Previously RAND_get_rand_method was returning a non-const pointer, but it
should be const. As with all other such cases, METHOD pointers are stored and
returned as "const". The only methods one should be able to alter are methods
"local" to the relevant code, in which case a non-const handle to the methods
should already exist.

This change has been forced by the constifying of the ENGINE code (before
which RAND_METHOD was the only method pointer in an ENGINE structure that was
not constant).

New cofiguration for Unixwre and SCO,with slightly better granularity.  Contributed by Tim Rice <tim@multitalents.net>

errors can be tolerated, hide the error from 'make'.
This gives shorter output both if ranlib fails and if
it works.

Note that all *_it variables are suddenly non-existant according to

This means that all Makefiles will have $(TOP) as one of the include

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.

Unify access to EGD-socket for all RAND_egd_*() methods.

Still needs to implement a proper OCSP certificate

Fix warning in RAND_egd().

Queried locations are: /etc/entropy, /var/run/egd-pool

Separate Windows and Unixly code, and start on a VMS variant that
currently just returns 0.

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

At the same time, add VMS support for Rijndael.

acceptable, since all that happens if it fails is a library with
an index, which makes linking slower, but still working correctly.
