requirement for an engine utility since we now have that.

passed down to ld as GNU cc.

error.  When checking like engine_add() is, those errors are actually
good, so remove them.

environment variable, SHLIB_PATH.  This change makes that possible.

RSA_get_ext_data().

pointer to a const double pointe parameter, the pointer must point to
const data as well.

that are needed in the ASN.1 macros.  Hopefully, we can get rid of
those in an elegant way in the future.

few small constifying changes, and why not throw in a couple of extras
while I'm at it?

two functions that did expansion on in parameters (BN_mul() and
BN_sqr()).  The problem was solved by making bn_dup_expand() which is
a mix of bn_expand2() and BN_dup().

full version number and not just 0.  This should mark the shared
libraries as not backward compatible.  Of course, this should be
changed again when we can guarantee backward binary compatibility.

The randomness may not actually be very good (we don't know).

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.

fopen(NULL).

built using an abstracted state machine with a non-blocking IP wrapper
around it. README will follow in the next commit.
