Some http servers will reject PUT, POST, and PATCH requests if they
do not have a Content-Length header.

Patch by James Rutherford, with additional cleaning up of the
'request' documentation by me.

As a result, explicitly support pathlib.Path objects as arguments.
Also added tests for the CLI interface.

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).

signal.sigtimedwait() if functions are missing

If Python failed, show also stdout in the assertion error.

when interrupted by a signal not in the *sigset* parameter, if the signal
handler does not raise an exception. signal.sigtimedwait() recomputes the
timeout with a monotonic clock when it is retried.

Remove test_signal.test_sigwaitinfo_interrupted() because sigwaitinfo() doesn't
raise InterruptedError anymore if it is interrupted by a signal not in its
sigset parameter.

Save and then restore errno because PyErr_CheckSignals() and
PyErr_SetFromErrno() can modify it.
