Subject: [PATCH 06/43] Support for MacOS

Split semaphore classes into Semaphore and NamedSemaphore
Semaphore is implemented with Grand Central Dispatch
NamedSemaphore uses the spin lock approach like in boost for sem_timedwait
sem_getvalue is not supported on MacOS and therefore was removed
Fixed bug (*gatewayaddress_len > 0) in MQTTSNSearchClient.c

 This Gateway can run as a transparent or aggrigating Gateway by specifying the gateway.conf.
