v1.0.0

This is an initial project release as announced here:
http://www.flux.utah.edu/listarchives/creduce-dev/msg00475.html

Features and limitations:

1. C-Vise is a super-parallel implementation where all passes run their transform and test script
   phase in parallel; that resolves csmith-project/creduce#160; I've seen significant speed up on a 16-core Zen CPU
2. the project contains native BinaryState object which can help with fast traversal of a state space
3. Python is hopefully more popular language than Perl

Minor improvements:

• --log-level option - one can print different level of messages
• --remove-pass - one can skip a pass in pass manager (csmith-project/creduce#200, csmith-project/creduce#202)
• --list-passes - listing of existing passes (csmith-project/creduce#150)
• project contains unit tests for some passes
• LLVM 9 and 10 support (csmith-project/creduce#193, csmith-project/creduce#204)
• --clang-delta-std option - workaround for csmith-project/creduce#210
• unifdef and delta subprojects are removed from the repository
• --timing-since-start - print timestamps since the start of a reduction

Known limitations:

• configure & make build support is dropped
• FreeBSD and Windows port is not tested
• dependency on python-Pebble package
• a small issue observed in Pebble (noxdafox/pebble#58)
