[PATCH 0/7] Add capture support to compress API

[Richard Fitzgerald <rf@opensource.wolfsonmicro.com>]

This chain of patches does some clearing up and add capture
support to the compressed API.

Missing is support for capture streams that don't use the
copy callback. Also I have included two patches at the end
of the chain that remove the buffer pointers and just use
the cumulative values however as our setup uses the copy
callback these are untested past build so should be taken
with caution.

Thanks,
Charles
