coding style: add "superfluous" braces

- wrap flow-controlled statements that contain blocks into blocks
  themselves
- wrap bodies of do-while()s into blocks
- use braces on 'else' symmetrically (this obviously has a cascading
  effect, so this patch touches lots of lines)
- attach braces

unavoidably, the rules are sometimes broken around #ifdef-ery.
