Remove snd_runtime_check() macro.
This macro worsens the readability of codes.  They should be either
normal if() or removable asserts.

Also, the assert displays stack-dump, instead of only the last caller
pointer.

Export snd_pcm_format_size().  This function is used by some out-of-kernel
drivers.

Make snd_pcm_format_cpu_endian() macro for optimization.

Fix by Guillaume Chazarain <guichaz@yahoo.fr>:

Some tunables in /proc have a write() function, but as their
permission does not reflect it, it can be confusing to the user.

So here is a patch that corrects the mode of those files. Note that I
have only tested the 'xrun_debug' entry.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
