Add a new keyword "IncludeByKey" that will be used to conditional
include configuration files based on the argument value supplied during
build time. For example:
IncludeByKey.DMIC_CH_COUNT {
"[1-4]" "include/platform/intel/dmic-generic.conf"
}
The above config will include the dmic-generic.conf file if the argument
value for DMIC_CH_COUNT is between 1 and 4.

Add a -D switch to be able to pass pre-processor definitions that will
be used to expand arguments in the input config file. This will be
useful to generate multiple topology binaries from the same input config
file with different argument values.
For example: if we had a pipeline config as follows:
Object.Pipeline {
volume-playback.1 {
dynamic_pipeline $DYNAMIC_PIPELINE
}
}
We can define the variable for DYNAMIC_PIPELINE as:
Define {
DYNAMIC_PIPELINE 0
}
And when pre-processing the conf file pass "-D DYNAMIC_PIPELINE=1" to
override the default value for dynamic_pipeline attribute in the input
conf file.

The driver may export only write-only elements. The previous
heuristics code do not handle this use case correctly.
Iterate through all elements and skip the write-only ones.

Linux 5.15 will introduce a new control element "Playback Pitch 1000000"
(commit 6fec018 ("usb: gadget: u_audio.c: Adding Playback Pitch ctl for
sync playback") which provides feedback mechanism for playback direction
of USB Audio Gadget. The control operates in the same way as the
existing control element "Capture Pitch 1000000".
This patch adds support for this feature.

Renaming capt_pitch to ctl_pitch to respect the naming style of
snd_ctl_elem_value_t fields in loopback_handle. Also making the variable
name suitable for planned support of playback pitch.

This patch adds --ucm-nodev (or -X) option to get those
messages back. The code works only with library 1.2.6+.
By default, these messages are suppressed:
alsactl[xxx]: alsa-lib parser.c:242:(error_node) UCM is not supported for this HDA model (HDA Intel PCH...)
alsactl[xxx]: alsa-lib main.c:1405:(snd_use_case_mgr_open) error: failed to import hw:0 use case configuration -6

The recent commit c867aa8a84 ("alsamixer: use background color
instead of COLOR_BLACK") changed the behavior of alsamixer to take the
system default background color instead of black. This caused
problems on the terminal setups that have bright background colors,
e.g. yellow is very hard to read.
It could be "fixed" by setting up the color configurations in
~/.config/alsamixer.rc, but this needs to change the all colors in
every element, which is pretty cumbersome. Instead, this patch
extends the config set command to allow user to specify the default
background color. A user like me can create their own
~/.config/alsamixer.rc file containing the line
set background black
and the old good black background is back again.
Note that, for achieving the above, we also had to shuffle the
function call order, to parse the config at first, then initialize
curses. This shouldn't matter for other behavior.

If snd-aloop device is on playback side, the required sync mode is
PLAYSHIFT. That means Loopback ctl elem "PCM Rate Shift 100000" of the
corresponding capture side of the Loopback pipe must be controlled (by
a reciprocal).
ASCII name of the playback rate shift ctl elem is specified with newly
added option -x/--prateshift, e.g.:
-P hw:Loopback,0 -S playshift \
-x iface=PCM,name='PCM Rate Shift 100000',device=1
