This reverts commit d068fb321f (#3420).
The 18.04 docker images now use GCC 8, which was the original reason for
updating. 20.04 uses a much more recent libc, so staying with 18.04
enables more Linux platforms to use the binaries.
* Add .clang-tidy configuration.
* A separate .clang-tidy is used for hal includes to suppress modernize-use-using
(as these are C headers).
* Add NOLINT where necessary for a clean run.
* Add clang-tidy job to lint-format workflow. This workflow is now only run on PRs.
To reduce runtime, clang-tidy is only run on files changed in the PR.
Two wpilibc changes; both are unlikely to break user code:
* BuiltInAccelerometer: Make SetRange() final
* Counter: Make SetMaxPeriod() final
After these cleanups, the only file that does not run cleanly is
cscore_raw_cv.h due to it not being standalone.
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.
The Gradle heap size is currently set to 1G, and that's becoming too
small for our Linux build.
Developers who want to override this without editing the project's
build.gradle can override these settings with gradle.properties in
GRADLE_USER_HOME (see
https://docs.gradle.org/current/userguide/build_environment.html for
details).
