_XOPEN_SOURCE_EXTENDED wasn't very smart...

to go the monolith way (does anyone do that these days?).

NOTE: a few applications are missing in this commit.  I've a few more
changes in them that I haven't tested yet.

password callbak doesn't need to check for sizes any more.

application do that.

NOTE: there's no requirement for other UI_METHODs to avoid this kind
of loop.  For example, a GUI UI_METHOD would probably check the
lengths of the answers from within instead of being constantly
redisplayed for everything that is wrong.

Implement UI controls.  Current controls are the possibility to output
the OpenSSL error stack on the same channel from within UI_process()
and to check if the same user interface can be redone without being
rebuilt (this is often more a question of philosophy than
technicalities).

errors through an arbitrary function.

success return, any negative number is a failure.  Make sure we check
the return value with that in mind.

I was wrong in conclusions about when addition starts overflowing in combaX
routines.

Fix memory leak when RAND is used: need to cleanup
RANDs ENGINE reference in ENGINE_cleanup().

well.

This probably requires reference counters and locks as well.  To be
implemented later.

commands appropriately.

Change all calls to low level digest routines in the library and
applications to use EVP. Add missing calls to HMAC_cleanup() and
don't assume HMAC_CTX can be copied using memcpy().

Note: this is almost identical to the patch submitted to openssl-dev
by Verdon Walker <VWalker@novell.com> except some redundant
EVP_add_digest_()/EVP_cleanup() calls were removed and some changes
made to avoid compiler warnings.

file part of the password prompt unless it's standard input...

More will be added...

prompting, even when done through the callback.

  with arbitrary arguments instead of just a string.
- Change the key loaders to take a UI_METHOD instead of a callback
  function pointer.  NOTE: this breaks binary compatibility with
  earlier versions of OpenSSL [engine].
- Addapt the nCipher code for these new conditions and add a card
  insertion callback.

someone having a default that is not a password will be confused.

prompting, application-defined prompts, the possibility to use
defaults (for example default passwords from somewhere else) and
interrupts/cancelations.
