[MEDIUM] acl: implement matching on header values
hdr(x), hdr_reg(x), hdr_beg(x), hdr_end(x), hdr_sub(x), hdr_dir(x),
hdr_dom(x), hdr_cnt(x) and hdr_val(x) have been implemented. They
apply to any of the possibly multiple values of header <x>.
Right now, hdr_val() is limited to integer matching, but it should
reasonably be upgraded to match long long ints.
