Complete overhaul of the codec handling code:
*) obsolete flags `asymmetric codecs`, `symmetric codecs`, `reorder
codecs`
*) support proper codec offer/answer
*) split codec manipulation (strip/offer/accept/etc) into separate
functions for clarity and better code maintenance
*) fully update codec handlers in both directions after an answer
*) explicit allocation and handling of codecs and payload types in a
codec_store object
*) improve codec matchup logic during answer
*) more explicit handling of supplemental codecs (CN/DTMF)
*) remove now obsolete hacks for handling certain use cases

If we receive an SDP with a DTLS fingerprint, by default we adopt the
hash function used for that fingerprint in subsequent communication with
that peer. However, if the SDP is an answer, and we previously used a
different hash function in the offer towards that peer, then a later
re-invite offer would be sent with a different fingerprint, causing an
unexpected DTLS restart. Instead, make sure we don't change fingerprints
if one was already sent.

Whether a bit-field is signed or unsigned is implementation specific, so
we should be explicit about this.

While these usages are not supposed to be security sensitive, it's still
best to avoid the usage altogether so that we do not need to think about
it. Add a taint macro so that this does not regress in the future.

Link the attribute value to each RTP payload type and only output it if
PT is still present
Also merge PT attribute printing into a single loop

add explicit flag for fingerprint length instead of using the hash
function

To avoid repeated strcmp()s and make use of switch()'s optimised binary
lookup, we employ a second build step that preprocesses certain .c files
and uses gperf to substitute pseudomacros with their respective constant
hash value.

crypto containing padding should be sent within sdp for pass through
Change-Id: I1f7502f34e9492100e5c3a5a7345319ed996c22c
We should offer all crypto suites that we support. If passing through
SDES, we should amend the list of crypto suites with all additional ones
that we support that weren't included in the received offer.
