Adds a new config section that allows adjusting behaviour for certain
transcoding scenarios. This only adds the initial support for the config
option.

Special codec handler to support not forwarding (nor any processing
whatsoever) of particular payload types at all. Support this in the
kernel module as well.
Change-Id: If10227affa54307e1e9b448eadd0bf2bfc5774ba
Only use the codec handler's "kernelize" flag to determine whether a
particular payload type can be handled by the kernel or not. It's
supposed to be a reliable indicator, making checking the other flags
unnecessary.

Split function into one part handling the "target" (i.e. ingress)
portion of the forwarding chain, and one function handling just the
outputs.

Instead of explicitly triggering an update of subscribers for A and B
during an offer/answer, trigger it only for one side (A) and then
iterate through all subscribers and subsriptions and update them all.
This automatically triggers an update for B, as well as any other
existing subscriptions that might be affected. Use a monotonically
increading update iterator counter to track which medias have been
updated so we don't run into infinite recursion.

First step to refactoring the kernelize* functions. Keep all state in a
central struct that is passed to all functions. Requires an auxiliary
bool to facilitate a case distinction in kernelize_one, which can be
removed once refactoring is complete.

Obsolete the two flavours of packet_encoded_tx and instead distinguish
the two flavour of sequence number handling (passthrough and
self-generated) through a function pointer in the codec SSRC handler,
directly pointing to one of the two existing codec_output_rtp wrappers.

This seems to be an acceptable and reliable way to detect RTCP
multiplexed with RTP, even if `a=rtcp-mux` wasn't advertised in the SDP.
Take the opportunity to clean up __streams_set_sinks() a bit by giving
the variables better names.

Use the correct media object (the source media) to obtain media-level i=
lines from. Adapt OSRTP output function to do the same.

... and allow non-existing HT during lookup. Also reorder cleanup
sequence. This makes managing subscriptions in codec handlers possible.

Separate out the two distinct use cases of requesting a specific port,
and requesting (one or more) random ports.
Change-Id: Ifbe7725d8638d49f620c9f4b9445342d180c8770
Add helper functions wrapping around reserve_port which directly return
a socket_port_link object. This allows us to rework
__get_consecutive_ports and release_reserved_port to eliminate mixing
different port numbers in the same list, which makes for cleaner code.

Empty subscriptions are not supported and would be an internal bug.
Remove expectations that the contents can be NULL.

This flag is relevant to copy the state from A to B during an
offer/answer. It should only be set on one side, not on both.
Change-Id: Ie5c6de58a4ca11b37526b719b1937ffb08ebf512
Have one function to just set flags and init a single media, and another
one to set up sink pointers
Change-Id: I3207ea9f36a0e3575c2149e077e6106fd065fe1b
Directly return the just-created subscription from the respective
function. Saves a hash table lookup.

Turns out that g_ptr_array_new_full or g_ptr_array_new_sized only
preallocates array members, but doesn't set the length.
Change-Id: I722e29a13c415f2a5ff62830dce60205f273b445
Grab source monologue and source media only once, and pass the object
down to the various functions, instead of doing the retrieval several
times in multiple places.
Change-Id: I88d019dbf9493fa0037161390fdb9efda58f5441
We know whether we're printing for monologues or for medias, so there's
no need to have a generic function signature.
