Remove redundant tests now that str is unicode.

This eliminates a few redundant test cases.

ByteArrayAsStringTest.fixtype() was converting test data to bytes, not byte-
array, therefore many of the test cases inherited in this class were not
actually being run on the bytearray type.

The tests in buffer_tests.py were redundant with methods in string_tests
.MixinStrUnicodeUserStringTest and string_tests.CommonTest. These methods are
now moved into string_tests.BaseTest, where they will also get run for bytes
and bytearray.

This change also moves test_additional_split(), test_additional_rsplit(), and
test_strip() from CommonTest to BaseTest, meaning these tests are now run for
bytes and bytearray. I plan to eliminate redundancies with existing tests in
test_bytes.py soon.

* test_contains() did not override anything
* test_expandtabs/upper/lower() in FixedStringTest were masking usable tests
  in string_tests. These tests now get run for bytearray() and bytes().
* test_expandtabs/upper/lower() in buffer_tests were only run on bytearray()
  and are redundant with string_tests

return True when finding the empty string and the indexes are completely out
of range.

Fix a regression from changeset d544873d62e9 (issue #15989).

when result of PyInt_AsLong() or PyLong_AsLong() narrowed
to int without checks.

This is a backport of changesets 13e2e44db99d and 525407d89277.

#16910: test_bytes, test_unicode, and test_userstring now work with unittest test discovery.  Patch by Zachary Ware.

Replace _s with ptr to avoid future confusion. Add also non regression tests.

Issue #14700: Fix two broken and undefined-behaviour-inducing overflow checks in old-style string formatting.  Thanks Serhiy Storchaka for report and original patch.

#14081: The sep and maxsplit parameter to str.split, bytes.split, and bytearray.split may now be passed as keyword arguments.

Also broaden the category of characters that count as lowercase/uppercase.

of bytes and bytearray objects now accept an integer between 0 and 255
as their first argument.  Patch by Petri Lehtinen.

Issue #13012: Allow 'keepends' to be passed as a keyword argument in str.splitlines, bytes.splitlines and bytearray.splitlines.

#12266: Fix str.capitalize() to correctly uppercase/lowercase titlecased and cased non-letter characters.
