The old headers were moved into folders because doing so avoids polluting
the system include directories.
Folder names were also normalized to lowercase.
* Fix bugs in PacGoat Java example that prevent it from working.
We have conflicting ports in use, each of which causes a crash
at startup. These changes fix those issues.
* Change to avoid a crash in Visual C++ when running simulated code.
Without this change, we would get a crash in SendableRobotBase when
constructing a Twine from the 'kOptions' constant string;
we'd get an unable to access memory exception.
Also switch eventName and gameSpecificData to fixed 64-byte arrays to avoid mallocs and
extra NetComm calls. This behavior matches 2018 LabView.
The DS caching is kept in Java to avoid JNI and/or massive amounts of allocations.
This does not increase latency because Java still only hits NetComm once.
Moving the DS caching benefits all languages other than Java, because it avoids the need
for individual implementations. If caching is ever added to NetComm, it will then only be
necessary to remove it from the HAL and Java rather than all languages.
I don't have a good way to ensure this always works, so this is going to be a documentation issue.
But initializeHardwareConfiguration is now reentrant, so we can just have all tests call it.
Instead of defining NAMESPACED_WPILIB to remove the "using namespace frc"
shim in Base.h, instead require NO_NAMESPACED_WPILIB be defined to add it.
Fix up various examples to use correct namespacing.
Also change header guards to WPI header guards.
Remove StringRef::c_str() customization, replacing the handful of uses with Twine or SmallString.
TCPStream: Include errno.h and make Windows includes lowercase for consistency.

During shared library loading, a different libLLVM can be pulled in, causing
llvm symbols from dependent libraries to resolve to that library instead of
this one. This has been seen in the wild with the Mesa OpenGL implementation
in JavaFX applications (see wpilibsuite/shuffleboard#361).
This is clearly a very breaking change. For some level of backwards
compatibility, a namespace alias from llvm to wpi is performed in the "llvm"
headers. Unfortunately, forward declarations of llvm classes will still break,
but compilers seem to generate clear error messages in those cases
("namespace alias 'llvm' not allowed here, assuming 'wpi'").
This change also moves all the wpiutil headers to a single "wpi" subdirectory
from the previously split "llvm", "support", "tcpsockets", and "udpsockets".
Shim headers will be added for backwards compatibility in a later commit.
SendableChooser::InitSendable() is written such that it saves the table
being used in an instance variable. This doesn't work if the chooser is
added to both LiveWindow and SmartDashboard. Normally it is not added to
LiveWindow because the name is empty, but if setName() is called this could
still happen. Note adding the same SendableChooser to SmartDashboard with
two different names is also not currently supported, for the same reason.
The correct solution will be to remove the instance variable, but this is
too high risk to implement mid-season, so instead just remove from LiveWindow.
* Fix SmartDashboard PutData to hook setters.
Also update all PutData values in main periodic loop (same as LiveWindow).
* Improve SmartDashboard.putData() repeat call handling.
