CTR, HASH and HMAC DRBGs in provider
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).
