getaddrinfo takes an exclusive lock on some platforms, causing clients to queue
up waiting for the lock if many names are being resolved concurrently. Users
may want to handle name resolution in their own code, for the sake of caching,
using an alternate resolver, or to measure DNS duration separately from
connection duration. Skip getaddrinfo if the "host" passed into
create_connection is already resolved.

Patch by A. Jesse Jiryu Davis.
In Python 2, these were duplicated; one for urllib.urlopen() and one for
urllib2.urlopen(). The test_urllibnet version has a better precondition to
avoid false failures with bad DNS, and the test_urllib2_localnet version had
a more up-to-date comment and domain name.
APIs into a note that mlsd() is a nicer API if the server supports
it. They aren't deprecated, they are all different server commands.
Not all servers support all commands.

This fixes a test failure in refleak mode because
test_property_decorator_doc_writable no longer modifies
the class in module level.
Initial patch by Nan Wu and Torsten Landschoff (from issue 25757)
The previous fix only handled the case of the parent package of __main__
failing to initialize.
Also make the "Error while finding spec" formatting slightly more appealing,
and document and test that the module name must be absolute.
Also document that the separate functions that delete objects are preferred;
using PyObject_SetAttr(), _SetAttrString(), and PySequence_SetItem() to
delete is deprecated.
