* Added transport_get_context to get rdpContext in IO callbacks.
* Added WINPR_ASSERT where possible.
* Fixed handle count mismatch in transport_get_event_handles
* Split out proxy headers and moved to public API to allow external
modules to be built.
* Split proxy into proxy library and proxy binary. The library
can be used by other applications and provides a simple API
* Improved channel passthrough, now all channels including dynamic
channels work.
* Extended module API to hook more events, improved module samples
* Cleaned up proxy code, removed global static variables used,
added WINPR_ASSERT
* Added transport_get_context to get rdpContext in IO callbacks.
* Added WINPR_ASSERT where possible.
* Fixed handle count mismatch in transport_get_event_handles
RDPSND channel is special, as it has many names.
(e.g. static channel, dynamic channel and UDP one.
Use RDPSND_CHANNEL_NAME to identify the module name instad of
RDPSND_DVC_CHANNEL_NAME
* Use freerdp_settings_* for shadow and sample server
* Added freerdp_peer_set_local_and_hostname
* Code cleanups and WINPR_ASSERT
* Code cleanups
* Use CHANNEL_NAME_LEN where appropriate
* Use temporary variables in loop instead of direct array access
* Fixed research for native PCM format
* Fixed compatibility detection for resampling
* dsp: Makes channel mix and encoding process use separated buffers
* Give FramesPerPacket to freerdp_dsp_context_reset function
* dsp: Fix DVI_ADPCM codec by respecting the required packet size
* Forbid mono channel in macos
* Fix audin command line channel option
* Disable ADPCM codec as it does not work
* Refactor valid native codec research
* Native codec research: Try different channels number
* Fix dsp channel mix
* Fix dsp resample
* Added new function pointers to cancel a pending operation
* Added new function pointers to send custom event flags
* Added exposed feature mask to disable channel features
