Initialized "cgmi_retries" variable from CustomInitContext with the
same value as the other retries, moreover the context is now allocated
with g_slice_new0.
Before this changes, when cgmi_retries assumed big values during the
probing of no AT-capable ports, the command AT+CGMI (mm-plugin-dell.c:custom_init_step)
was sent a semi-infinite number of times, blocking the plugin's initialization.
For Dell-branded Novatel, Sierra and Ericsson modems.
The Novatel plugin will no longer accept every Dell-branded modem, which was
the current situation. Instead, a new Dell plugin will take care of probing for
the correct vendor string, and based on the results create a specific Novatel,
Sierra or Ericsson modem.
In order to properly support this, the Novatel, Sierra and MBM plugins now
export their implementations into non-inst libraries that the Dell plugin will
import.
Also, for now, the Dell plugin doesn't make any difference between e.g. Sierra
or Ericsson MBIM implementations, just a generic MBIM modem is created in both
cases, as that is anyway what the Ericsson MBM and Sierra plugins do already.
