Previous patch added build support for ignore_suspend, however it should
be also possible to decompile binary back to human readable form and not
lose data.

XXX_VOICE_WAKEUP also known as 'ignore_suspend' is already processed by
kernel in soc-topology, but there is no way of setting it via topology
file like it's the case for other flags. Fix this by adding it to pcm,
dai and link parsing mechanism.

Clang 16 makes -Wimplicit-function-declaration an error by default

Use macro to maintain only one code. The status may be 0 or 1 - handle
both values correctly.
Also, fix the possible memory leak in snd_use_case_geti() - string
str should be freed even when the error is returned.

Right now in snd_use_case_geti you cannot tell if the item being queried
exists or not when being checked. This also means the only way to check
for the existence of something in the client of the library is to
iterate over the list of mods/devs even if we know exactly the name we
are looking for. We have functions that do exactly this internally so
lets return this information in a logical fashion through geti.
Also clean up some trailing white space nearby.

The previous fix in aa4f56c3 was not correct. The root of the cause is

The file type in the st_mode field is not encoded as unique bits but as
an enumerator. Checking if some bits of S_IFLNK are set does not work
correctly because it happens to evaluate to true for regular files as
well.
The POSIX man page suggests using the following approach to check
the file type:
if ((sb.st_mode & S_IFMT) == S_IFLNK)
Alternatively, there is a S_ISLNK() macro to check this more easily.
Make use of the latter so that readlink() is only called on actual
symbolic links and not regular files. This makes audio work again
with slightly older alsa-ucm-conf versions or alternative top-level
ucm.conf configurations that do not make use of symlinks.

PulseAudio and PipeWire seems to appear including careless code to
process events of mixer element in implementation of mixer class.
* https://lore.kernel.org/alsa-devel/YrbxZ2b+3rIdi7Ut@workstation/
They register own implementation of mixer class. At addition event,
they attach own mixer element into hcontrol element. However at removal
event, they never detach the mixer element from hcontrol element. They
hit assertion in mixer API internal due to unsatisfied postcondition.
This commit adds documentation about postcondition of removal event
processing so that developer for implementation of mixer class easily
realize the way to satisfy the postcondition.
