control, pcm: implement snd_ctl_abort() and snd_pcm_abort() functions
...
Upon an interrupt, it is necessary to abort the wait loops with the EINTR
error code. Introduce snd_*_abort() functions to handle this case.

Make seq, rawmidi and control operation structures static const.
...
Since they are never changed it does not make sense to have them in
the writeable .data section, just make sure to add const to the ops
member in the structure definitions so that there are no extra
warnings added.

Make local functions really local
...
Rename the local functions to snd1_* so that they won't be exported
out of alsa-lib.
Some functions are still kept because aserver requires them. Sigh.
