[PATCH] libosmocore[master]: AMR: add function to check speech frames

[Max]

Hello Harald Welte, Jenkins Builder,

I'd like you to reexamine a change.  Please visit

    https://gerrit.osmocom.org/959

to look at the new patch set (#2).

AMR: add function to check speech frames

Add convenience function osmo_amr_is_speech() to check if given AMR
frame is speech frame: non-speech frames often require special
processing.
