- confusing line_offset parameter -> first_line parameter
- systematically test and fix new file parameter
- remove redundant Bytecode.show_info() API
- rename Bytecode.display_code() to Bytecode.dis() and have it
  return the multi-line string rather than printing it directly
- eliminated some not-so-helpful helpers from the bytecode_helper
  test support module

Also fixed a longstanding defect (worked around in the test suite)
where lines emitted by the dis module could include trailing white
space. That no longer happens, allowing the formatting tests to be
simplified to use plain string comparisons.

Py_DECREF(self) if PyThread_allocate_lock() failed instead of calling directly
type->tp_free(self), to keep the chained list of objects consistent when Python
is compiled in debug mode

fails, don't consume the row (restore it) and fail immediatly (don't call
pysqlite_step())

Issue #10197 Tweak docs for subprocess.getstatusoutput and align the documentation, the module docstring, and the function docstring.

Some third-party projects, such as matplotlib and PIL/Pillow,
depended on being able to build with Tcl and Tk frameworks in
/Library/Frameworks.  They were unable to build with the built-in
Tcl/Tk and/or execute correctly.

Move the test to PyUnicode_Compare()

pointer) for any operator, not only Py_EQ and Py_NE.

Code of bytes_richcompare() and PyUnicode_RichCompare() is now closer.

* cleanup bytes_richcompare()
* PyUnicode_RichCompare(): replace a test with a XOR
