Reformat and sort all includes with clang-format

This makes it easier to see which headers includes what.

The changes were done by running

    git grep -l '#\s*include'  \
        | grep -E '.(cc|h)$' \
        | xargs sed -i -E 's/(^\s*)#(\s*)include/\1#\2 include/'

To modify all include lines by adding a space, and then running
./git-clang-format.sh.
