65ff6fdafb pcm: Implement timestamp type handling in all plugins
Now all PCM plugins do support the proper timestamp type or pass it
over slaves.  The internal monotonic flag is dropped and replaced with
tstamp_type in all places.

80a43f23db pcm: Fix forward/rewind support in iec958 plugin
When forwarding or rewinding, the frame counter was not updated. This
could result in corrupted channel status words or misplaced Z-type
preamble.

3c4a22ea49 Implement the channel mapping API
Added new channel-mapping API functions.
Not all plugins are covered, especially the route, multi and external
plugins don't work yet.

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.

Fixed the infinite parse (and eventually segfault) of recursive definitions.
Also fixed the parse of a string slave PCM of direct plugins.

6b85e23fa3 Fix generation of IEC958 subframes
From: Nicolas Boullis <nboullis@debian.org>

While working on an ALSA driver for the audio part of em8300-based MPEG
decoder boards (Sigma Designs' Hollywood+ boards and Creative Labs' DXR3
boards), I think I discovered a bug in the code that generates IEC958
subframes from linear samples (iec958 plugin): M and W preambles are
swapped, and B preambles should only be used on even subframes. The
attached patch fixes this issue.

73aa2549d9 Add preamble value configuration for iec958 plugin
The preamble values can be defined in iec958 plugin configuration.
As default, Z/Y/X=8/4/2 is used.  CMI8338 has different values,
so override in its configuration.
