AT%SPVER: new command for setting custom speech version lists
The speech version list in the Bearer Capability IE tells the network
which speech codecs are supported by the MS, and in which order of
preference. The standard behaviour is to list all codecs that are
supported by the hw+fw platform, and the standard preference order
is newer over older, FR over HR. But sometimes it is desirable
(for network testing) to artificially restrict which codecs the test MS
will declare as supported, and/or to list them in some peculiar
non-standard order of preference. Add a new private AT command,
AT%SPVER, allowing the user to set and clear custom speech version
lists for the Bearer Capability IE composer in CC.
