  *.h - Standardize format, whitespace cleanup only

View this patch with -w and it should show no changes at all.

This reformats our manually maintained header files.

All defines are lined up.

All structs are given a standardized format.

All multiline macros are given consistent escaped newlines positions.

Where things are lined up we use P95 of the length, so very long things
do not cause massive indents, so a few long entries may not line up.
