9c1a0ce72d PCM: Introduce snd_pcm_chmap_t and snd_pcm_chmap_query_t
Instead of passing ambiguous integer array, define snd_pcm_chmap_t and
snd_pcm_chmap_query_t so that user can understand more easily which
element is for what.

8b14625cc3 Make all the PCM plugins ops structure constant.
This ensures they are emitted in .data.rel.ro rather than .data.rel,
which should make a nice difference when using prelink.

8ed98db259 Make some static tables and strings constants.
By doing this we move them from the .data section to .rodata setion,
or from .data.rel to .data.rel.ro.

The .rodata section is mapped directly from the on-disk file, which is
always a save, while .data.rel.ro is mapped directly when using
prelink, which is a save in a lot of cases.

  must fill version field with SND_PCM_{IO|EXT}PLUG_VERSION beforehand.
