Also fix DigitalGlitchFilter usage reporting for C++ (only report on
construction rather than on each call) and add for Java.

The previous commit missed the MindsensorsSD540 value.
Remove wpilibc/Athena/include/NetworkCommunication/UsageReporting.h copy; it
was not actually used (all references except the one in DriverStation.cpp
had been commented out), and has been superseded by the one in HAL.hpp.

This is a digital gyro interfaced via SPI. Uses the HAL SPI accumulator.
Basic code function successfully tested on a ADXRS453.

Previously, the AnalogOutput simulating a potentiometer was setting
the output voltage assuming a supply votlage of 5V. Now it uses
the actual "5V" that is being output. The Java test was already
doing this correctly.

HalDesktop is not nessecary right now, and it breaks the mac build

This is useful primarily for debugging purposes (as the temporary file
written by the loader can't be easily loaded by gdb).

Also, the pressure switch test is wired correctly now,
so it should be working again in Java as well.

The constructor sets m_channel to UINT32_MAX and reports an error if the
channel index is out of range (or CheckDigitalChannel fails for some other
reason). A Get() following this would result in a crash because it wasn't
checking StatusIsFatal().
The new behavior now checks StatusIsFatal() and simply returns false.

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.

- Add an atexit hook to set global and watchdog to nullptr.
- Add checks to HAL functions for these nullptrs (also good checks if they
are called prior to HALInitialize).

Checking the status code in the macro before "context" is used avoids
significant overhead (string processing) in the common case when the code
is zero.

All the Error and assert calls were using const ::std::string & arguments.
When provided with a char*, the compiler was creating a temporary string
object to pass in. This was triggering mallocs everywhere, even in the
fast paths.

Implement GetAllSolenoids in the HAL so that SolenoidBase doesn't have to

Having the HAL take a NATIVE_MULTIWAIT_ID without any way to get that
structure from extern "C" code is a problem. This makes it so it just
takes a MULTIWAIT_ID, and then grabs the native handle inside the HAL.

In the current HAL, once the port structures were created, there was no
way to free the structures. The way the C++ libraries were written this
wasn't a problem, since it grabbed a copy of each and stored them in an
array on bootup. However java does not do this, and grabs new ports
every time an object is created. This causes memory leaks if an object
is ever disposed in java. The same thing looks to be happening in
python, and C# does it too currently, but that would change if this gets
merged.
Adds java memory management fixes
Adds memory management to AnalogInput and Analog Output C++
SolenoidPorts and Digital Ports are all hold static arrays with their
port pointers (although solenoid overwrites them if a new solenoid on
the same module is created), however analog always grabbed new pointers.
I would fix the solenoid one, but I don't know what the ideal way to do
it would be.
Silently ignores free(null) calls by checking passed parameter is non-null.

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
