This is copied from the namesake distutils command; there is no
automated test, so buildbots won’t call for my head this time, but it
should be okay as Python 3 users have tested the distutils command.

In dry-run mode, packaging commands should log the same info as in real
operation and should collect the same files in self.outputs, so that
users can run a command in verbose and dry-run mode to see exactly what
operations will be done in the real run.

Original patch by Filip Gruszczyński.

New tests were added in test_metadata and old tests inherited from
distutils were still in test_dist, so I moved them into test_metadata
(except for one which was more at home in test_run) and merged
duplicates.

I also added some skips to lure contributors <wink>, optimized the
Metadata.update method a trifle, and added notes about a number of
issues.

A note: The tests in test_dist used to dump the Metadata objects to a
file in the METADATA format and look for strings in its contents; I
updated them to use the mapping API of Metadata instead.  For some
fields with special writing rules, I have added tests to ensure my
conversion did not lose anything.

I have tests to add in this file and it’s always nice to start from a
clean base.

Also fix some markup and typos.

atime and mtime with nanosecond precision on modern POSIX platforms.

configure.in: Set _POSIX_C_SOURCE to 200809L, instead of 200112L, to activate
features from IEEE Stds 1003.1-2008.

configure: Set _XOPEN_SOURCE to 700, instead of 600, to get POSIX 2008
functions on OpenBSD (e.g. fdopendir).

PyLong_AsDouble() and PyLong_AsUnsignedLongLong() now raise TypeError (rather
than SystemError) when passed a non-integer argument, matching the behavior of
all the other PyLong_As*() functions.

instead of void*

<sched.h> is available (most notably on OpenBSD when built without pthread):
add an explicit configure check.

Skip the test if the function is missing. Use U+0061 (a) instead of U+00E9 (é)
because U+00E9 raises a _curses.error('unget_wch() returned ERR') on some
buildbots. It's maybe because of the locale encoding.

 - Fix PyUnicode_AsWideCharString() doc: size doesn't contain the null
   character
 - Fix spelling of the null character

Fix also spelling of the null character.

Push a character so the next get_wch() will return it.

sys.platform is now always 'linux2' on Linux (even on Linux 3)
