Since complete sound frame is already available, just write it out to
pulseaudio stream using more efficient pa_stream_begin_write API.
This removes a few milliseconds of pure wait time from each play call and
makes audio playback a bit smoother.
C requires prototypes or compilers will complain about them missing. Our
library entry points do not have such, therefore add the macro
FREERDP_ENTRY_POINT which declares the function prototype automatically
before the function.
due to the nature of the sound channel there are multiple listeners
waiting for the server to open the channel and most of them are called
by the server. Only open the channel once.
Most dynamic channels share the same copied and pasted code for the XXX_CHANNEL_CALLBACK
and XXX_LISTENER_CALLBACK types. This patch introduce GENERIC_CHANNEL_CALLBACK and
GENERIC_LISTENER_CALLBACK that fits for most channels and discard custom type definitions.
Currently, all FreeRDP-based clients don't send any WaveConfirm PDUs
for received samples, when using a dynamic channel for audio output
redirection.
[MS-RDPEA] 2.2.3.8 Wave Confirm PDU mentions, that a WaveConfirm PDU
MUST be sent, when a WaveInfo PDU + Wave PDU, or Wave2 PDU is received
and when the audio data sample is emitted to completion by the client.
The first WaveConfirm PDU is used by the server to determine the
network latency and the second WaveConfirm PDU is used by the server to
determine the render latency.
So, fix the current behaviour, where FreeRDP currently does not send
any WaveConfirm PDU, when using the dynamic channel, or only sends one
WaveConfirm PDU for the sample.
For the first WaveConfirm PDU, use the same timestamp, that was
included in the first WaveInfo/Wave2 PDU.
For the second WaveConfirm PDU, add the render latency on top of the
arrival timestamp.

Building client channels out of tree does not work reliable as the
dependencies can not be easily split. (exceptions may be simple ones
as echo channel)
It does complicate the build system and code though, so remove this
for maintainability reasons.
