Willy Tarreau b1dd9bf308 MEDIUM: pattern: use ebtree's longest match to index/lookup string beginning ...

Being able to map prefixes to values is already used for IPv4/IPv6
but was not yet used with strings. It can be very convenient to map
directories to server farms but large lists may be slow.

By using ebmb_insert_prefix() and ebmb_lookup_longest(), we can
insert strings with their own length as a prefix, and lookup
candidate strings and ensure that the longest matching one will
be returned, which is the longest string matching the entry.
