The system sku is used in SOF machine drivers to set specific quirks,
expose it in alsa-info to help support users. Example on a SoundWire
enabled device:
cat /sys/class/dmi/id/product_sku
0A32
dmidecode -s system-sku-number
0A32
Add a variable and expose the results of both methods.
Note that the dmidecode support is very recent and might not yet be
available in all distros:

This patch changes the way aborted stream is being saved. Currently when
abort signal happens the write back of read samples is skipped but there
is no reason to not save them. Also, we need to know how much frames have
been read and write only those.

This patch changes the logic of pcm_read() when abort signal has been
detected. During such condition we should return the amount of frames
actually read instead of the size requested by caller.
Currently functions pcm_read() and pcm_readv() when aborted (in_aborting
flag set) return the amount of requested frames instead of those actually
read prior to interrupt. The consequence of this is repetition of recent X
frames where X stands for amount of frames in one period. This problem is
barely visible or rather audible when the period is small like few
milliseconds because repetition of 1 [ms] of data is not-noticeable
however if we use buffer and period sizes in seconds then the problem
becomes apparent.

The silence frames generation in xrun_sync() seems to be currently
a bit off as snd_pcm_format_set_silence() uses a wrong buffer address
and size for zero-ing out the data. Consequently instead of clearing
out the last frame(s), snd_pcm_format_set_silence() ends up silencing
samples somewhere else in the buffer. This is partilarly more obvious
for higher frame sizes (e.g. more than 2 channels).
This patch fixes this issue by correcting the parameters passed to
snd_pcm_format_set_silence().

If we use 'alsaucm -n -b -' with 'get "CapturePCM/Internal Mic"' then
the alsaucm will report error and stop immediately. The reason is that
the parse_line in usecase.c appends an empty argument if a command ends
with quotes.
This change adds a patch to fix the parse_line function in usecase.c.

- Words in a command name don't have a fixed order (toggle_mute is the
same as mute_toggle)

This commit is a preparation for the configuration file parser.
The `int attr_*` variables have been moved into a separate struct.
Members of that struct are alphabetically ordered, so an attribute can
later be accessed by its name.
Added `int get_color_pair(short fg, short bg)` for returning or
creating a color pair number.
Added call to `use_default_colors()` for enabling access to the
terminal's default color (-1).

Mouse support has been added for mixer_widget.c, card_select.c and
proc_files.c.
In the mixer widget the mouse is handled as follows:
- After an element has been printed in mixer_display.c, a call to
clickable_set() will store the coordinates of the drawn area plus the
command enum that should be executed on click. An optional argument
holds an index which points to the selected mixer control.
- on_mouse_click() searches for a matching rectangle, focuses the mixer
control and returns the command enum.
In the menu widgets, the menu_driver() function handles mouse input.

This commit is a preparation for making keybindings configurable.
The hardcoded keys in the switch statements of mixer_widget.c,
textbox.c, proc_files.c and card_select.c have been replaced by
command enums. The command that shall be executed is looked up in
the arrays `mixer_bindings` and `textbox_bindings`.
The channel_mask enum has been made public, since LEFT and RIGHT are
used as command arguments in bindings.c.

In commit "ae9ddeb63443cc2c46e0f0b915466cca0f800372" the rint() was
changed to ceil(). Revert it back. The rint() rounding is more precise
for most cases.
Also, handle the special case where the percentual value is greather
then zero. Set the min + 1 value in this case.
At last, fix the return value in convert_prange() when range is zero.

As man page says: "If successful, the sched_setparam() function shall return zero."
Without update I got this output in the syslog (journalctl):

abr 16 09:25:30 mypc alsactl[1652]: /usr/bin/alsactl: do_nice:165sched_setparam failed: No such file or directory
If sched_setscheduler() returns 0, so it means that the call was successful.

When doing loopback between two audio card with
same sampling frequency, I noticed slow increase
of pitch_diff.
When I changed order of get_queued_playback_samples()
vs get_queued_capture_samples(), I noticed same drift
of pitch_diff but if was decreasing this time.
This seems to be caused by non-atomic consecutive
snd_pcm_delay() invocation for playback then for
capture. snd_pcm_delay() measures delay between
read/write call and actual ADC/DAC operation.
So while we get this value for playback path in
get_queued_playback_samples(), next call to
get_queued_capture_samples() will happen a little
bit later so snd_pcm_delay() may return incorrect
value.
Be interleaving get_queued_{playback,capture}_samples()
order, we divide this small error between playback
and capture paths. I do not see any issues anymore
with one-way drift of pitch_diff.
