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.

eliminate some of the -Wcast-qual warnings (debug-ben-strict target)

New function BN_pseudo_rand().
Use BN_prime_checks_size(BN_num_bits(w)) rounds of Miller-Rabin when
generating DSA primes (why not use BN_is_prime()?)

"Clean-up" stands for the fact that it's using common message digest
template ../md32_common.h and sha[1_]dgst.c are reduced down to
'#define SHA_[01]' and then '#include "sha_locl.h"'. It stands "(LP64)"
there because it's 64 bit platforms which benefit most from the tune-up.
The updated code exhibits 40% performance improvement on IRIX64
(sounds too good, huh? I probably should double check if it's not
some cache trashing that was holding it back before), 28% - on
Alpha Linux and 12% - Solaris 7/64.

so that warnings about unused variables (for certain
-D... constellations) are avoided; this corresponds to the earlier
change for SHA1.

1. The already released version was 0.9.1c and not 0.9.1b

2. The next release should be 0.9.2 and not 0.9.1d, because
   first the changes are already too large, second we should avoid any more
   0.9.1x confusions and third, the Apache version semantics of
   VERSION.REVISION.PATCHLEVEL for the version string is reasonable (and here
   .2 is already just a patchlevel and not major change).
