(before SSLeay, maybe?), it's better to have that macro protect
the compatibility header des_old.h. In the new des.h, let's use
a slightly different protecting macro.
The rationale is that there are application that might include (via
other header files, perhaps) both an old libdes des.h and OpenSSL's
des.h. Whichever comes first would overshadow the other because of
the clash in protecting macro. This fix solves that problem.

being built with it defined - it is not a symbol to affect how openssl
itself builds, but to alter the way openssl headers can be used from an API
point of view. The "deprecated" function wrappers will always remain inside
OpenSSL at least as long as they're still being used internally. :-)
The exception is dsaparam which has been updated to the BN_GENCB-based
functions to test the new functionality. If GENCB_TEST is defined, dsaparam
will support a "-timebomb <n>" switch to cancel parameter-generation if it
gets as far as 'n' seconds without completion.
key-generation and prime-checking functions. Rather than explicitly passing
callback functions and caller-defined context data for the callbacks, a new
structure BN_GENCB is defined that encapsulates this; a pointer to the
structure is passed to all such functions instead.
This wrapper structure allows the encapsulation of "old" and "new" style
callbacks - "new" callbacks return a boolean result on the understanding
that returning FALSE should terminate keygen/primality processing. The
BN_GENCB abstraction will allow future callback modifications without
needing to break binary compatibility nor change the API function
prototypes. The new API functions have been given names ending in "_ex" and
the old functions are implemented as wrappers to the new ones. The
OPENSSL_NO_DEPRECATED symbol has been introduced so that, if defined,
declaration of the older functions will be skipped. NB: Some
openssl-internal code will stick with the older callbacks for now, so
appropriate "#undef" logic will be put in place - this is in case the user
is *building* openssl (rather than *including* its headers) with this
symbol defined.
There is another change in the new _ex functions; the key-generation
functions do not return key structures but operate on structures passed by
the caller, the return value is a boolean. This will allow for a smoother
transition to having key-generation as "virtual function" in the various
***_METHOD tables.
