- most in doxygen doc that was never renamed
- some re-introduced in comments/doc/strings by me

/**
* @addtogroup rng_module Random number generator (RNG) module
*
* The Random number generator (RNG) module provides random number
* generation, see \c ctr_dbrg_random().
*
* The block-cipher counter-mode based deterministic random
* bit generator (CTR_DBRG) as specified in NIST SP800-90. It needs an external
* source of entropy. For these purposes \c mbedtls_entropy_func() can be used. This is
* an implementation based on a simple entropy accumulator design.
*
* The other number generator that is included is less strong and uses the HAVEGE
* (HArdware Volatile Entropy Gathering and Expansion) software heuristic
* which considered unsafe for primary usage, but provides additional random
* to the entropy pool if enables.
*
* \* Meaning that there seems to be no practical algorithm that can guess
* the next bit with a probability larger than 1/2 in an output sequence.
*
* This module can be used to generate random numbers.
