respectively instead of duplicating their values.

o _POSIX_CHILD_MAX increased to 25
o _POSIX2_RE_DUP_MAX renamed _POSIX_RE_DUP_MAX
o _POSIX_SYMLINK_MAX and SYMLINK_MAX added (same as PATH_MAX)
o _POSIX_SYMLOOP_MAX and SYMLOOP_MAX added (like MAXSYMLINKS)

(like it used to be).  Fixes skey w/ sha1 as noticed by David Krause.

for the host byte order is when we copy the final digest (and that
is just an optimization).

man help jmc@

Use sizeof() in the Init functions where it makes sense.
Use weak aliases instead of wrapper functions.
Probably should have gone in before the major bump but as these are only
used internally by the sha2 functions themselves there should be no problem.

It was defined before and there is no need to for this knob...

OK otto@

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@
