This ensures they are emitted in .data.rel.ro rather than .data.rel,
which should make a nice difference when using prelink.

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.

Instead of link_fd, more generic callback link_slaves is introduced.
This is called for linking the slave streams as the source to the
given master stream.
Some io plug-ins might want to adjust the reported delay value and not
strictly follow the current buffer usage (that's why we have two calls
after all).
Allow them to specify a delay() callback and use the previous behaviour
if they don't.

- Added protocl version check. The caller of snd_pcm_{io|ext}plug_create()
must fill version field with SND_PCM_{IO|EXT}PLUG_VERSION beforehand.
- Added poll_descriptors and poll_descriptors_count callbacks for ioplug.
