Split recursive mutex into their own functions (was Reduce performance hit of recursive mutex) (#495)

Browse Source 
mutex_t and mutex_ are reverted to non recursive versions (pre SDK1.2.0) and new recursive_mutex_t and recursive_mutex_ functions have been added

PICO_MUTEX_ENABLE_SDK120_COMPATIBILITY flag has been added to allow old SDK1.2.0 compatibility (i.e. mutex_t can be used recursively or not) but this is slower (and is will be removed in a future version)
