Copied from the kernel uapi header for control API.
A few new ioctls have been added for the support of UMP next device
and inquiries of UMP Endpoint and Block info.

The application may not require to touch the playback
sample stream for the drain operation at all. In this case,
the application is responsible to setup a silencing mechanism
for the playback or another graceful stop (like using the
rewind operation).

Handle the driver informing us that it is not necessary to set up
silencing upon playback draining. This will be the case for drivers
which are guaranteed to not read any samples beyond the application
pointer.

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.

This is a sync with 5.6-rc1 kernel headers. The copy is performed
from the sanitized headers installed via make headers_install.

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.
