f89c5e150f Use new NetworkTables across WPILib (C++ and Java).
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.

A submodule is used to pull in ntcore.

f65e697107 Revert changes preventing old user code from compiling.
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.

98f2d08103 Changed const char* -> string in most of wpilibc.
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.

534ea134a4 artf4154: Get rid of raw pointers in C++.
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.

1ab3ea670d artf4107: Removed most "Init" functions from classes
They were either replaced with delegating constructors or merged into the only constructor in the class.

b1befed14f artf4107: clang-modernize was run on WPILib
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.

7eb8550bdb Major formatting changes (breaks diffs). No code changes.
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.
