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.

69d9ad70ab CMake Changes
This is the changes made by Patrick Plenefisch converting the native
code to use CMake and the CMake Maven Plugin, as opposed to the
native Maven plugin. This is to allow for compatibility with newer
versions of the GCC toolchain. All the cpp sources were moved from
maven style directories to cpp style directories for CMake.
