The access flags are useful for the user space elements
with the custom access flags.
Introduce snd_ctl_elem_info_set_*() functions to set those flags
in the info structure.

It was wrongly defined with SNDRV_ prefix. Fix it.

These are mostly a copy-paste from the kernel headers. But since functions
snd_pcm_audio_tstamp_config make use of these they should be added to the
public API as well.

We have a requirement to "hide" some hardware drivers, because
other (main) UCM configuration will refer them.

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.

To my knowledge, no software is using the mixer element identifiers.
Rename them to be more consistent with the mixer API and add
Master element identifier and type.
