95eb312fad rawmidi: Add rawmidi framing API
Optionally, incoming rawmidi bytes can be put inside a frame of type
snd_rawmidi_framing_tstamp_t.
The main current benefit is that can enable in-kernel timestamping of
incoming bytes, and that timestamp is likely to be more precise than
what userspace can offer.

Tstamp type framing requires a kernel >= 5.14 and a buffer size that
is a multiple of sizeof(snd_rawmidi_framing_tstamp_t). It is only
available on input streams.

5bbe8b2fb9 uapi: Sync with 5.6 kernel ABI
This is a sync with 5.6-rc1 kernel headers.  The copy is performed
from the sanitized headers installed via make headers_install.

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.
