[WIP] Add .clang-format to help with patch formatting

This is based on CB:38208 but with a few added items. It's just a
brain dump that has not been thoroughly tested. If it's useful and
gets polished up then it will be squashed into Vadim's version.

For now, this patch has the sources and headers modified as per the
current patchset's .clang-format to illustrate its effects. We might
choose not to modify the sources at the same time the config file is
merged.

See also CB:42556 which uses uncrustify instead of clang-format.
