Cross-compilation failing due to make library resolution.

Plugin support
|
|
Update the mixer framework to support plugins. Add ability for physical
card to have either kernel registered mixer controls or plugin
registered mixer control or both. Split mixer controls into two groups,
one for kernel registered (hw_grp) and the other for plugin registered
(virtual_grp).

Update the pcm framework to support plugins. Resolve the pcm device node
to be either kernel device or virtual device and setup function pointers
accordingly. Implement framework functionality for pcm_plugin.c for ease
of plugin development. Plugin itself is compiled as shared object (.so)
and dynamically linked from pcm_plugin.c.

pcm: Set SW params.avail_min to period size
|
|
Using MMAP APIs, this parameter wake up application
when 'avail_min' samples are availables.
When audio processing expects exactly a full period size samples,
the default parameter to 1 burns CPU until the full period available.
Fix SW params.avail parameter to period size value.

This allows starting capture from another thread.

Easier Version Specification

pcm: Remove setting unnecessary parameters

SUBFORMAT is always zero.
SAMPLE_BITS and FRAME_BITS are refined by ALSA based on the
already set FORMAT and CHANNELS.

This commit moves the changelog version check to the CI instead of the build
systems. Rationale is: the failure to update the changelog is not a build
failure / issue but rather an integration failure and it should be detected at
integration testing. The closest to integration testing is the CI testing which
is mandatory before pull requests and new features integration.
Additionally, the old version.py script is removed because it is relying on the
old version of include/tinyalsa/version.h where the TINYALSA_VERSION_STRING
macro is defiend as an explicit string literal. Since now the version string is
defined piece-wise and based on the individual version numbers, and since the
introduction of version.sh and its use within meson build system to get the
version from the version file, the old version.py script is obsolete.

Group read/write transfer into pcm_rw_transfer().
Create pcm_generic_transfer() for read/write and mmap
transfer modes. This recovers from xrun and suspended.

A generic transfer function will be created. Put together
functions related to it.

It is not needed.
As the pcm structure is opaque to user it can be safely
removed.

Make pcm_mmap_transfer() compatible with read/write IO.
start_threshold check was not valid for capture.
pcm->running checks were removed.
NOIRQ fallback was removed. Clocks of sound devices may
differ from the system, leading to desynchronization.

Instead of sending appl_ptr and avail_min to the kernel,
get them. This is the behavior of alsa-lib.
