MAJOR: acl: add option -m to change the pattern matching method

ACL expressions now support "-m" in addition to "-i" and "-f". This new
option is followed by the name of the pattern matching method to be used
on the extracted pattern. This makes it possible to reuse existing sample
fetch methods with other matching methods (eg: regex). A "found" matching
method ignores any pattern and only verifies that the required sample was
found (useful for cookies).
