If we're updating the handlers for one particular source -> sink flow,
only stop/reset the handlers matching this flow.

previously, dtmf_inject wouldn't add the events as the dtmf_payload_type
was set to -1 as part of the delay buffer handling. However, as we
know we want this DTMF, this change updates the function to check for
and use the real_dtmf_payload_type value
Then, in codec_add_dtmf_event, we can check the injected bool and
if set, use the real_dtmf_payload_type again to decide whether to
push the event onto the queue

This HT is needed when updating UDPTL/T.38 handlers, on both sides of
the call. Make sure the HT exists.

When we're duplicating the packet contents, we must also update the RTP
header pointer accordingly.

Transcoding is flow-specific, so it doesn't make sense to have a flag
for it in a call_media section. Instead we use the transcoding flag set
on the call_subscription objects (on subscribers), and set/unset a flag
on the monologue struct, depending on whether any media flows (going to
subscribers) have transcoding enabled.

Pass the subscription object to codec_handlers_update to eliminate the
need for a return type and the subsequent if/else.

Simply stripping a supplemental codec doesn't actually affect the
remaining real codecs. Add a special-cased version of codec_touched() to
ignore such a manipulation.
Add a matching test case.

Don't try to interpret or schedule DTMF packets if we're just doing RTP
passthrough.
Without tracking the seqencing and timestamping of the primary media
stream, we cannot actually schedule DTMF packets properly. Use the
presence of a defined output sequence number to make this determination.
The other case that uses a predefined output sequence number is when
media is coming from a pre-coded media player stream. The same thing
applies: These packets are already scheduled, so we can skip trying to
schedule them again.

This replicates the code to replace audio packets with injected DTMF
events. Unfortunately the code paths between forwarding audio and
processing/forwarding DTMF events is quite different, so some slight
duplication is needed.
Additionally the case of blocked DTMF + injected DTMF must be handled.

Add special return value to indicate that an event was a duplicate and
should be discarded.

Add a flag to inhibit kernel mode while DTMF injection is active. Tie in
DTMF playback trigger function: Remove stream from kernel, set inhibit
flag, play DTMF, then unset inhibit flag when all events have been
injected.

Support using the SSRC TS derived from received RTP packets as "encoder"
TS (the "next" expected TS) for passthrough RTP in addition to the FIFO
TS of an actual encoder.

Make the decision whether or not to use SSRC passthrough handlers in the
upper level calling function, instead of implicitly in
__make_passthrough_gsl()
Change-Id: Ied88120ea4f12d50e3c5afb96023bdd86c42c6e1
__make_passthrough_ssrc() is only used after a passthrough handler has
already been created via __make_passthrough(), and the two functions do
exactly the same thing other than using a different handler functions.
So we can skip completely shutting down the handler and creating a new
one, and only update the handler function instead.

Instead of just setting the "force transcoding" flag when DTMF injection
is required, check it on a per-codec basis, so we can be more granular
with this decision.
Functional no-op.

Using a pointer array instead of a linked lists allows us to directly
reference a media section by index number, without having to spool into
the linked list.
No functional changes.

Track audio writes in the mix buffer to set the `active` flag to true
whenever a write occurs, which makes it possible to create the buffer in
an inactivate state and implicitly set it active on demand.
Handle the mix buffer not returning any data in the RTP sending logic
(which is what happens for an inactive buffer) by simply not sending any
packets.
