Improve filter API and update filters
This patch turns upstream feedback into API modifications and code
improvements. There will be more patches implementing upstream
corrections but this one is the that will make most of the invasive
changes and make the most important improvements to the API.
Tested in a GTA02/rev06.
The goals of this patch are:
* Replace recursive calls with iteration.
* General code improvements.
* Make ts_filter_mean.c a reference for the rest of the filters.
* Make the (almost)minimum number of changes to the other filters so
that they compile and work, patches for cleaning these up will
come next.
* Filters should do what they were doing before.
Some important changes:
* Move "struct ts_filter tsf" in the private structures to force
a crash (or break things) if we forget to remove an open-coded cast.
* ts_filter.c/ts_filter.h
~ API modifications.
* s3c2410_ts.c:
~ Use the new API.
~ Cleanups.
* ts_filter_mean.c
~ Replace with a simple mean.
~ Use as a reference for the new API.
~ Move private structure from the .h to the .c.
* ts_filter_group.c
~ Update to use the new API.
* ts_filter_median.c
~ Update to use the new API.
* ts_filter_linear.c
~ Remove functions that are no longer needed.
Note:
I might leave some TODOs and FIXMEs with this patch. Most of them
will be removed shortly.
