during "make errors" and thus during "make update".

Fix lots of bugs that util/ck_errf.pl can detect automatically.
Various others of these are still left to fix; that's why
"make update" will complain loudly when run now.

cause a segfault...  This was uncovered because EVP_VerifyInit() may fail
in FIPS mode if the wrong algorithm is chosen...

I've covered all the memset()s I felt safe modifying, but may have missed some.

Retain compatibility of EVP_DigestInit() and EVP_DigestFinal()
with existing code.

Modify library to use digest *_ex() functions.

currently OpenSSL itself wont compile with this set
because some old style stuff remains.

Change old functions X509_sign(), X509_verify() etc
to use new item based functions.

Replace OCSP function declarations with DECLARE macros.

The old function pointer versions will eventually go
away.

like Malloc, Realloc and especially Free conflict with already existing names
on some operating systems or other packages.  That is reason enough to change
the names of the OpenSSL memory allocation macros to something that has a
better chance of being unique, like prepending them with OPENSSL_.

This change includes all the name changes needed throughout all C files.

This will soon be complemented with MacOS specific source code files and
INSTALL.MacOS.

I (Andy) have decided to get rid of a number of #include <sys/types.h>.
I've verified it's ok (both by examining /usr/include/*.h and compiling)
on a number of Unix platforms. Unfortunately I don't have Windows box
to verify this on. I really appreciate if somebody could try to compile
it and contact me a.s.a.p. in case a problem occurs.
