I looked at skip-chars-forward before opening this bug but found it
complicate things by introducing new rules.

In strip-string the idea is to have a default covering 90% of the use
cases:

(strip-string s)        ; strip both
(strip-string s nil "") ; strip leading
(strip-string s "")     ; strip trailing

Refer users to regexp as in (info "(elisp)Regexp Special") for the
remaining 10% use cases.
