uname and gname field.

If tarfile creates a new archive and adds a file with a
uid/gid that doesn't have a corresponding name on the
system (e.g. because the user/group account was deleted) it
uses the empty string in the uname/gname field now instead
of "root". Using "root" as the default was a bad idea
because on extraction the uname/gname fields are supposed
to override the uid/gid fields. So, all archive members
with nameless uids/gids belonged to the root user after
extraction.

Fix Issue10012 - httplib headers, which are (sometimes mistakenly) int are explicitly cast to str (bytes - in py3k).

Also made the doc string for email._parseaddr's 'quote' function more
accurate; I'd love to make the function match the old docstring instead,
but other code uses it according the existing semantics.

 * test_aswidechar() => unicode_aswidechar()
 * test_aswidecharstring() => unicode_aswidecharstring()

UTF-16 surrogate pairs by single non-BMP characters for 16 bits Py_UNICODE
and 32 bits wchar_t (eg. Linux in narrow build).

And write unit tests for PyUnicode_AsWideChar() and PyUnicode_AsWideCharString().

This fixes a regression noticed by bzr, introduced by issue #9324.

before passing it to the system asctime.  Patch by MunSic Jeong.

Issue #9599:  Further accuracy tweaks to loghelper.  For an integer n that's small enough to be converted to a float without overflow, log(n) is now computed as log(float(n)), and similarly for log10.

And the codec name is normalized.
