cb71870dfa Use function name FIPS_drbg_health_check() for health check function.
Add explanatory comments to health check code.

05272d4c51 Perform health check on all reseed operations not associated with
prediction resistance requests. Although SP 800-90 is arguably unclear
on whether this is necessary adding an additional check has minimal
penalty (very few applications will make an explicit reseed request).

4420b3b17a Revise DRBG to split between internal and external flags.
One demand health check function.

Perform generation test in fips_test_suite.

Option to skip dh test if fips_test_suite.

de2132de93 Delete strength parameter from FIPS_drbg_generate. It isn't very useful
(strength can be queried using FIPS_drbg_get_strength ) and adds a
substantial extra overhead to health check (need to check every combination
of parameters).

9e56c99e1a Check we recognise DRBG type in fips_drbgvs.c initialised DRBG_CTX if we
don't set type in FIPS_drbg_new().

e0d1a2f80a Always return multiple of block length bytes from default DRBG seed
callback.

[min_len, max_len].

b8b6a13a56 Add continuous RNG test to entropy source. Entropy callbacks now need

42bd0a6b3c Update fipssyms.h to keep all symbols in FIPS,fips namespace.
Rename drbg_cprng_test to fips_drbg_cprng_test.

ded1999702 Change RNG test to block oriented instead of request oriented, add option
to test a "stuck" DRBG.

e5cadaf8db Only zeroise sensitive parts of DRBG context, so the type and flags
are undisturbed.

Allow setting of "rand" callbacks for DRBG.

011c865640 Initial switch to DRBG base PRNG in FIPS mode. Include bogus seeding for
test applications.

52b6ee8245 Reorganise DRBG API so the entropy and nonce callbacks can return a
pointer to a buffer instead of copying to a fixed length buffer. This
removes the entropy and nonce length restrictions.

dad7851485 Allow setting of get_entropy and get_nonce callbacks outside test mode.

591cbfae3c Initial, provisional, subject to wholesale change, untested, probably
not working, incomplete and unused SP800-90 DRBGs for CTR and Hash modes.

Did I say this was untested?
