3c3b2c75c0 Rate-limit duplicate error messages to avoid flooding console.
Fixes artf4809.

In both C++ and Java, error messages are being sent to both the console
(via stdout/stderr) and being reported via the HAL.  We don't want to
remove the stdout/stderr reporting at present because users debugging only
via netconsole (e.g. using riolog) won't see the HAL-reported errors.  Until
there's an alternative means to getting the HAL-reported errors to those
users, instead store the previous 5 error messages and don't duplicate them
more often than once per second.

Changes the error reporting from setErrorData() to sendError(), which
improves driver station error reporting.  The "location" in C++ is given as
the immediate caller (e.g. the WPILib function).  The "location" in Java is
given as the first user function in the call stack.  Note the full call stack
is provided in both instances.

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).

351e8599ac HAL: Use extern "C" in implementation files.
This turns accidental parameter mismatches between header and implementation
into compiler errors.

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.

07be45af80 HAL: Increase safety during 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).

de39877efb artf4153 Adds HAL structure memory management
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.

4514e4489a refactored HAL library
builds two libraries, Athena  and Desktop.
Simulation should use Desktop, Robots should use Athena

Also:
 - copied Driverstation and Joystick from Devices into Sim
 - Descreased dependency of pthreads in JNI.
 - removed Simulation ifdef from non simulation
 - added missing decprecated attribute for msvc
 - removed usage reporting from sim
 - removed unused pom.xml and constexpr
