CRNGT is not a requirement for FIPS 140-3. FIPS 140-2 Section 4.9.2 required the execution of the Continuous Randomness Number Generation Test (CRNGT). However, this requirement is not present in FIPS 140-3. In addition, later stages of FIPS 140-2 this test was not mandatory in all cases either (cf. FIPS 140-2 IG 9.8). Executing this test requires maintaining state, which inevitably introduces complexity. Given CRNGT is redundant with respect to compliance and really provides zero practical value (see, again, FIPS 140-2 IG 9.8), we axe it.

* Make PRNG model slightly more readable (#1079) The way the PRNG model is written looks more complicated than what is actually needed. Attempt to re-write it. This also makes it slightly easier to amend with future potential changes. * Remove CRNGT (#1112) CRNGT is not a requirement for FIPS 140-3. FIPS 140-2 Section 4.9.2 required the execution of the Continuous Randomness Number Generation Test (CRNGT). However, this requirement is not present in FIPS 140-3. In addition, later stages of FIPS 140-2 this test was not mandatory in all cases either (cf. FIPS 140-2 IG 9.8).

Atm, the configured source is hard-coded in multiple workflows. This allows adding another source more easily. In addition, add some machinery to configure another source of build-time using the new define FIPS_ENTROPY_SOURCE_JITTER_CPU. * Implementation passive entropy (#1125) * Use passive entropy source method by default for FIPS build mode (#1188) Enables passive entropy method by default. In addition, adds a build-time config that can modify (at build-time) the entropy source method to CPU Jitter. * Kick CI bots * Kick CI bots, again
