The rand pool support allocates maximal sized buffers -- this is typically
12288 bytes in size. These pools are allocated in secure memory which is a
scarse resource. They are also allocated per DRBG of which there are up to two
per thread.
This change allocates 64 byte pools and grows them dynamically if required.
64 is chosen to be sufficiently large so that pools do not normally need to
grow.
