With the upgrade of buildbot.python.org from Buildbot 0.8.x to 0.9.x,
the xmlrpc interface has been removed.  This test is now skipped until
it can be rewritten to query a suitable substitute.

Patch by Jon Dufresne.

requires them.  Disable executable bits and shebang lines in test and
benchmark files in order to prevent using a random system python, and in
source files of modules which don't provide command line interface.  Fixed
shebang lines in the unittestgui and checkpip scripts.

time.xmlrpc.com has come and gone over the years, and has been gone again for
a while.  The test did test one thing that the current xmlrpc tests don't: the
use of multiple levels of attribute names in the call.  So in addition to
removing the network test, we add a test in xmlrpc of dotted name access.

There should also be a test for when dotted name access is disallowed, but
that requires more extensive test harness refactoring, and in any case was not
tested by the network test we are deleting, since it is a server-side setting.

This is a slightly simplified version of a patch by Vajrasky Kok.
