P0 bug fix

I got tired of waiting for it to run, so I added some of the "worker" queue code that I wrote for the assets-for-api-docs generator.

I also tried out putting all the files in one call to clang-tidy with the -p argument, but that was still a lot slower because it runs them all on one core. This runs separate jobs for each file, simultaneously, and then reports the results at the end (associated with each file, of course).

This fixes all of the lint errors in lib/ui, except for a few (three, I think) where it would have changed the API, converting non-const references to pointers. For those, I just did NOLINT on the particular line instead of ignoring the whole file.

This reverts commit 06fef5e3.

* add information collection for safari bots

* remove unused parts. add cast to fix analyze errors

* add more information. address reviwer comments

* address reviewr comments

* typo fix

This does lint fixes for the fml and tools subdirs.

Rolls ANGLE forward to the latest version, picking up fixes for missing-newline-at-eof warnings.
