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

"Make DSA_generate_parameters faster").

(including another problem in the s3_srvr.c state machine).

that function pointers are nicely tucker in their structure.

New -pkcs12 option to CA.pl.
Document CA.pl script.
Initialise and free up the extra DH fields
(nothing uses them yet though).

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()?)

word-based algorithm we are using?)

Clean up bn_mont.c.

this is what we now use to read $RANDFILE / $HOME/.rnd.
(Previously, after 'cat'ting lots of stuff into .rnd
only the first MB would be looked at.)

Bugfix for apps/enc.c: Continue if RAND_pseudo_bytes returns 0
(only -1 is an error).

Workaround so that "make test" continues anyway.

Tidy up CRYPTO_EX_DATA structures.

opening the output file with "wb" to truncate it except on VMS
(where the file now keeps its original length because it is opened
with "rb+" -- does VMS have ftruncate?)

Slightly clarify the RAND_... documentation.

(we're now using fopen(..., "rb+") instead of fopen(..., "wb"),
so the file is not truncated automatically).
