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

This is safe because of the way writes are performed: for each transmission,
all outgoing messages are concatenated in memory and only a single write()
syscall is made.
These are good to have for backwards compatibility, but discouraged for new
development (default-taking functions should be used instead). The reason
is that the exceptions must be explicitly handled and may initially work but
then fail at an inopportune moment.
Mark the similar Java functions as deprecated as well for the same reason.
Update all the docs for consistency.
Mark overridden functions as such in both C++ and Java.
Make IsPersistent and GetFlags const in C++.
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 will be revisited once the NI Driverstation is needed for sim

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
read each solenoid individually.

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.
