- ERESTART not supported platform: use EINTR instead
- add include/os_compat.h, well-used OS specific definition
- copied include/bswap.h from alsa-lib
- EPIPE and ESTRPIPE are different usage, but currently
EPIPE is used when ESTRPIPE is not defined.
To fix this problem, assign ESPIPE instead.

Introduce the -K,--lock-dir parameter to specify the locking
directory. If the locking is active, files card<NUM>.lock
are used to serialize the multiple initialization requests
(udev, service).
Allow the relative -O,--lock-file argument (it's default now).

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.

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

If load_configuration fails with open_failed == true, load_state will
jump to the out label without config being initialized and pass this
uninitialized config value to snd_config_delete. This commit fixes this
issue by initializing config with NULL and checking if it is non-null
before invoking snd_config_delete.

We added the check of asound.state file presence some time ago to
assure that alsactl gets called only if the state file is already
present. Since then, the situation has changed significantly:
e.g. now alsactl does initialize if the state file isn't present, and
the same alsa-restore.service is used to save the state. This means
that we should start this service no matter the state file exists at
the boot time or not. So, revert the old change again.

A race at creating a lock file in state_lock() was discovered
recently: namely, between the first open(O_RDWR) and the second
open(O_RDWR|O_CREAT|O_EXCL) calls, another alsactl invocation may
already create a lock file, then the second open() will return EEXIST,
which isn't handled properly and treated as a fatal error.
In this patch, we check EEXIST case and try again open() with O_RDWR.
This must succeed usually, and if it fails, handle finally as the
fatal error.

The state_lock() has a loop to wait for the lock file creation, and
the timeout value gets decremented twice mistakenly, which leads to a
half timeout (5 seconds) than expected 10 seconds. Fix it.
