The size argument is wrong for one of the snprintf() calls in
snd_pcm_chmap_print(), allowing an overflow to happen (the user-provided
buffer may be written data up to 2x its actual size).

The compiler warns like:
main.c:1664:9: warning: 'err' may be used uninitialized in this function [-Wmaybe-uninitialized]
and actually there are slight code paths that slip.

a combination of some of the following garbage collecting LD/CFLAGS
-Os -g0 -fdata-sections -ffunction-sections -s -Wl,--gc-sections
-fno-unwind-tables -fno-asynchronous-unwind-tables
causes the symbol versioning marker symbols to be removed from BSS
since they're otherwise unreferenced. this causes dlsym failing to
find them which results in runtime breakage:
$ alsamixer
ALSA lib dlmisc.c:142:(snd_dlsym_verify) unable to verify version for symbol snd_config_hook_load
ALSA lib conf.c:3328:(snd_config_hooks_call) symbol snd_config_hook_load is not defined inside (null)
ALSA lib conf.c:3788:(snd_config_update_r) hooks failed, removing configuration
cannot open mixer: No such device or address
correct DSO:
$ objdump -T libasound.so.2.strip | grep _snd_config_hook_load_dlsym_config_hook_001
001196bc g DO .bss 00000001 _snd_config_hook_load_dlsym_config_hook_001
incorrect DSO:
$ objdump -T libs/libasound.so.2 | grep _snd_config_hook_load_dlsym_config_hook_001
00000000 g DO *ABS* 00000001 _snd_config_hook_load_dlsym_config_hook_001
since alsa was built with --without-versioning, doing those versioning
checks at all is unnecessary and harmful and thus now disabled in this case.

When a slave PCM gets an error like XRUN, it stops and notifies with
SND_TIMER_EVENT_MSTOP event. But the current code filters out this
type and eventually hang due to the empty timer queue. The fix is to
just add this event type to the filter bit mask.

The current behavior of snd_pcm_rewindable and snd_pcm_forwardable means
that the returned value is only accurate to one period. Or maybe even
meaningless if period interrupts are off. Fetch the up-to-date position
of the hardware pointer, as that's what is wanted by callers.

Such negative returns are possible during an underrun if xrun detection
is disabled.
So, don't store the result in an unsigned variable (where it will
overflow), and postpone the trigger in such case, too.

Such negative values can happen when an underrun happens and xrun
detection is disabled. Another situation is if the device updated the
pointer before alsa-lib has a chance to detect the xrun.
The problem is that these negative values could propagate to the
snd_pcm_rewindable return value, where it is specified that negative
returns must be interpreted as error codes and not as negative amount of
samples.

There are a few places where the argument of the .rewind or .forward
callback is checked against the same value as returned by .rewindable or
.forwardable. Express this "don't rewind more than rewindable" logic
explicitly, so that the future fixes to the rewindable size can go to
one function instead of two.
While at it, take advantage of the fact that snd_pcm_mmap_avail() cannot
return negative values (except due to integer overflow, which is AFAICS
impossible given the current boundary choice).

This function returned incorrect results when hw.ptr was near the
boundary and hw.appl_ptr was near zero. Here "incorrect" means "greater
than the boundary".
The result was incorrect, because it was used as a return value of
various *_rewindable() functions and also as the delay for ioplug.
