Ensure the SND_CTL_TLV_DB_GAIN_MUTE value is returned when the calculated
gain equals the minimum dB value for the SNDRV_CTL_TLVT_DB_MINMAX_MUTE type.
The previous check based solely on the volume value could miss cases where
the linear calculation resulted in the minimum gain.

It is necessary to reset the state logic before each verb variant
is parsed. So save the original variable list and macros and
restore them before each parser iteration.

This reverts commit ddfc32abf5.
It was not a correct fix. The private values may differ (multiple
instances for e.g. USB sound cards). This fix prevents to load
private configurations for other instances.

snd_pcm_avail_delay() is expected to report avail and delay values
in atomic fashion. However the function does two separate syscalls
and it cannot guarantee the avail value is the same as was used
to calculate the delay. This is a problem as the reported delay is
always relative to avail frames value.
If application (like e.g. alsa_conformance_test) uses snd_pcm_avail_delay()
to estimate the effective play position, it can observe bogus delay
values (and effective play position going backwards) if
snd_pcm_avail_delay() is called during a DMA burst where hw_ptr
moves quickly.
This commit adds a loop similar to that used in snd_pcm_hw_htimestamp()
to wait until we get a stable avail reading, and only then extract
the delay. This will avoid bogus values if function is called during
DMA bursts.

When the first client of plugins such as dshare open the hw device they set
a default tstamp_type in snd_pcm_direct_initialize_slave based on
tstamp_type from the config file. But when subsequent clients open the same
plugin the snd_pcm_hw_open_fd function clobbers this default.

Install of the alsalisp binary has been disabled since 2006 (in commit
8d382ccd), and building of it was disabled by default in 2018 (in commit
32ceab21), so it is reasonable to assume that nobody is using it.
Use within the alsa-lib project is limited to an aliases file that looks
like it is intended as an example, plus some very small .alisp files
associated with the SiS SI7018 PCI sound card which has not been
manufactured in years. These too have not been installed since 2018 when
commit 32ceab21 disabled building of the alsalisp binary.
In preparing this change, I searched the Github issue tracker for
"lisp", "alisp" and "alsalisp", and found no complaints about the above
changes. I also did a Github code search for projects that might be
including the `alisp.h` header and found none. Therefore I think this
code can be safely deleted and nobody is likely to object.

The values SNDRV_XXX are used incorrectly in some code where they
should have been SND_XXX, due to copy&paste from the kernel code.
Practically seen there are no difference, and the code still works
fine, but those should be corrected for consistency.
