REORG: include: move pattern.h to haproxy/pattern{,-t}.h

It was moved as-is, except for extern declaration of pattern_reference.
A few C files used to include it but didn't need it anymore after having
been split apart so this was cleaned.

-/* Pattern matching function result.
- *
- * We're using a 3-state matching system to match samples against patterns in
- * ACLs :
- *   - PASS : at least one pattern already matches
- *   - MISS : some data is missing to decide if some rules may finally match.
- *   - FAIL : no mattern may ever match
- *
- * We assign values 0, 1 and 3 to FAIL, MISS and PASS respectively, so that we
- * can make use of standard arithmetic for the truth tables below :
- *
- *      x  | !x          x&y | F(0) | M(1) | P(3)     x|y | F(0) | M(1) | P(3)
- *   ------+-----       -----+------+------+-----    -----+------+------+-----
- *    F(0) | P(3)        F(0)| F(0) | F(0) | F(0)     F(0)| F(0) | M(1) | P(3)
- *    M(1) | M(1)        M(1)| F(0) | M(1) | M(1)     M(1)| M(1) | M(1) | P(3)
- *    P(3) | F(0)        P(3)| F(0) | M(1) | P(3)     P(3)| P(3) | P(3) | P(3)
- *
- *  neg(x) = (3 >> x)       and(x,y) = (x & y)           or(x,y) = (x | y)
- *
- * For efficiency, the ACL return flags are directly mapped from the pattern
- * match flags. A pattern can't return "MISS" since it's always presented an
- * existing sample. So that leaves us with only two possible values :
- *      MATCH   = 0
- *      NOMATCH = 3
