CHANGES:

* CPU feature detection (AESNI, SSE3, PCLMULQ) at runtime instead of compile
  time (mirage/mirage-crypto#53 @Julow, fixed MirageOS support mirage/mirage-crypto#61, review by @hannesm)
  performance hit up to 5%
* Revise entropy collection (mirage/mirage-crypto#64 @hannesm review by @dinosaure @cfcs)
  mirage-crypto-entropy has been folded into mirage-crypto-rng.{unix,lwt,mirage}
  - the RNG is no longer fork() safe, if you use fork in your code, be sure to
    reseed the RNG in the child process
  - on Unix and Lwt, the used RNG is Fortuna, seeded by getrandom(),
    rdrand/rdseed, and whirlwind
  - Mirage_crypto_rng_lwt does entropy collection for Lwt applications
  - entropy collection is now similar to FreeBSD:
    - rdrand/rdseed is executed in a separate task (by default every second)
    - on Unix, getrandom() is executed in another separate task (by default
      every 10 seconds)
    - on every enter of the Lwt event loop, some bits of rdtsc are collected
      (rdrand/rdseed is not on each even loop enter anymore)
  - Fortuna only uses entropy pools if the given period is exhausted (defaults
    to 1s), and the pool size exceeds 64 bytes
  - The unseeded generator exception prints instructions how to seed the RNG
* 32 bit support (for ghash), requested by @TImada in mirage/mirage-crypto#60, mirage/mirage-crypto#65 @hannesm
* use Eqaf_cstruct.find_uint8 instead of Cs.ct_find_uint8 (mirage/mirage-crypto#52 @dinosaure)
* add (:standard) in C flags to allow cross-compilation mirage/mirage-crypto#47 @samoht
* Mirage_crypto.Uncommon: remove several functions (Cs.create, Option),
  requires OCaml 4.08 (mirage/mirage-crypto#49 mirage/mirage-crypto#51 @hannesm)
* remove ocplib-endian dependency, use Bytes directly (since 4.07) mirage/mirage-crypto#51 @hannesm
* bitfn.h cleanup (mirage/mirage-crypto#56 mirage/mirage-crypto#58 @hannesm)
* fix build if opam is not available (mirage/mirage-crypto#66 @hannesm)
* update test.yml GitHub actions (mirage/mirage-crypto#44 mirage/mirage-crypto#57 @imbsky)
* Travis CI for arm64 (mirage/mirage-crypto#55 @hannesm)
