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 Change-Id: I3bc951a3da90d24c5589fae4d1ca2bb60225c873

/**

* The Resource class is a convenient way to track allocated resources.
|
|
* It tracks them as indicies in the range [0 .. elements - 1].
|
|
* E.g. the library uses this to track hardware channel allocation.
|
|
*
|
|
* The Resource class does not allocate the hardware channels or other
|
|
* resources; it just tracks which indices were marked in use by
|
|
* Allocate and not yet freed by Free.
