Some codecs need the MTU as a parameter so wait until we acquire
with creating the codec context.
Make some method to enumerate the parameters from the transport
config and use that for the EnumFormat param.
Use codec methods. Init codec at start.
Remove rate match until we actually implement this
Add some buffering of packets before we hand them out.
Always simply fill a buffer and hand it out.
don't emit signals when we are following another driver.
Acquire transport as soon as it goes to PENDING.
Make the list of supported codecs available.
Register all supported codecs endpoints
Find the codec from the endpoint name
Put the codec on the transport for the sink to find.
Continue processing the input data until we can't send anymore. When
we are following another driver, we need to process each buffer in
the cycle completely or we will start lagging behind.
sbc_encode() can only process data with at least this->codesize bytes.
When encode_buffer() is called with less then codesize bytes, accumulate
those bytes in a temporary buffer up to codesize length, then SBC encode
them.
Maximum size for SBC buffer is (subbands * blocks * channels * 2) with max
subbands = 8, max blocks = 16, max channels = 2, i.e. 512.

Don't just remove the buffer from the queue when it was only
partially written. To do this, return the error code from add_buffer
and only remove the buffer when there is a real error.
This is more in line with wayland and it allows us to create new
interfaces in modules without having to add anything to the type
enum. It also removes some lookups to map type_id to readable
name in debug.
Remove the CAN_USE_BUFFERS flag, it is redundant. We can know this
because of the IO params and buffer params.
Add flags to the port_use_buffer call. We also want this call to
replace port_alloc_buffer. Together with a new result event we can
ask the node to (a)synchronously fill up the buffer data for us. This
is part of a plan to let remote nodes provide buffer data.
Define a set of standard factory names and document what they
contain. This makes it possible to change the implementation by
mapping the factory-name to a different shared library.
Move the epoll functions to the system functions and make the loop
use those. Use simple mask for events instead of enum.
Add the used system api in pw_loop.
Add System API to spa_support and use it where possible.
Pass the system API used in the realtime loops in spa_support as
well and use this in the realtime paths.
Improve bootstrapping, load only the log and cpu interfaces because
those can/need to be shared between instances. Let the core load
the other interfaces.
Add keys to configure the System and Loop implementations used in
pw_loop.
Pass a factory_name in the object_info of monitor and device.
Restructure the factory name to mean something functionaly. With
the factory to library mapping this then means that the implementation
of certain factories can be configured in the config file.
