Also introduce OPENSSL_USE_DEPRECATED. If OPENSSL_NO_DEPRECATED is
defined at config stage then OPENSSL_USE_DEPRECATED has no effect -
deprecated functions are not available.
If OPENSSL_NO_DEPRECATED is not defined at config stage then
applications must define OPENSSL_USE_DEPRECATED in order to access
deprecated functions.
Also introduce compiler warnings for gcc for applications using
deprecated functions

According to X6.90 null, object identifier, boolean, integer and enumerated
types can only have primitive encodings: return an error if any of
these are received with a constructed encoding.

Causes more problems than it fixes: even though error codes
are not part of the stable API, several users rely on the
specific error code, and the change breaks them. Conversely,
we don't have any concrete use-cases for constant-time behaviour here.

The client_version needs to be preserved for the RSA key exchange.

This change also means that renegotiation will, like TLS, repeat the old
client_version rather than advertise only the final version. (Either way,
version change on renego is not allowed.) This is necessary in TLS to work
around an SChannel bug, but it's not strictly necessary in DTLS.
