procutil: fix error message of tempfile filter First, we need to use procutil.system() to get an exit code compatible with explainexit(). Second, explainexit() returns (msg, code) tuple.

procutil: unify platform.explainexit() Since 4368f582c806 "use subprocess instead of os.system", posix.explainexit() is the superset of Windows implementation.

procutil: rewrite popen() as a subprocess.Popen wrapper (issue4746) (API) os.popen() of Python 3 is not the popen() we want. First, it doesn't accept command in bytes. Second, a returned stream is always wrapped by TextIO. So we have to reimplement our popen(). Fortunately, this fixes the bug 4746 since ours returns an exit code compatible with explainexit(). .. api:: ``procutil.popen()`` no longer supports text mode I/O.

procutil: always popen() in binary mode On Python 3, non-binary stream is useless. Let's convert line ending by ourselves. Note that we don't need fromnativeeol() in patch._externalpatch() since any whitespace characters are rstrip()-ed.

py3: byte-stringify test-import.t Still the test doesn't pass. # skip-blame because just adding some b''

py3: convert parsed message items to bytes in patch.extract() Appears that BytesParser() parses bytes into unicode, sigh.

py3: silence warning about deprecation of imp module Well, we could fix that, but we aren't yet to reach the state caring about deprecation on the Python 3 line. So let's silence it for now to fix tons of "minor" Py2/3 incompatibilities by relying on our test suite.
