Run clang-format on entire project

Indentation fixed to 2 spaces per tab. Braces set to Stroustrup style.
Lines reflow at 80 characters. One-line method bodies are on the same
line as the signature. Space always after `//`. No indentation
on preprocessor macros. Includes are sorted lexicographically.
