Subject: [PATCH] tracing/filters: Unify the regex parsing helpers

The filter code has stolen the regex parsing function from ftrace to
get the regex support.
We have duplicated this code, so factorize it in the filter area and
make it generally available, as the filter code is the most suited to
host this feature.
