still can't figure out the warnings with some of the older
changelog files.
this cherry-picks the sphinx fixes from 1.4 and additionally
fixes a small number of new issues in the 2.0 docs. However,
2.0 has many more errors to fix, primarily from the removal
of the legacy tutorials left behind a lot of labels that need
to be re-linked to the new tutorial.
Fixes: #7946

(cherry picked from commit 9b55a42345)
the session commit/close docs still feel awkward in how
one learns about this operation. hopefully another pass
over 2.0 can make things more linear.
removed a 1.4 note about autobegin that was completely inaccurate;
commit() does autobegin so it has an effect, just not usually
on the database.

this second example is not part of the doctest steps,
clarify that it's not part of code examples to be present
in execution steps. Add an extra registry +
declarative base on top
so that even if someone does run it, the Base will have
been reset and the examples will continue to work
(noting that column order in statements may change, but
probably nothing else).

This is done in 1.4 style so it can be backported to 1.4.
Will put this up as is, we can work on it. For 2.0, the
ORM mapping will be updated to mapped_column() style when
we do the full pass.

All modules in sqlalchemy.engine are strictly
typed with the exception of cursor, default, and
reflection. cursor and default pass with non-strict
typing, reflection is waiting on the multi-reflection
refactor.
Behavioral changes:
* create_connect_args() methods return a tuple of list,
dict, rather than a list of list, dict
* removed allow_chars parameter from
pyodbc connector ._get_server_version_info()
method
* the parameter list passed to do_executemany is now
a list in all cases. previously, this was being run
through dialect.execute_sequence_format, which
defaults to tuple and was only intended for individual
tuple params.
* broke up dialect.dbapi into dialect.import_dbapi
class method and dialect.dbapi module object. added
a deprecation path for legacy dialects. it's not
really feasible to type a single attr as a classmethod
vs. module type. The "type_compiler" attribute also
has this problem with greater ability to work around,
left that one for now.
* lots of constants changing to be Enum, so that we can
type them. for fixed tuple-position constants in
cursor.py / compiler.py (which are used to avoid the
speed overhead of namedtuple), using Literal[value]
which seems to work well
* some tightening up in Row regarding __getitem__, which
we can do since we are on full 2.0 style result use
* altered the set_connection_execution_options and
set_engine_execution_options event flows so that the
dictionary of options may be mutated within the event
hook, where it will then take effect as the actual
options used. Previously, changing the dict would
be silently ignored which seems counter-intuitive
and not very useful.
* A lot of DefaultDialect/DefaultExecutionContext
methods and attributes, including underscored ones, move
to interfaces. This is not fully ideal as it means
the Dialect/ExecutionContext interfaces aren't publicly
subclassable directly, but their current purpose
is more of documentation for dialect authors who should
(and certainly are) still be subclassing the DefaultXYZ
versions in all cases
Overall, Result was the most extremely difficult class
hierarchy to type here as this hierarchy passes through
largely amorphous "row" datatypes throughout, which
can in fact by all kinds of different things, like
raw DBAPI rows, or Row objects, or "scalar"/Any, but
at the same time these types have meaning so I tried still
maintaining some level of semantic markings for these,
it highlights how complex Result is now, as it's trying
to be extremely efficient and inlined while also being
very open-ended and extensible.

This PR is designed to bring more clarity within the docs by renaming object
instances that may be consfusingly similar to class, method, and attribute names.
For example, instances of the class `MetaData` are available on some objects as
`.metadata` property, and had appeared within the docs as both `meta` and
`metadata` which has confused some users in the past. By this PR, the docs now
utilize the following naming convention:
* MetaData - SQLAlchemy class
* .metadata - SQLAlchemy API attributes
* metadata_obj - developer instantiated metadata objects or references
Detailed Changes:
* standardized `meta` and `metadata` instances to `metadata_obj`. note: the docs were evenly split between 'meta' and 'metadata'.
* standardized 'cursor' to 'cursor_obj' to avoid confusion with the method.
* standardized a 'scalar_subquery = ' to 'scalar_subq' to avoid confusion with the method.
* standardized a 'cte = ' to 'cte_obj' to avoid confusion with the method

This breaks data.rst into three separate sub-sections,
as SELECT is getting very long. It then adds sections
on select() + text/literal_column as well as unions
and set operations, and also tries to improve the
ORDER BY section a bit.

existing tuple interface.

Implemented support for "table valued functions" along with additional
syntaxes supported by PostgreSQL, one of the most commonly requested
features. Table valued functions are SQL functions that return lists of
values or rows, and are prevalent in PostgreSQL in the area of JSON
functions, where the "table value" is commonly referred towards as the
"record" datatype. Table valued functions are also supported by Oracle and
SQL Server.

Replace :meth:`_orm.Query.with_labels` and
:meth:`_sql.GenerativeSelect.apply_labels` with explicit getters and
setters ``get_label_style`` and ``set_label_style`` to accommodate the
three supported label styles: ``LABEL_STYLE_DISAMBIGUATE_ONLY`` (default),
``LABEL_STYLE_TABLENAME_PLUS_COL``, and ``LABEL_STYLE_NONE``.
In addition, for Core and "future style" ORM queries,
``LABEL_STYLE_DISAMBIGUATE_ONLY`` is now the default label style. This
style differs from the existing "no labels" style in that labeling is
applied in the case of column name conflicts; with ``LABEL_STYLE_NONE``, a
duplicate column name is not accessible via name in any case.
For legacy ORM queries using :class:`_query.Query`, the table-plus-column
names labeling style applied by ``LABEL_STYLE_TABLENAME_PLUS_COL``
continues to be used so that existing test suites and logging facilities
see no change in behavior by default, however this style of labeling is no
longer required for SQLAlchemy queries to function, as result sets are
commonly matched to columns using a positional approach since SQLAlchemy
1.0.
Within test suites, all use of apply_labels() / use_labels
now uses the new methods. New tests added to
test/sql/test_deprecations.py nad test/orm/test_deprecations.py
to cover just the old apply_labels() method call. Tests
in ORM that made explicit use apply_labels()/ etc. where it isn't needed
for the ORM to work correctly use default label style now.

this should be backported to 1.3 as well to as much a degree
as possible.
Includes a new recipe to set the default schema name
on connect. this will only work on 1.4, but also requires
that we fix#5708 for it to work fully.

Multiple calls to "returning", e.g. :meth:`_sql.Insert.returning`,
may now be chained to add new columns to the RETURNING clause.

A warning is emmitted if a returning() method such as
:meth:`_sql.Insert.returning` is called multiple times, as this does not
yet support additive operation. Version 1.4 will support additive
operation for this. Additionally, any combination of the
:meth:`_sql.Insert.returning` and :meth:`_sql.Insert.return_defaults`
methods now raises an error as these methods are mutually exclusive;
previously the operation would fail silently.

Add SelectBase.exists() method as it seems strange this is
not available already. The Exists construct itself does
not provide full SELECT-building capabilities so it makes
sense this should be used more like a scalar_subquery.
Make sure stream_results is getting set up when yield_per
is used, for 2.0 style statements as well. this was
hardcoded inside of Query.yield_per() and is now moved
to take place within QueryContext.
