[OPTIM] halog: check once for correct line format and reuse the pointer

Almost all filters first check the line format, which takes a lot of code
and requires parsing back and forth. By centralizing this test, we can
save about 15-20 more percent of performance for all filters.

Also, the test was wrong, it was checking that the source IP address was
starting with a digit, which is not always true with local IPv6 addresses.
Instead, we now check that the next field (accept field) starts with an
opening bracket and is followed by a digit between 0 and 3 (day of the
month). Doing this has contributed a 2% speedup because all other field
calculations were relative to a closer field.
