Uncompyle6

====================

- All Python 2.6.9 standard library files weakly verify
- Many 3.6 fixes. 84% of the first 200 standard library files weakly compile.
One more big push is needed to get the remaining to compile
- Many decompilation fixes for other Python versions
- Add more to the test framework
- And more add tests target previous existing bugs more completely
- sync recent license changes in metadata

====================

- deparse_code() and lookalikes from the various semantic actions are
now deprecated. Instead use new API code_deparse() which makes the
version optional and bundles debug options into a dictionary.
- License changed to GPL3.
- Many Python 3.6 fixes, especially around handling EXTENDED_ARGS
Due to the reduction in operand size for JUMP's there are many
more EXTENDED_ARGS instructions which can be the targets
of jumps, and messes up the peephole-like analysis that is
done for control flow since we don't have something better in place.
- Code has been reorganized to be more instruction nametuple based where it
has been more bytecode array based. There was and still is code that had
had magic numbers to advance instructions or to pick out operands.
- Bug fixes in numerous other Python versions
- Instruction display improved
- Keep global statements in fixed order (from wangym5106)

A bit more work is still needed for 3.6 especially in the area of
function calls and definitions.

=====================

- API additions:
- add fragments.op_at_code_loc() and
- fragments.deparsed_find()_
- Better 2.7 end_if and COME_FROM determination
- Fix up 3.6+ CALL_FUNCTION_EX
- Misc pydisasm fixes
- Weird comprehension bug seen via new loctraceback
- Fix Python 3.5+ CALL_FUNCTION_VAR and BUILD_LIST_UNPACK in call; with this
we can handle 3.5+ f(a, b, *c, *d, *e) now

=====================

- Add `--linemap` option to give line correspondences
between original source lines and reconstructed line sources.
It is far from perfect, but it is a start
- Add a new class of tests: tests which when decompiled check themselves
- Split off Python version semantic action customizations into its own file
- Fix 2.7 bug in `if`/`else` loop statement
- Handle 3.6+ `EXTENDED_ARG`s for `POP_JUMP_IF..` instructions
- Correct 3.6+ calls with `kwargs`
- Describe the difficulty of 3.6 in README

=====================================

- Bug fixes
- Code fragment improvements
- Code cleanups
- Expand testing

=====================

- Fix bug in 3.5+ `await` statement
- Better version to magic handling; handle 3.5.2 .. 3.5.4 versions
- Improve/correct test_pyenvlib.py status messages
- Fix some 2.7 and 2.6 parser bugs
- Fix `whilelse` parsing bugs
- Correct 2.5- decorator parsing
- grammar for decorators matches AST a little more
- better tests in setup.py for running the right version of Python
- Fix 2.6- parsing of "for .. try/else" ... with "continue" inside
