MEDIUM: 51d: Enabled multi threaded operation in the 51Degrees module.

The existing threading flag in the 51Degrees API
(FIFTYONEDEGREES_NO_THREADING) has now been mapped to the HAProxy
threading flag (USE_THREAD), and the 51Degrees module code has been made
thread safe.
In Pattern, the cache is now locked with a spin lock from hathreads.h
using a new lable 'OTHER_LOCK'. The workset pool is now created with the
same size as the number of threads to avoid any time waiting on a
worket.
In Hash Trie, the global device offsets structure is only used in single
threaded operation. Multi threaded operation creates a new offsets
structure in each thread.
