b1c3e69fb5 Change randombytes/1 so it always executes on a DS 
Investigation shows erratic behaviour of the CSPRNG. It may block at times
because it needs to go to the kernel and obtain more random information in
the system. Once this happens, you are blocked for quite a long time, but
we don't generally know when this happens. So just execute these directly
on the dirty scheduler.

2cad66ac2a Handle the ED25519 to Curve25519 conversion routines. 
Make sure these either execute on the Dirty Scheduler or execute with bumping
reductions.

a135bce9d3 Simplify the code base, first round: 
* Introduce enacl:verify/0 to verify the integrity of the library.
* Always run keypair functions on the dirty schedulers.
* Do not call NIFs when creating zerobytes. Avoid constructing new binary data, but reuse a constant.
* The box/box_open and box_seal/box_seal_open API is so expensive to call there is little overhead in
  running it on the DS always.

f444d1e4ac Fix box_seal/2 and box_seal_open/3. 
* Call the functions `box_seal` and `box_seal_open` to match the libsodium names in module `enacl`.
* Fix a bug in the C NIF: We should fail if the input is `<` SEALBYTES but not on `<=` SEALBYTES. The latter made it impossible to encode empty messages.
* Add variants which run directly on the interpreter scheduler for small messages.

Also:

* Provide full EQC functions for the testing purposes. This generated around 13000 random test cases in a 5 minute run, all passing.# Please enter the commit message for your changes. Lines starting

92109eb354 Improve and verify sign_*_detached functions. 
Provide non-dirty-scheduler variants for small strings, accurately bump
reductions for these strings.

While here, provide EQC test cases for the two functions.

238907e2a7 Fix bug in box_open_afternm + Improve readability of C code. 
If we write

	EXP != 0

and EXP is a very large term, it is hard to see what it gets checked against, so we rewrite it as

	0 != EXP

so we instanly see what we check against. While here, teset against 0 != crypto_box_afternm(…)
