I missed earlier.

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).

Also make the open functions take a mode_t, not int.  OK deraadt@

the tree was stable. No point in code supporting a company which screws
its employees being in the OpenBSD tree.

handle a few subtle details caught by the regression tests: correct
termination, non copying if buffer length == 0, errno setting.
let all former users of __strerror go through strerror_r.
Work by Todd Miller and I. Okay millert@.

okay millert@.
- atoi was bogus.
- atoi was not reentrant.
- there's no reason to cast stuff to unsigned int.

o Make MD5Update() more readable
o Simplify padding in MD5Final()
o Do copy + byte flip in MD5Transform() instead of in the caller
The result is a faster md5 and the byte order foo is kept to a minimum.

functions can take a NULL buf pointer.  They will malloc memory as
needed in this case.

aligned so copy it in a way that a) is endian indepenent and b) does
not rely on alignment.  Problem found and solution tested by hshoexer@

Add constants for buffer lengths and use them.
Make bit count 64bit based on changes by niklas@ long ago.
Conver htole32n() to macros and unroll loops.

With help from avsm@

changes Niklas made to the md5 code long ago.  OK hshoexer@

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.

mcbride and i think this diff looks good but do not feel like doing the
250 meter walk to go test it
