Previous changes permanently removed the commented-out old code for where
it was possible to create and use an ENGINE statically, and this code gets
rid of the ENGINE_FLAGS_MALLOCED flag that supported the distinction with
dynamically allocated ENGINEs. It also moves the area for ENGINE_FLAGS_***
values from engine_int.h to engine.h - because it should be possible to
declare ENGINEs just from declarations in exported headers.

* Constify the get/set functions, and add some that functions were missing.

* Add a new 'ENGINE_cpy()' function that will produce a new ENGINE based
  copied from an original (except for the references, ie. the new copy will
  be like an ENGINE returned from 'ENGINE_new()' - a structural reference).

* Removed the "null parameter" checking in the get/set functions - it is
  legitimate to set NULL values as a way of *changing* an ENGINE (ie.
  removing a handler that previously existed). Also, passing a NULL pointer
  for an ENGINE is obviously wrong for these functions, so don't bother
  checking for it. The result is a number of error codes and strings could
  be removed.

to ENGINE_free(). Also, remove "#if 0" code that has no useful future.

even more with PKIX recommendations according to RFC 2459.

so  errtt == NULL  should be OK)

OpenSSL-engine-0_9_6-stable, minus the ENGINE_ctrl() change - the HEAD
already had that fixed.

This was causing d2i_DSAPublicKey() to misbehave.

development line as well.

des_encrypt() and des_encrypt() defined on some systems (Solaris and
Unixware and maybe others), we rename des_encrypt() to des_encrypt1().
This should have very little impact on external software unless
someone has written a mode of DES, since that's all des_encrypt() is
meant for.

New cofiguration for Unixwre and SCO,with slightly better granularity.  Contributed by Tim Rice <tim@multitalents.net>

Overhaul the display of certificate details in
the 'ca' utility. This can now be extensively
customised in the configuration file and handles
multibyte strings and extensions properly.

This is required when extensions copying from
certificate requests is supported: the user
must be able to view the extensions before
allowing a certificate to be issued.
