Philipp Maier ec967d74f7 Revert "mgcp_codec: do not differentiate between oa and bwe when comparing codec" 
This reverts commit e0058b7207. The reason
for this revert is that the solution in the reverted patch does not
cover a situation where the other side announces both payload formats at
the same time.

It could be that the end facing to a transit network announces both
formats under two different payload types. In this case no conversion
would be necessary. Depending on the input format the output would be
send to the transit network under the payload type that matches and no
conversion would happen at all.

This revert re-intruduces the problem that was fixed in the patch
before. Therefore it must be merged together with the follow up patch
(Ifbd201a2749009a4644a29bd77e1d0fc0c124a9d) that contains the proper fix.

About OsmoMGW
=============

OsmoMGW originated from the OpenBSC project, which started as a minimalistic
all-in-one implementation of the GSM Network. In 2017, OpenBSC had reached
maturity and diversity (including M3UA SIGTRAN and 3G support in the form of
IuCS and IuPS interfaces) that naturally lead to a separation of the all-in-one
approach to fully independent separate programs as in typical GSM networks.

OsmoMGW was one of the parts split off from the old openbsc.git. It originated
as a solution to merely navigate RTP streams through a NAT, but has since
matured to a Media Gateway implementation that is capable of streaming RTP for
2G (AoIP) and 3G (IuCS) GSM networks as well as (still not implemented at time
of writing) transcoding between TRAU, various RTP payloads and IuUP.

The OsmoMGW program exposes an MGCP interface towards clients like OsmoMSC and
OsmoBSC, and receives and sends RTP streams as configured via MGCP.

The libosmo-mgcp-client library exposes utilities used by e.g. OsmoMSC (found
in osmo-msc.git) to instruct OsmoMGW via its MGCP service.
