the enable() callback,
and to unref it in the disable() callback. This is more in line with what
the other plugins do, and as a bonus fixes a segfault when powering down
the G1 modem..

The G1 doesn't support mode2, despite advertising it.
The G1 chokes w/ an "Error 303" when we specify NMI mode 2. Adding a
quirk to drop that mode from the supported list (just use mode 1) allows
the G1 to properly deal with SMS.
This is based on the generic_at parser, with unnecessary stuff removed.
The G1 routinely screws up CRLFs, so the parser needs to account for
that. This parser ignores leading CRLFs (which is what reference-ril
does as well), as well as trailing LFs (which are sometimes left out).
CRs are used as end-of-message indicators. Since we're not bothering
tracking CRLFs, there's also no need for a GARBAGE state, or MULTILINE
stuff.
G1 plugin is based on generic_at, with a bunch of stuff dropped
and simplified. We use AT+CFUN=1 for powering on rather than having
a configurable init string. We also manually set the default state
during init (the G1 appears to start in mode V0 by default). The
device (/dev/smd0) is hardcoded.
