We rely on the include path to find many of these headers. It
especially doesn't make sense to use #include "foo.h" for headers
in the top-level include directory.
Previously we were using 504 and 1016 which still produces the
correct result since padding is done in 8-bit bytes. However, using
size-1 for the bitwise AND makes the intent clearer and likely would
have prevented the previous bug in SHA512Pad.

Resolves an issue where certain message sizes result in an incorrect
checksum. Specifically, when:
(n*8) mod 1024 == 896
where n is the file size in bytes.
Previously we needed to include headers required by the various
sudo*h files. Now those files are more self-sufficient and we
should only include headers needed by code in the various .c files.
