Whitespace changes by clang-format.

These files are the ones with the least number of changes when running
clang-format over them and only the less controversial changes are
included, with a preference for having stay the same where things are
likely to be more controversial.
The issue with the larger files being that they take time for me to review so I can remove controversial things in favor of the common things we can agree on, like no tables and no trailing spaces and such.
