Too bad, sometimes Py_FatalError() is unable to write the exception into
sys.stderr (on "AMD64 OpenIndiana 3.x" buildbot, the buildbot was probably out
of memory).
Call Py_FatalError() with a different message for the two cases (result+error,
or no result and no error).
sys.stderr
It should help to see exceptions when stderr if buffered: PyErr_Display() calls
sys.stderr.write(), it doesn't write into stderr file descriptor directly.
Py_FatalError() instead of using an assertion in debug mode. Py_FatalError()
displays the current exception and the traceback which contain more information
than just the assertion error.
I expected more users of _Py_wstat(), but in practice it's only used by
Modules/getpath.c. Move the function because it's not needed on Windows.
Windows uses PC/getpathp.c which uses the Win32 API (ex: GetFileAttributesW())
not the POSIX API.
* Display the current Python stack if an exception was raised but the exception
has no traceback
* Disable faulthandler if an exception was raised (before it was only disabled
if no exception was raised)
* To display the current Python stack, call PyGILState_GetThisThreadState()
which works even if the GIL was released
which returned an invalid result (result+error or no result without error) in
the exception message.
Add also unit test to check that the exception contains the name of the
function.
Special case: the final _PyEval_EvalFrameEx() check doesn't mention the
function since it didn't execute a single function but a whole frame.
Being able to read non-python text files is not a purpose of linecache, but it
does work and people use it. This changeset adjusts the language to make it
clear that Python files are not treated uniquely, but does not go so far as to
say reading non-python files is explicitly supported.

None on Windows.
When the file is not readable, the error occurs at open on UNIX. On Windows,
the error only occurs at the first operation on the open file. It would require
to many changes to set __context__ to an OSError for all file operations, for a
little benefit (__context__ is almost never used).
