Convert Query to do virtually all compile state computation in the _compile_context() phase, and organize it all such that a plain select() construct may also be used as the source of information in order to generate ORM query state. This makes it such that Query is not needed except for its additional methods like from_self() which are all to be deprecated. The construction of ORM state will occur beyond the caching boundary when the new execution model is integrated. future select() gains a working join() and filter_by() method. as we continue to rebase and merge each commit in the steps, callcounts continue to bump around. will have to look at the final result when it's all in.

A large change throughout the library has ensured that all objects, parameters, and behaviors which have been noted as deprecated or legacy now emit ``DeprecationWarning`` warnings when invoked. As the Python 3 interpreter now defaults to displaying deprecation warnings, as well as that modern test suites based on tools like tox and pytest tend to display deprecation warnings, this change should make it easier to note what API features are obsolete. See the notes added to the changelog and migration notes for further details. Fixes: #4393 Change-Id: If0ea11a1fc24f9a8029352eeadfc49a7a54c0a1b
Applied on top of a pure run of black -l 79 in I7eda77fed3d8e73df84b3651fd6cfcfe858d4dc9, this set of changes resolves all remaining flake8 conditions for those codes we have enabled in setup.cfg. Included are resolutions for all remaining flake8 issues including shadowed builtins, long lines, import order, unused imports, duplicate imports, and docstring issues.

This is a straight reformat run using black as is, with no edits applied at all. The black run will format code consistently, however in some cases that are prevalent in SQLAlchemy code it produces too-long lines. The too-long lines will be resolved in the following commit that will resolve all remaining flake8 issues including shadowed builtins, long lines, import order, unused imports, duplicate imports, and docstring issues.

tested using pycodestyle version 2.2.0 Fixes: #3885 Change-Id: I5df43adc3aefe318f9eeab72a078247a548ec566 Pull-request: https://github.com/zzzeek/sqlalchemy/pull/343
- remove informix, maxdb, access symbols from tests etc.
- went through examples/ and cleaned out excess list() calls
become an externally usable package but still remains within the main sqlalchemy parent package. in this system, we use kind of an ugly hack to get the noseplugin imported outside of the "sqlalchemy" package, while still making it available within sqlalchemy for usage by third party libraries.
