Adds support for the Huawei E3276 by sending the shortened form of the
AT^NDISDUP command where possible, as the E3276 fails with an '+CME ERROR:
Incorrect parameters' if encoded_auth is set to 0. This behaviour is slightly
different to the E1820 and K4605 (E372) which will happily establish a
connection with encoded_auth set to 0, 1 or 2.
The QCDM port commands are never cached, so remove the option from the command()
method. Will also simplify command caching afterwards as it will be an AT-only
thing.
The new PHS8 or PXS8 devices may expose multiple tty ports, but only one is
supposed to be used for PPP. So, query which port that is and flag it before
grabbing it in the modem.
When I use clang 3.5 to build it, I got

Make sure we cleanup the 'buffer-full' signal handler when moving from AT
probing to QCDM probing, so that we don't try to remove a signal handler from
a QCDM port in which we haven't set it.
E.g. avoids:
