Tom Augspurger da7d4734e3 DEPR: Change boxplot return_type kwarg (#12216)
* DEPR: Change boxplot return_type kwarg

Part of
Deprecation started in

Changes the default value of `return_type` in DataFrame.boxplot
and from None to 'axes'.

* API: Change faceted boxplot return_type

Aligns behavior of `Groupby.boxplot` and DataFrame.boxplot(by=.)
to return a Series.

gfyoung 5db52f0d30 API: Warn or raise for > 1 char encoded sep
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.

Robert Kern ce61b3f1c8 ENH: Fine-grained errstate handling
closes #13109
closes #13135

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.
