This adds support for two serialization formats for complex data types:
- Protobuf for complex objects with variable length internals that need forward and backward wire compatibility (lower speed, more flexible)
- Raw struct (ByteBuffer-style) for fixed-length objects (higher speed, less flexible)
Deserialization can be done either by creating a new object (for immutable objects) or overwriting the contents of an existing object (for mutable objects).
Implementing classes should provide inner classes that implement the Protobuf or Struct interface (in Java) or specialize the wpi::Protobuf or wpi::Struct struct (in C++). It is possible for classes to implement both. If the class itself does not implement serialization, it's possible for third parties/users to provide an implementation instead.
Uses the Google protobuf implementation for C++ and the QuickBuffers alternative protobuf implementation for Java.
FetchContent requires CMake 3.11 (released Mar 28, 2018).
Fixed this warning:
```
CMake Warning (dev) at /usr/share/cmake/Modules/FetchContent.cmake:1316 (message):
The DOWNLOAD_EXTRACT_TIMESTAMP option was not given and policy CMP0135 is
not set. The policy's OLD behavior will be used. When using a URL
download, the timestamps of extracted files should preferably be that of
the time of extraction, otherwise code that depends on the extracted
contents might not be rebuilt if the URL changes. The OLD behavior
preserves the timestamps from the archive instead, but this is usually not
what you want. Update your project to the NEW behavior or specify the
DOWNLOAD_EXTRACT_TIMESTAMP option with a value of true to avoid this
robustness issue.

This upgrade uncovered two issues:
ntcore wasn't forcing C++17, which caused a linker error with googletest
Matcher symbols:
```
undefined reference to `testing::Matcher<std::basic_string_view<char, std::char_traits<char> > >::Matcher(std::basic_string_view<char, std::char_traits<char> >)'
```
test_span.cpp wasn't including <algorithm> to use std::sort() and
std::is_sorted().
The CMake enable/disable flags as currently structured are a confusing mix of
WITH, WITHOUT, and USE with odd defaults. This changes the flags to consistently
use WITH and default the build options to everything enabled.
- Build both debug and release binaries
- Append "d" to debug libraries in the style of opencv
- Split shared and static classifiers
- Add raspbian support
