Rather than making include/openssl/foo.h a symlink to
crypto/foo/foo.h, this change moves the file to include/openssl/foo.h
once and for all.

Likewise, move crypto/foo/footest.c to test/footest.c, instead of

OPENSSL_NO_SSL_INTERN all ssl related structures are opaque
and internals cannot be directly accessed. Many applications
will need some modification to support this and most likely some
additional functions added to OpenSSL.

The advantage of this option is that any application supporting
it will still be binary compatible if SSL structures change.

Important SSL 2.0 bugfixes (bugs found while implementing msg_callback).

In ssl/s2_pkt.c, verify that the purported number of padding bytes is in
the legal range.

sure they are available in opensslconf.h, by giving them names starting
with "OPENSSL_" to avoid conflicts with other packages and by making
sure e_os2.h will cover all platform-specific cases together with
opensslconf.h.

I've checked fairly well that nothing breaks with this (apart from
external software that will adapt if they have used something like
NO_KRB5), but I can't guarantee it completely, so a review of this
change would be a good thing.

Slight cleanup in ssl/
