  Suppress unsafe buffers on a file-by-file basis in src/ [1 of N]
  
  In this CL, we suppress many files but stop short of actually
  enabling the warning by not removing the line from the
  unsafe_buffers_paths.txt file. That will happen in a follow-on
  CL, along with resolving any stragglers missed here.
  
  This is mostly a manual change so as to familiarize myself with
  the kinds of issues faced by the Angle codebase when applying buffer
  safety warnings.
  
  -- Re-generate affected hashes.
  -- Clang-format applied to all changed files.
  -- Add a few missing .reserve() calls to vectors as noticed.
  -- Fix some mismatches between file names and header comments.
  -- Be more consistent with header comment format (blank lines and
     trailing //-only lines when a filename comment adjoins license
     boilerplate).
