(Debian clang-format version 19.1.7 (3+build4)) with `--style=Google`.

Manual changes:
* clang-format disabled around macros with stringification (mostly
  assembly)
* some inline assembly strings were adjusted to avoid awkward line
  breaks
* trailing commas, `//` or suffixes (`ull`) added to help array
  formatting
* thread_utils.c: parameter comments were changed to the more common
  /*...=*/ style to improve formatting

The automatically generated code under swig/ was skipped.
