Note:

  The srcdir is used for the symlinks to generated include files :-(
  I've not found a better (easy) way to fix this.

8f5779eb3f ucm: add LibraryConfig support
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.

ae564665ec 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.
