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.

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

The RAND_DRBG callbacks are wrappers around the EVP_RAND callbacks.
During uninstantiation, the EVP_RAND callbacks got lost while the
RAND_DRBG callbacks remained, because RAND_DRBG_uninstantiate()
calls RAND_DRBG_set(), which recreates the EVP_RAND object.
This was causing drbgtest failures.
This commit fixes the problem by adding code to RAND_DRBG_set() for
saving and restoring the EVP_RAND callbacks.

Move the three different DRBGs to the provider.
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).

Optimize the the AES-based implementation of the CTR_DRBG
construction, see 10.2.1 in [1].
Due to the optimizations, the code may deviate (more) from the
pseudocode in [1], but it is functional equivalence being decisive
for compliance:
"All DRBG mechanisms and algorithms are described in this document
in pseudocode, which is intended to explain functionality.
The pseudocode is not intended to constrain real-world
implementations." [9 in [1]].
The following optimizations are done:
- Replace multiple plain AES encryptions by a single AES-ECB
encryption of a corresponding pre-initialized buffer, where
possible.
This allows platform-specific AES-ECB support to
be used and reduces the overhead of multiple EVP calls.
- Replace the generate operation loop (which is a counter
increment followed by a plain AES encryption) by a
loop which does a plain AES encryption followed by
a counter increment. The latter loop is just a description
of AES-CTR, so we replace it by a single AES-CTR
encryption.
This allows for platform-specific AES-CTR support to be used
and reduces the overhead of multiple EVP calls.
This change, that is, going from a pre- to a post- counter
increment, requires the counter in the internal state
to be kept at "+1" (compared to the pseudocode in [1])
such that it is in the correct state, when a generate
operation is called.
That in turn also requires all other operations to be
changed from pre- to post-increment to keep functional
equivalence.

Previously, the initialization was done immediately in RAND_DRBG_set(),
which is also called in RAND_DRBG_uninstantiate().
This made it difficult for the FIPS DRBG self test to verify that the
internal state had been zeroized, because it had the side effect that
the drbg->data structure was reinitialized immediately.
To solve the problem, RAND_DRBG_set() has been split in two parts
static int rand_drbg_set(RAND_DRBG *drbg, int type, unsigned int flags);
static int rand_drbg_init_method(RAND_DRBG *drbg);
and only the first part is called from RAND_DRBG_uninstantiate().
