Fixes for Win32 build.

This is mostly a work around for the old VC++ problem
that it treats func() as func(void).

Various prototypes had been added to 'compare' function
pointers that triggered this. This could be fixed by removing
the prototype, adding function pointer casts to every call or
changing the passed function to use the expected arguments.
I mostly did the latter.

The mkdef.pl script was modified to remove the typesafe
functions which no longer exist.

Oh and some functions called OPENSSL_freeLibrary() were
changed back to FreeLibrary(), wonder how that happened :-)

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.

They have nothing to do with the particular PRNG (md_rand.c).

this is what we now use to read $RANDFILE / $HOME/.rnd.
(Previously, after 'cat'ting lots of stuff into .rnd
only the first MB would be looked at.)

Bugfix for apps/enc.c: Continue if RAND_pseudo_bytes returns 0
(only -1 is an error).

plain not working :-(

Also fix some memory leaks in the new X509_NAME code.

Fix so new app_rand code doesn't crash 'x509' and move #include so it compiles
under Win32.

applications.

questions now is the OpenSSL core team under openssl-core@openssl.org.  And
add a paragraph about the dual-license situation to make sure people recognize
that _BOTH_ the OpenSSL license _AND_ the SSLeay license apply to the OpenSSL
toolkit.
