Fix alsa/sound/*.h for external programs
The recent update of sound/*.h to sync with the latest Linus uapi
files broke the build of alsa-tools programs. These files used to be
a modified version of Linux sound/* header files, so that they could
be built without Linux headers. The special prefix like __user and
other things were worked around there.
We may do that again, but a better approach is to fix those things in
Linux kernel uapi side, while we keep the minimal workaround in
alsa-lib such as the __u16 and co type definitions.
This patch is such an attempt, namely:
- Keep the original $LINUX/uapi/sound/*.h in include/sound/uapi
directory
- The "fixes" are applied to some uapi headers, so that they don't
contain Linux-specific prefix and use of opaque struct like
snd_ctl_elem_id
- The uapi headers are included indirectly from include/sound/*.h
- Some headers have inclusion of type_compat.h for the Linux variable
types and prefixes
- type_compat.h tries to use <linux/types.h> when __linux__ is
defined, instead of the own conflicting definitions
The last type might need a bit more adjustment depending on the
compiler, but it can be fixed locally without disturbing else.

ucm: Do not fail to parse configs on cards with an empty CardComponents lists
Since the UCM profiles for all Bay- and Cherry-Trail SST cards have been
moved over to UCM2, parsing them fails with:
ALSA lib ucm_subs.c:220:(uc_mgr_get_substituted_value) variable '${CardComponents}' is not defined in this context!
This completely breaks audio support on all Bay- and Cherry-Trail devices.
This is caused by these non-SOF ASoC using cards having an empty
CardComponents list. Which in itself is fine, but is rejected by
the ucm_subs.c code. This commit changes the ucm_subs code to accept
an empty string as a valid value for CardComponents restoring audio
functionality on these boards.

ucm: fix again the long name configuration filename lookup
The fix in commit 77119d83a1f4 assumes that both ucm1 / ucm2 directories
have the configurations for the long name in the same directory. For v2
we changed the location to card_name/card_long_name aka
driver_name/driver_long_name to make the directory layout more structured.

ucm: Only look in ucm[1] or ucm2 dir once we've found a config file in one
Unless environment variables are set, then configuration_filename()
when initially called by load_master_config() will first try to find
the requested master-config under <prefix>/alsa/ucm2 and then under
<prefix>/alsa/ucm.
Once a master-config is found this way, we should set conf_format to
match, so that subsequent lookups only look under the same directory
as where the master-config was found.
This fixes 2 problems:
1. uc_mgr_config_load() looking under <prefix>/alsa/ucm for includes for
UCM2 profiles because it is called with uc_mgr->conf_format as format
and before this commit that would stay 0 when autodetecion is used.
2. parse_verb_file() possibly loading an UCM2 verb-file for an UCM1 profile,
the chance of this happening is small as this means that even though
there is no UCM2 master-config there is an UCM2 profile dir matching
uc_mgr->conf_file_name, which would be weird.

ucm: Fix fallback to card_name (shortname) config for ucm1 profiles
uc_mgr_import_master_config() first calls load_master_config()
with the card's longname and if that fails then calls it again with the
card_name.
Before this commit configuration_filename() would force conf_format to 2
when it the access(fn, R_OK) test failed for the ucm1 longname
master-config filename.
This would cause configuration_filename() to blindly return a filename
under <prefix>/ucm2 without seeing if that is actually there and without
trying to fallback to the old profiles under <prefix>/ucm, breaking the
loading of UCM1 profiles by card_name.
This commit fixes this by modifying configuration_filename() to not set
conf_format when checking for the UCM1 config filename fails.
Instead, to make sure that any errors about opening the file still report
the new path, configuration_filename() now resets the filename to the UCM2
path if the access() check has failed for both the UCM2 and UCM1 paths,
without touching conf_format.

ucm: Fix opening of master-configs by the card's longname
Prior to commit aba2260ae7b5 ("ucm: switch to ucm2 directory and v2 format,
keep backward compatibility").
The filename build in parse_verb_file() was build like this:
<prefix>/<uc_mgr->conf_file_name>/<file>
Where uc_mgr->conf_file_name would contain either the card_name or the
card's longname depending on the detection of a longname based config in
uc_mgr_import_master_config().
While the filename used in load_master_config() was build like this:
<prefix>/<card_name>/<card_name>.conf
And uc_mgr_import_master_config() first calls load_master_config()
with the card's longname and if that succeeds it overwrites
uc_mgr->conf_file_name with the longname so that the subsequent uses
of uc_mgr->conf_file_name in parse_verb_file() correctly use the longname.
But the new configuration_filename() helper added in commit aba2260ae7b5
_always_ builds the filename like this:
<prefix>/<uc_mgr->conf_file_name>/<file><suffix>
This breaks the loading of the master-config by its longname, as when
the longname is tried uc_mgr->conf_file_name still contains the card_name.
This commit fixes this by adding a dir parameter to configuration_filename()
and restoring the old behavior by passing card_name as dir in
load_master_config().
