Added supercopnew implementations. (These are going into SUPERCOP.)
Renamed some intentionally buggy implementations to say bug in the name.
Extended unsafe-randomtest to also note the differing outputs.
Added tracking of signed vs. unsigned through data storage and prototypes.

Important workaround for angr issue:
Set claripy.Solver timeout of 4294967295 milliseconds.
The issue is that angr's satisfiable
treats z3.unknown as False
(along with treating z3.unsat as False
and treating z3.sat as True),
triggering equals in cases that Z3 has not verified.
By default Z3 will return z3.unknown after a timeout of 300000 milliseconds.
Disable most of the claripy simplifiers to speed up unrolling.
If random tests fail, skip SMT solving by default; controlled by internal satvalidation1 option.
Introduce internal maxsplit to limit number of universes for unrolling;
reaching the limit will trigger unrollerror.
Current limit is 100.
More serious, but still preliminary, support for simulation as double-check on unrolling.
Preliminary Rust support.
Simplest example is int32_sort2/rust.
Add sha256_200bytes and sha512_300bytes examples,
including sha512_300bytes/rust_sha2_097
to see the tests automatically catching the recent SHA-512 AVX2 bugs in version 0.9.7 of the Rust sha2 crate.
Beware that on some machines the sha256 example will trigger angr decoding failures for SHA instructions.
Add int32_sort2/compilebug and int32_sort2/linkbug examples
as tests of failure cases.
Move some slow examples out of the way for now:
core_{weight,wforce}* and decode_*{1531,4591}.
Support divisions.
Add divmod14 and divsigned examples.
Add warning-mul and warning-div.

If assertions are triggered in evaluation double-check,
generate warning-valuesfailed and continue into Z3 rather than stopping.
Add various src/*/README reflecting further successes after the angr updates in
https://github.com/angr/angr/pull/2887.
