Subject: - use talloc (of samba project) to debug memory allocations and
 simplify code - introduce new ucmd_alloc() function - add DTMF support to
 gsmd, libgsmd and gsmd-util - fix crash of libgsmd when events don't have
 handlers registered - implement call progress for TI modem - split modem init
 string in separate commands to fit our parser
