various: make filter internal function names more descriptive

Lots of filters have generic internal function names like "process".
On a stack trace, all of the different filters use this name,
which causes confusion of the actual filter being processed.

This renames these internal function names to carry the filter names.
This matches what had already been done for some filters.
