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.

Updated emu10k1.h for newer version.
The size of emu10k1_fx8010_control_gpr_t is changed. The apps need to
issue SNDRV_EMU10K1_IOCTL_PVERSION first to switch to the new ABI.
Remove enum in structs from kernel API headers.
The enum is not always equivalent with int on some architectures.

This patch will add better support for Audigy DSP. More gpr,
instruction and tram. It will break binary compatibility for app
which use emu10k1 hwdep.
