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.

Also make sure table listeners stop listening in their destructors. This
might be better handled by moving the table itself into ITableListener and
providing cleanup functionality there.

I'm not 100% sure whether we want these, but they are a quick
find and replace to do.
Basically, there are two primary things that we have done
this summer that break existing user code:
-Changing GetInstance() calls to return references instead
of pointers. This forces users to change from doing something
like LiveWindow::GetInstance()->AddSensor() to LiveWindow::GetInstance().AddSensor().
-Making PIDGet() and related calls const, forcing users to change
the function signatures wherever they override them.
The GetInstance() calls don't really matter to me either way,
especially since there are no real ownership issues going on there,
unlike the rest of the smart pointer-related changes.
For the const stuff, it is certainly more correct to mandate that
user PIDGet() functions be const and the such, but at the same time,
I'm not sure that there is any strong need for it, and the errors
generated are not the most helpful. While this wouldn't necessarily
be an issue for more experienced teams or completely new teams (who
don't have any old code to be reusing), it may cause issues for more
average teams who aren't familiar with the intricacies of C++ anything.

I ran the benchmark in a tmpfs with an Intel Core i5-2430M. I ran it three times for each combination of build invokation and source tree.
First, I tested "make". For master (eb7d55f), I measured an average of 42.751s with a standard deviation of 0.372s. For this commit, I measured an average of 33.394s with a standard deviation of 0.140s. There was a 9.356s, or 22%, improvement with a total error of 1.3%.
Second, I tested "make -j4". For master (eb7d55f), I measured an average of 21.723s with a standard deviation of 0.158s. For this commit, I measured an average of 16.823s with a standard deviation of 0.340s. There was a 4.900s, or 23%, improvement with a total error of 2.7%.
Change-Id: Idb3adce62ed8ef449360c6583896b6da3565cf58
Also added a GetAvgError method to the PIDController
which averages the past n error values for use with
noisy sensor values (namely, for the velocity stuff).

CANTalon declared a std::unique_ptr<CanTalonSRX> with CanTalonSRX as an incomplete type. This causes a compilation error in code using CANTalons. The CANTalonTest didn't catch this because it included ctre/CanTalonSRX.h as well as CANTalon.h. Normal user code doesn't do that.
I reviewed uses of std::unique_ptr elsewhere and determined that PIDCommand may suffer from the same problem. There is no test for PIDCommand to prove otherwise.

The HAL will remain untouched in order to maintain C-style
compatibility. A few places in wpilibc were left as
C-style strings, especially if special formatting (eg,
elaborate uses of snprintf or sscanf) was being used.
In general, const char* was changed to std::string.
character buffers used for formatting were either
untouched, changed to std::stringstream, or changed
to std::string, depending on what was done with
the buffer.

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.

Loops were converted to their range-based equivalents, variable types were replaced with auto where the type was already specified on the same line, the override keyword was added, and instances of NULL and assignments of 0 to pointers were replaced with nullptr.

The changes made in this commit do not affect any actual code,
they are purely aesthetic. I ran clang-format with google style
over all .h/.cpp files in wpilibc that weren't in wpilibC++Sim
or gtest, and the eclipse formatter over all of the Java files
using the Google eclipse formatting configuration.

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.
Change-Id: If51bf61d0a9bc65a8d497f8d91a5be8d6ff4fdcc
Currently, the JNI bindings are generated by Swig and, unfortunately,
the interface available through Java is lower-level than that for C++
(ie, direct access to the ctre code through the JNI bindings, rather
than an interface on top of that), but it does work.
See eclipse plugins for some short samples.
There are a couple of short unit tests as placeholders.
Still needs some cleaning up.

Fleshed out CANTalon interface; it currently works just to write a

When interrupts are cancelled on any interruptable class, the resource is now
freed. Previously, the resource was only freed if the object is destructed
before CancelInterrupts() is called, so it was impossible to create and
destruct more than 8 interrupts.
The interrupts resource object is now in InterruptableSensorBase instead of
SensorBase.
A synchronous interrupt integration test was added.
