Pauli bc347a35d0 fips selftest: avoid relying on a real RNG for self tests
Rather than instantiate the private and primary DRBGs during the
selftest, instead use a test RNG.  This leaves the DRBG setup
pristine and permits later replacement of the seed source despite
the very early running power up self tests.

Matt Caswell f5a50c2a07 Enable locking on the primary DRBG when we create it
The primary DRBG may be shared across multiple threads and therefore
we must use locking to access it. Previously we were enabling that locking
lazily when we attempted to obtain one of the child DRBGs. Part of the
process of enabling the lock, is to create the lock. But if we create the
lock lazily then it is too late - we may race with other threads where each
thread is independently attempting to enable the locking. This results
in multiple locks being created - only one of which "sticks" and the rest
are leaked.

Instead we enable locking on the primary when we first create it. This is
already locked and therefore we cannot race.

Pauli 7d615e2178 rand_drbg: remove RAND_DRBG.
The RAND_DRBG API did not fit well into the new provider concept as
implemented by EVP_RAND and EVP_RAND_CTX. The main reason is that the
RAND_DRBG API is a mixture of 'front end' and 'back end' API calls
and some of its API calls are rather low-level. This holds in particular
for the callback mechanism (RAND_DRBG_set_callbacks()) and the RAND_DRBG
type changing mechanism (RAND_DRBG_set()).

Adding a compatibility layer to continue supporting the RAND_DRBG API as
a legacy API for a regular deprecation period turned out to come at the
price of complicating the new provider API unnecessarily. Since the
RAND_DRBG API exists only since version 1.1.1, it was decided by the OMC
to drop it entirely.

Other related changes:

Use RNG instead of DRBG in EVP_RAND documentation.  The documentation was
using DRBG in places where it should have been RNG or CSRNG.

Move the RAND_DRBG(7) documentation to EVP_RAND(7).

As part of the move, the DRBG specific data was pulled out of a common
structure and into their own structures.  Only these smaller structures are
securely allocated.  This saves quite a bit of secure memory:

    +-------------------------------+
    | DRBG         | Bytes | Secure |
    +--------------+-------+--------+
    | HASH         |  376  |   512  |
    | HMAC         |  168  |   256  |
    | CTR          |  176  |   256  |
    | Common (new) |  320  |     0  |
    | Common (old) |  592  |  1024  |
    +--------------+-------+--------+

Bytes is the structure size on the X86/64.
Secure is the number of bytes of secure memory used (power of two allocator).
