Many functions now support "dir_fd" and "follow_symlinks" parameters;
some also support accepting an open file descriptor in place of of a path
string. Added os.support_* collections as LBYL helpers. Removed many
functions only previously seen in 3.3 alpha releases (often starting with
"f" or "l", or ending with "at"). Originally suggested by Serhiy Storchaka;
implemented by Larry Hastings.
There is a rare edge case where the filesystem used by the tempfile functions
(usually /tmp) doesn't support xattrs while the one used by TESTFN (the current
directory, so likely to be below /home) does. This causes the xattr related
test_shutil tests fail. skip_unless_xattr now checks both.
I have also added skip_unless_xattr to __all__ where it has been missing.
This helper was changed to work with any object instead of only modules
(or technically something with a __name__ attribute, see code in 3.2)
but the message stayed as is.
Windows does set the errno attribute to ENOENT, but the error message
displays the Windows error number (3 -> ERROR_PATH_NOT_FOUND), not the
errno number (2 -> ENOENT).
The Unix errno corresponding to 3 is ESRCH, explaining the confusion,
which can be seen in the following snippet:
>>> shutil.rmtree("foo")
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "Z:\default\lib\shutil.py", line 272, in rmtree
onerror(os.listdir, path, sys.exc_info())
File "Z:\default\lib\shutil.py", line 270, in rmtree
names = os.listdir(path)
WindowsError: [Error 3] The system cannot find the path specified:
'foo\\*.*'
>>> e = sys.last_value
>>> e.errno
2
>>> e.winerror
3
>>> errno.errorcode[2]
'ENOENT'

* Use str.startswith(tuple): I didn't know this Python feature, Python rocks!
* Replace sometimes sys.platform.startswith('linux') with
sys.platform == 'linux'
* sys.platform doesn't contain the major version on Cygwin on Mac OS X
(it's just 'cygwin' and 'darwin')
with the `-m` (or `--match`) option. This works with all test cases
using the unittest module. This is useful with long test suites
such as test_io or test_subprocess.

We don't need to create a temporary buffered binary or text file object just to
create an empty file.
Replace also os.fdopen(handle).close() by os.close(handle).
