* DEPR: Change boxplot return_type kwarg
Part of https://github.com/pydata/pandas/issues/6581
Deprecation started in https://github.com/pydata/pandas/pull/7096
Changes the default value of `return_type` in DataFrame.boxplot
and DataFrame.plot.box from None to 'axes'.
* API: Change faceted boxplot return_type
Aligns behavior of `Groupby.boxplot` and DataFrame.boxplot(by=.)
to return a Series.

The system file encoding can cause a separator to be encoded as more
than one character even though it maybe provided as one character.
Multi-char separators are not supported by the C engine, so we need to
catch this case. Closes#14065.

contains that thousands value for date purposes (e.g. '.'), do not
interpret those characters as the thousands parameter.

The precise strategy to be taken here is open for
discussion. I tried to be reasonably fine-grained rather than slap a
generic decorator over everything because it's easier to go that
direction than the reverse. The `errstate()` blocks in the tests were
added *after* fixing all of the library code. Unfortunately, these are
less fine-grained than I would like because some of the tests have
many lines of the form `assert_array_equal(pandas_expression_to_test,
expected_raw_numpy_expression)` where `expected_raw_numpy_expression`
is what is triggering the warning. It was tedious to try to rewrite
all of that to wrap just `expected_raw_numpy_expression`. I think I
got everything exercised by the test suite except for parts of the
test suite that are skipped on my machine due to dependencies. We'll
see how things go in the CI. I haven't added any new tests yet.
Could do if requested.

Because #13985 has been fixed, ``SparseSeries`` comparison op now can return
``SparseSeries`` (it returns normal ``Series`` on current master).
also fixed a bug when ``SparseArray`` created from ``SparseSeries``
may not inherit ``dtype``.
