* Switches HAL to fixed length signed integers, and adds our own HAL_Bool type
* Replaces HAL Floats with Doubles
Doubles are just as fast as floats with optimizations turned on, so
switches to all doubles. All made doubles for consistency.
* Prepends HAL/ to HAL include files. Also fixes some range errors
HAL Port is using a special handle, where the module and pin are bit
shifted straight into the handle. This is one of the few special cases
we have, but for the way port is used it is much cleaner and uses much
less memory. Plus it is generic and not specific to one type.
Internally, the linked list now uses shared_ptrs instead of raw
pointers. In addition, in the WPILib the notifier handle is now made
atomic. Then before the class is destructed, the handle is now set to 0.
This should help solve one of the existing race conditions. A 0 handle
is correctly handled down at the HAL level.
Split to match the new headers. Uses a namespace 'hal' for internal functions and globals.
SPIAccumulator merged back into SPI header, as it was not a good split. Analog
accumulator will move back to analog input when the analog split is done.
