Instead of keeping modified asound.h and asequencer.h, copy the files
in the kernel include/uapi/sound as is, and give some renames for
avoiding conflicts with alsa-lib's definitions.
Some structs, unions and typedefs in asound.h and asequencer.h are
once renamed in local.h before inclusion, then renamed back again.
A bonus by this action is that some local codes don't have to refer to
sndrv_xxx any longer. However, some codes like src/seq/seq.c need
explicit cast because of unavoidable conflicts of struct types.
Another significant change is that now snd_pcm_sw_params.period_event
field is removed. Instead, try to access the last reserved field
internally.

The contents of the snd_timer_query_ops structure are not going to be
changed, so we might as well declare is as constant. This change avoids
a warning if some ops structure is actually defined as const.

Add configuration options to change the default device path from the
default /dev/snd. This is useful for embedded systems that do not want
subdirectories in /dev.
Remove several memory leaks by not aborting prematurely from a
snd_xxx_close() function when some operation fails.
This can happen when a USB device was unplugged.
