GLIBC is not necessarily the only library that provides execinfo.
With libexecinfo execinfo can be used also in other Libraries.
The patch lets the configure check the existence of the header
and the libexecinfo Library and uses them if avaible.
(also fixes compilation if execinfo is not avaible)
Implements a sim auth driver that communicates with ofono to handle
GSM/UMTS authentication algorithms. This plugin takes care of
disovering ofono, the modem, IMSI, and SIM capabilities i.e. what
algorithms are supported.
Provides a driver for hardcoding EAP-SIM/AKA keys. The driver
expects the environment variable IWD_SIM_KEYS to point to a
valid config file with IMSI, Kc, SRES for SIM or IMSI, KI, OPC,
AMF for AKA. To use this driver '--plugin=sim_hardcoded' must
be supplied when IWD starts.
