If a lock is used with a mutex that doesn't need to be unlocked again before the lock is destroyed, std::lock_guard can be more efficient than std::unique_lock due to less overhead.
This commit also removes a redundant set of curly braces in PIDController.cpp intended to constrain a lock's scope.

Several ctre headers were in source directories but were required by other
headers in include directories. This worked in gradle but not in cmake.

This both disables the CANTalon in the CANTalon class (which
should be redundant) and stops sending control signals in the
CanTalonSRX hal class.

This deals with the majority of the user-facing code
in wpilibC++Devices and a substantial portion of it in
wpilibC++. wpilibC++Sim and wpilibC++IntegrationTests
are untouched except where it is necessary to make them
work with the rest of the libraries.
There is still a lot to do in the following areas:
-The HAL (which we may not want to touch at all).
-The I2C, Serial, and SPI interfaces in wpilibC++Devices,
which I haven't gotten around to doing yet.
-Most wpilibC++Devices classes have void* pointers
for interacting with the HAL.
-InterruptableSensorBase passes a void *params for
the interrupt handler.
-I haven't converted all the const char* to std::strings.
-There are plenty of other cases of raw pointers still
existing.
-This doesn't fall directly under raw pointer stuff,
but move syntax and rvalue references could be introduced
in many places.
-I haven't touched vision code.
-The Resource classes conflict (one is in the hal, the other
in wpilibC++). Someone should figure out a more
permanent fix (eg, just renaming them), then doing
what I did (making a new namespace for one of them,
essentially the same as renaming it).
A few other things:
-I created a NullDeleter class which is marked as deprecated.
What this does is it can be passed as the deleter to a
std::shared_ptr so that when you are converting raw pointers
to shared_ptrs the shared_ptr doesn't do any deletion if
someone else owns the raw pointer. This should only be
used in making old raw pointer UIs.
-I had to alter the build.gradle so that it did not
emit errors when deprecated functions called deprecated
functions. Unfortunately, gradle doesn't appear to be
actually printing out gcc warnigns for some reason.
The best way I have found to fix this is to patch
the toolchains (https://bitbucket.org/byteit101/toolchain-builder/pull-request/5/make-gcc-not-throw-warnings-for-nested/diff)
so that a deprecated function calling a deprecated
function is fine but a non-deprecated function calling
a deprecated function will throw a warning (which we
then elevate with -Werror). I believe that clang
deals with this properly, although I have not
tried it myself.

Because we want to be able to compile/run wpilibC++Sim on
windows, we would prefer not to require a windows version
of pthread. This commit moves from pthread constructs to
standard library constructs.

The bindings only wrap the HAL interface, rather than the entire C++ Notifier,
as I ran into issues trying to wrap the whole Notifier (all the existing
bindings only wrap HAL components, so wrapping stuff in :wpilibc is
unexplored). As such, the new edu.wpi.first.wpilibj.Notifier is just a
re-implementation of the wpilibc/.../Notifier.cpp.
The purpose of doing this bindings is to allow Java users a better option
for running tasks which require good timing (such as control loops). The
previous method used java.util.Timer to schedule a task, causing various
issues. Although this update does improve things, Java loop timing is still
substantially worse than that of C++, and, even worse, if Java decides to call
the garbage collector at the wrong time then the loop can be delayed by
multiple milliseconds and the next iteration will be shorter to account for it
(although this particular behavior could be updated).
A few notes on individual components:
-the HAL Task.hpp and Task.cpp were modified due to compilation/linkage
issues with the JNI bindings. Nothing substantive changed.
-NotifierJNI was added to the build files for gradle.
-HALUtil was modified to include a function for getting the length of a C
pointer, rather than relying on it being 32-bit.

This fixes all encoder variants with the getRate and getPeriod methods.
The clock speed in the HAL was updated, as was the scaling factors for setting
the stall periods. A default of .5 seconds is now set for the max period.
Additionally, a long standing bug was fixed with Java 2x encoders.
Changed tests to take into account the increased default timeout on encoders

The param is capped in the HAL C++ class to [1ms, 95ms] so that zero and negative periods are caped to 1ms, and so that caller can't pass an absurdly large value, which causes TALON is appear disabled.

I also updated the C++ and Java code some. For C++, this meant making it
compile and adding in the framework for the closed-loop control of the
motor. For Java, I updated the JNI bindings with SWIG and created an
GetTemperature accessor function to demonstrate how to use the accessors
because swig does funny stuff with pass-by-reference functions.
