MEDIUM: acl: use the fetch syntax 'fetch(args),conv(),conv()' into the ACL keyword
If the acl keyword is a "fetch", the dedicated parsing function
"sample_parse_expr()" is used. Otherwise, the acl parsing function
"parse_acl_expr()" is extended to understand the syntax of a series
of converters placed after the "fetch" keyword.
Before this patch, each acl uses a "struct sample_fetch" and executes
it with the "<fetch>->process()" function. Now, the dedicated function
"sample_process()" is called.
These syntax are now avalaible:
acl bad req.hdr(host),lower -m str www
http-request redirect prefix /go-away if bad
acl bad hdr_beg(host),lower www
http-request redirect prefix /go-away if bad
