Load config file in several openssl utilities.

Most utilities now load modules from the config file,
though in a few (such as version) this isn't done
because it couldn't be used for anything.

In the case of ca and req the config file used is
the same as the utility itself: that is the -config
command line option can be used to specify an
alternative file.

Add AES support in the applications that support -des and -des3.

Reduce the header dependencies on engine.h in apps/.

Provide an application-common setup function for engines and use it
everywhere.

Extend all the loading functions to take an engine pointer, a pass
string (some engines may have certificates protected by a PIN!) and
a description to put into error messages.

Extend all the loading functions to take an engine pointer, a pass
string (some engines may have certificates protected by a PIN!) and
a description to put into error messages.

Also, have our own password callback that we can send both a password
and some prompt info to. The default password callback in EVP assumes
that the passed parameter is a password, which isn't always the right
thing, and the ENGINE code (at least the nCipher one) makes other
assumptions...

Also, in spite of having the functions to load keys, some utilities
did the loading all by themselves... That's changed too.

Make all configuration macros available for application by making
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.

Initial OCSP certificate verify. Not complete,

Merge the engine branch into the main trunk. All conflicts resolved.
At the same time, add VMS support for Rijndael.

On VMS, stdout may very well lead to a file that is written to in a
record-oriented fashion. That means that every write() will write a
separate record, which will be read separately by the programs trying
to read from it. This can be very confusing.

The solution is to put a BIO filter in the way that will buffer text
until a linefeed is reached, and then write everything a line at a
time, so every record written will be an actual line, not chunks of
lines and not (usually doesn't happen, but I've seen it once) several
lines in one record. Voila, BIO_f_linebuffer() is born.

Since we're so close to release time, I'm making this VMS-only for
now, just to make sure no code is needlessly broken by this. After
the release, this BIO method will be enabled on all other platforms as
well.
