artf4149: Removed references to VxWorks

Implemented setTaskPriority() and getTaskPriority() in Task HAL API

Removed all other unimplemented functions in HAL and removed spawnTask()

Replaced instances of pthread_t* with TASK typedef

Removed unused HAL error constants and removed commented-out classes and functions in wpilibj's HALLibrary

Changed Task class API to match the construction semantics of a std::thread
