Removed delayTicks(), delayMillis(), delaySeconds(), HAL_NO_WAIT, HAL_WAIT_FOREVER,
niTimestamp32(), and niTimestamp64().
Replaced clock_gettime() and usleep() with std::chrono.
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.
Subsections are alphabetized according to lexographic ordering. Also, HAL includes were moved from headers to source files where possible. This change may cause user code which uses HAL functionality and does not include the relevant HAL header (since it may have been provided by another WPILib header) to fail to compile.
The Digital and Analog headers (and the implementations, but that will
be moved over later) are just too big and congested. This splits those
headers, and then changes the few things that needed to be changed in
WPILib to get the code working again. No function changes were made in
this commit.
As the notifierMutex is unlocked while the callback is being called in
alarmCallback(), it's possible for next to be invalidated due to a
cleanNotifier() call. Now, instead of deleting the notifier immediately,
add it to a freelist to be cleaned up at the tail end of alarmCallback.
Rename the following folders:
hal/lib/Athena -> hal/lib/athena
hal/lib/Desktop -> hal/lib/sim
hal/lib/Shared -> hal/lib/shared
wpilibc/Athena -> wpilibc/athena
wpilibc/simulation -> wpilibc/sim
Windows users may need to run gradlew clean after updating.
