include: legacy header files from themwi-rtp-mgr
<themwi/rtp/pstn_defs.h> and <themwi/rtp/rtp_defs.h> will be
populated by both the present package and themwi-rtp-mgr.
Because of this duplicate definition, these two legacy headers
have to be treated as essentially immutable.
Why can't we drop these headers from themwi-rtp-mgr and make
the present package their new (and single) official home?
Answer: the present package depends on libosmocore, whereas
themwi-rtp-mgr does not. We already have some programs that
depend on themwi-rtp-mgr, use these headers, yet have no
dependencies on Osmocom.
