dffaa0abb9 Moves HAL cpp headers from root to HAL directory (#174)
Could not include the ctre and NetComm folders, as those would require
changing ctre dependancies. Also removes a duplicated FRCComm header
that was not needed.

776a991d61 Moves Notifier over to handles (#97)
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.

8fc55c80a9 Renames all our .hpp HAL files to .h (#44)
Adds consistency, as the HAL was .hpp however all other code was .h.

3cd1253977 artf2612: Update license in source files.
Years update, references to WIND_BASE were removed, and WPILib license was
moved to the root directory of the project.

If there was already a comment block, a year range through 2016 was created
using the first year in the comment. If there was no comment block, a block
with just the year 2016 was added.

Comments were not added to files from external sources (NI, CTRE).

e2ec34090a Keep track of FPGA time rollovers with 64-bit time.
This allows both greater than 72 minute (2^32 * 1 us) timeouts and also
gracefully handles notifiers across the FPGA time counter rollover.

5dc5ed83b3 Rewrite Java Notifier and update Interrupt JNI.
Notifier takes advantage of the multi-notifier support now in HAL.

Each Notifier is now handled by a separate thread at the JNI level, so
one notifier taking longer to process (or being breakpointed) does not
stop the other notifiers from running.  These threads are configured as
daemon threads.

In both Notifier and Interrupt JNI, the JNI thread attachment no longer
repeatedly calls AttachCurrentThread().  This improves performance but more
importantly avoids impacting the Eclipse debugger, which attempts to
track each call to AttachCurrentThread() as a separate Java thread.

Note: There is currently no way to free an interrupt handler.  Repeatedly
calling attachInterruptHandler() will result in leaking previous handlers.

03c43a46d7 HAL: Add support for multiple Notifiers.
This is a poor man's version of the multi-instance Notifier support in
the higher level languages.  It's intended primarily so that notifiers
can be created internal to the HAL.

One benefit of this change is that the current FPGA timestamp is passed
as the first parameter to the ProcessQueue function (rather than the
useless interrupt mask).

Caution for other languages wrapping the HAL: this adds a parameter to
initializeNotifier().

An atexit hook is used for safe cleanup at program termination.

6d854afb0e WPILib Reorganization
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.
