ddc6a5c8f5 Add RAND_priv_bytes() for private keys
Add a new global DRBG for private keys used by RAND_priv_bytes.

Add BN_priv_rand() and BN_priv_rand_range() which use RAND_priv_bytes().
Change callers to use the appropriate BN_priv... function.

75e2c87765 Switch from ossl_rand to DRBG rand
If RAND_add wraps around, XOR with existing. Add test to drbgtest that
does the wrap-around.

Re-order seeding and stop after first success.

Add RAND_poll_ex()

Use the DF and therefore lower RANDOMNESS_NEEDED.  Also, for child DRBG's,
mix in the address as the personalization bits.

Centralize the entropy callbacks, from drbg_lib to rand_lib.
(Conceptually, entropy is part of the enclosing application.)
Thanks to Dr. Matthias St Pierre for the suggestion.

Various code cleanups:
    -Make state an enum; inline RANDerr calls.
    -Add RAND_POLL_RETRIES (thanks Pauli for the idea)
    -Remove most RAND_seed calls from rest of library
    -Rename DRBG_CTX to RAND_DRBG, etc.
    -Move some code from drbg_lib to drbg_rand; drbg_lib is now only the
     implementation of NIST DRBG.
    -Remove blocklength

e195c8a256 Remove filename argument to x86 asm_init.
The assembler already knows the actual path to the generated file and,
in other perlasm architectures, is left to manage debug symbols itself.
Notably, in OpenSSL 1.1.x's new build system, which allows a separate
build directory, converting .pl to .s as the scripts currently do result
in the wrong paths.

This also avoids inconsistencies from some of the files using $0 and
some passing in the filename.

6e64c56066 Small primes are primes too.
Previously, BN_is_prime_fasttest_ex, when doing trial-division, would
check whether the candidate is a multiple of a number of small primes
and, if so, reject it. However, three is a multiple of three yet is
still a prime number.

This change accepts small primes as prime when doing trial-division.

38d1b3cc02 bn: fix occurances of negative zero
The BIGNUM behaviour is supposed to be "consistent" when going into and
out of APIs, where "consistent" means 'top' is set minimally and that
'neg' (negative) is not set if the BIGNUM is zero (which is iff 'top' is
zero, due to the previous point).

The BN_DEBUG testing (make test) caught the cases that this patch
corrects.

Note, bn_correct_top() could have been used instead, but that is intended
for where 'top' is expected to (sometimes) require adjustment after direct
word-array manipulation, and so is heavier-weight. Here, we are just
catching the negative-zero case, so we test and correct for that
explicitly, in-place.
