ENGINE module additions.

Add "init" command to control ENGINE
initialization.

Call ENGINE_finish on initialized ENGINEs on exit.

Reorder shutdown in apps.c: modules should be shut
down first.

Add test private key loader to openssl ENGINE: this
just loads a private key in PEM format.

Fix print format for dh length parameter.

CONF_modules_unload() now calls CONF_modules_finish()
automatically.

Default use of section openssl_conf moved to
CONF_modules_load()

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.

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.

everywhere.

missed any.

This compiles and runs on Linux, and external applications have no
problems with it.  The definite test will be to build this on VMS.

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.

At the same time, add VMS support for Rijndael.

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.

The message to everyone is "Do not hack OpenSSL when stressed"...

EGD should be used as seeding input, and where the named socket is.

like Malloc, Realloc and especially Free conflict with already existing names
on some operating systems or other packages.  That is reason enough to change
the names of the OpenSSL memory allocation macros to something that has a
better chance of being unique, like prepending them with OPENSSL_.

This change includes all the name changes needed throughout all C files.

- Move DH parameter components inside the function.
- Automatically #include the required header file if it
  has not already been #included.

-Wmissing-prototypes -Wmissing-declarations -Wnested-externs -Winline''.

Add new program dhparam and update docs.

Remove references to 'TXT' in -inform and -outform switches.

and to lots of PEM_... functions.
