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.
