Format: apply clang rules

Restore SpacesBeforeTrailingComments to 2 to match current style

Then run clang-format -i **/**.{c,h,cc,cpp,hpp}
Then fix a bunch of typo (reported by gerrit)
Then fix unnecessary multiline string
Then fix whitespace for disabled clang format (reported by cpplint)

This is no-op
