- Twine, StringRef, Format, and NativeFormatting have been removed
- Logging now uses fmtlib style formatting
- Nearly all uses of wpi::outs/errs have been replaced with fmt::print() or
std::puts()/std::fputs() (for unformatted strings).
- A wpi/fmt/raw_ostream.h header has been added to enable
fmt::print() with wpi::raw_ostream
This makes code easier to read and more consistent between C++ and Java.
Also update clang-format settings to always add a line break (even if no braces are used).
Remove WaitForCachedData as it's no longer required.
Also properly handle caching / transition detection logic that occurs at the
WPILib level.
This also changes DriverStation::IsNewControlData() to check for WPILib-level
caching instead of wrapping the HAL function.
std::scoped_lock was introduced in C++17 and is strictly better than
std::lock_guard as it supports locking any number of mutexes safely.
It's also easier to use than std::lock for locking multiple mutexes at
once.

The static condition variable was getting destroyed before the DS thread exited,
resulting in a deadlock on program exit when the DS thread tried to notify it.
This change moves the condition variable into the DS thread to avoid the race.
The old headers were moved into folders because doing so avoids polluting
the system include directories.
Folder names were also normalized to lowercase.
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.
Also fix the return type of HAL_IsNewControlData() and HAL_MatchType's type.
Since UsageReporting is intended to be namespaced, it is hidden when this is being used in C.

Ref: #1122
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.
* Removed hal::priority_condition_variable
* Replaced uses of priority mutexes with std::mutex and std::recursive_mutex
This allowed replacing a use of std::condition_variable_any with
std::condition_variable.
* Replaced all uses of std::recursive_mutex with std::mutex equivalents
* Revert "Force OpenCV to 3.1.0 (#602)"
This reverts commit 50ed55e8e2.
