The application should know, that there is no special
initialization sequence. It's counterpart for
"ucm: return error if boot_list is empty".

If bootlist is empty, that means there is no BootSequence defined
in the ucm for this sound card, let set_boot_user() return error,
then alsactl could have chance to use non-ucm ways to initialize the
sound card.

Otherwise, there will be a "Digital Output(S/PDIF)-Cmedia Audio" from
Gnome UI, but there is no this physical interface on the card.

The Dell Professional Sound Bar AE515 shows up in GNOME Settings with
a digital output that doesn't physically exist. Add it to the list
to suppress this.

Currently shared memory pointer is initialized to 0 and set to -1
in some, but not in all error paths.
In cleanup path of open the shm pointer is only compared to be non-NULL
before dereferencing it which leads to SEGFAULT in case it was set to -1.
This patch initializes pointer to -1 to have a unique identification
for invalid pointer and also checks for pointer being not -1 on
access in cleanup path.

This commit allows to define private alsa-lib's configuration. When
the configuration is present, the device values ("PlaybackCTL",
"CaptureCTL", "PlaybackMixer", "CaptureMixer", "CapturePCM")
are prefixed with '_ucmHEXA.' string where HEXA is replaced by the
unique hexadecimal number identifying the opened ucm manager handle.
Syntax 4
LibraryConfig.a_label.SubstiConfig {
# substituted library configuration like:
usr_share_dir "${ConfLibDir}"
}
LibraryConfig.b_label.Config {
# non-substituted library configuration like:
usr_share_dir "/usr/share/alsa"
}
The File counterparts:
LibraryConfig.c_label.SubstiFile "/some/path"
LibraryConfig.d_label.File "/some/path"
Note that for files the contents is substituted on the request,
but the file name is always substituted (useful for ${ConfDir} etc.).
The private configuration is not saved or preserved. It's life time
belongs to the opened ucm manager handle.

It may be handy to put extra configurations or symlinks to
the global runtime directory. The configurations may be
created at boot / hotplug event by udev or other scripts.

- add asserts to check if the unsigned integers are in the valid range
- replace tuple with set in the id description
- add const prefix for id1

The previous fix for memory leaks introduced a few regression.
The major one is the assert hit in the error path reaching with NULL
or uninitialized sub object. Also, in other code paths, it's possible
that an already released sub object gets freed again.
Fix those bugs by initializing the sub object properly and add a NULL
check before calling snd_config_delete().
