scope so that passing a NULL digest is equivalent to the Pad function
(like it used to be).  Fixes skey w/ sha1 as noticed by David Krause.

The Pad function does padding like in Final but does not finish processing.
The FileChunk function creates a digest from a portion of a file.
Also made the length parameters consistent (and size_t).

previously lived in foohl.c.  The foohl.c files are now generated
via sed, though perhaps cpp could be used in the future.
Use u_int8_t instead of unsigned char for the buffers struct fooContext.
Add constants for buffer lengths and use them in function prototypes
and the man pages.
This is basically cosmetic surgery; there should be no functional changes.

o Add __BEGIN_DECLS/__END_DECLS to include files
o Safe macros
o Remove useless variable assignment in the End function of *hl.c
o Some minor KNF, needs more
