Make HTTP message parsing a little faster

Browse source 
ParseHttpMessage() now does a better job avoiding malloc() calls and
headers commonly sent by CloudFlare can now be consulted in constant
time using our hard-coded perfect hash table.  This increases /claim
performance from 321k to 337k qps which is 5% faster.
