Remove meat which either duplicates code found in apps/, or is only of value
for 20th century historians, and can be put in the Attic.
fix memory leaks. from Dirk Engling
Remove files which look like actual code compiled in libcrypto, but isn't.
One even says (in comments): HAS BUGS! DON'T USE
null a pointer to prevent double free. from Dirk Engling
Remove the certs directory that contains ancient files not used
by anything.

When compiling with AES_WRAP_TEST, make main() return a meaningful value
instead of garbage, and add this to the libcrypto regress. Note these tests
are incomplete, as they always use the default IV.
So it turns out that libcrypto on i386 platforms, unconditionaly compiles this
little gem called OPENSSL_indirect_call(), supposedly to be ``handy under
Win32''.

In my view, this is a free-win ROP entry point. Why try and return to libc
when you can return to libcrypto with an easy to use interface?

Better not give that much attack surface, and remove this undocumented
entry point.

unifdef -UAES_LONG for we do not intend to run on platforms where int is smaller
than 32 bits.
Rather than sprinkling magical numbers everywhere, we can use sizeof()
for the size of a fixed size array.

Make sure ret->name is NULL'ed before return when freeing.
