load the "external" built-in engines (those that require DSO).  This
makes linking with libdl or other dso libraries non-mandatory.

Change 'openssl engine' accordingly.

Change the engine header files so some declarations (that differed at
that!) aren't duplicated, and make sure engine_int.h includes
engine.h.  That way, there should be no way of missing the needed
info.

implementation is contained in the application, and the capability
string building part should really be part of the engine library.
This is therefore an experimental hack, and will be changed in the
near future.

Make flag variables int instead of char.  This avoids getting into trouble on systems where char is unsigned by default

automatically, however some code was still referring to the original
pointer rather than the internal one (and thus to NULL instead of the
created pointer).

At the same time, add VMS support for Rijndael.

translate library names by only adding ".so" to them without
prepending them with "lib".  Add the flag DSO_FLAG_NAME_TRANSLATION_EXT_ONLY
for that purpose.

appropriate filename translation on the host system. Apart from this point,
users should also note that there's a slight change in the API functions
too. The DSO now contains its own to-be-converted filename
("dso->filename"), and at the time the DSO loads the "dso->loaded_filename"
value is set to the translated form. As such, this also provides an impicit
way of determining if the DSO is currently loaded or not. Except, perhaps,
VMS .... :-)

The various DSO_METHODs have been updated for this mechanism except VMS
which is deliberately broken for now, Richard is going to look at how to
fit it in (the source comments in there explain "the issue").

Basically, the new callback scheme allows the filename conversion to
(a) be turned off altogether through the use of the
    DSO_FLAG_NO_NAME_TRANSLATION flag,
(b) be handled in the default way using the default DSO_METHOD's converter
(c) overriden per-DSO by setting the override callback

(although maybe this static variable should be abolished totally,
it was introduced before RAND_status existed).
