For the previous couple of months, the PID tests have been hanging.
The reason that the tests have been hanging lies with the Notifier,
not the PID controller. Basically, a deadlock was occuring during
Notifier destruction when the notifier destructor was called while
the notifier interrupt handler was being called. Because the low-level
interrupt manager waits for the interrupt handler to finish executing before
disabling itself, the notifier destructor would not exit until the
ProcessQueue function finished. However, at the same time, the handler
was attempting to lock the queueMutex before continuing; the Notifier
destructor had locked the queueMutex while wrapping things up, meaning
that the last run of the handler would not complete until the destructor
did, resulting in a deadlock.
In order to repair this, I reduced the scope of the lock on the queueMutex
in the destructor so that it only locks when absolutely necessary. This
should work now.
This bug was likely introduced over the summer when we updated to stl
mutexes and locks, which may have messed up the original lock structure.
This likely did not affect any teams, as it can only occur if you are actively
destroying every* Notifier object present and if the destructor happens to be
called while the handler is being run.
*Note: the component of the destructor causing issues only ran if the last
Notifier object is being destroyed.

New functions were added to CanTalonSRX in the HAL, however they were
not added to the C side of the library.

All other HAL functions have status as the last parameter, only PDP did not.
This changes makes the PDP parameter order consistent with the rest of the HAL.

This is a major restructuring of the WPILib repository to simply build
procedures and remove the remnants of Maven from everything except the
eclipse plugins. Gradle files have been largely simplified or rewritten,
taking advantage of splitting up parts of the build into separate build
files for ease of reading.
The eclipse plugins are now in a separate project, as is ntcore. All
dependencies are resolved via Maven dependencies, with the
Jenkins-maintained WPILib repo. Project structures have also been
simplified: we no longer have separate subprojects inside wpilibc and
wpilibj. Where possible, these changes hav been done with git renames,
to make sure we still have full history for all repositories. Other
unrelated subprojects have also been broken out: OutlineViewer is now a
separate project.

Refactor common implementation parts of AnalogGyro into GyroBase.
This will make it possible to add digital gyros in a similar way to how
digital accelerometers were added.

If built without asserts enabled (e.g. -DNDEBUG), HALInitialize won't get
called. Instead call outside the assert and then do the assert.

These changes both simplify the Java code and improve performance across the
JNI boundary.
This also fixes the AnalogCrossConnectTest by adding delays to
setInterruptHigh() and setInterruptLow() to ensure the change in voltage has
time to propagate and extends the timeouts in AbstractInterruptTest.
Detailed changes:
Hoisted status checks to C. This avoids the need to create direct byte
buffers (expensive) and significantly simplifies the Java code. The C code
now directly generates the exception or reports the error to the DS.
The JVM pointer is now a global across the JNI, initialized by the OnLoad
function, avoiding the need for some of the class-specific initializers to
get this pointer for callbacks.
Opaque pointers (such as ports) are now passed as long values rather than
with a ByteBuffer wrapper.
Added extern "C" to source files. This allows earlier detection of JNI
definition mismatches to the Java source headers.
Changed JNI signatures to more closely match HAL signatures (in particular,
boolean is now universally used instead of byte for HAL bool, which cleans
up mapping back and forth to 1/0 from true/false).
