The bindings only wrap the HAL interface, rather than the entire C++ Notifier,
as I ran into issues trying to wrap the whole Notifier (all the existing
bindings only wrap HAL components, so wrapping stuff in :wpilibc is
unexplored). As such, the new edu.wpi.first.wpilibj.Notifier is just a
re-implementation of the wpilibc/.../Notifier.cpp.
The purpose of doing this bindings is to allow Java users a better option
for running tasks which require good timing (such as control loops). The
previous method used java.util.Timer to schedule a task, causing various
issues. Although this update does improve things, Java loop timing is still
substantially worse than that of C++, and, even worse, if Java decides to call
the garbage collector at the wrong time then the loop can be delayed by
multiple milliseconds and the next iteration will be shorter to account for it
(although this particular behavior could be updated).
A few notes on individual components:
-the HAL Task.hpp and Task.cpp were modified due to compilation/linkage
issues with the JNI bindings. Nothing substantive changed.
-NotifierJNI was added to the build files for gradle.
-HALUtil was modified to include a function for getting the length of a C
pointer, rather than relying on it being 32-bit.

Currently, the JNI bindings are generated by Swig and, unfortunately,
the interface available through Java is lower-level than that for C++
(ie, direct access to the ctre code through the JNI bindings, rather
than an interface on top of that), but it does work.
See eclipse plugins for some short samples.
There are a couple of short unit tests as placeholders.
Still needs some cleaning up.

When an error is reported or an assertion fails in C++, a line is now
printed with information about where the error occured, and a stack trace
is printed.
The stacktrace isn't implemented in the HAL because it's not
hardware-dependent, so StackTrace.hpp and StackTrace.cpp are gone.
The Eclipse project template is modified to include "-export-dynamic" in
the linker options, which is necessary for stack traces.
