test_resource calls resource.setrlimit() to change the file size limits.
This fails on Cygwin, which supports setrlimit() and getrlimit(), just not
changing that particular setting. (The same would apply to any other
platform that has those functions but not that particular feature.)
Since getrlimit() works and setrlimit() can be used for other reasons, a
check for ValueError was added to that part of the test.
imports e.g. test_support must do so using an absolute package name
such as "import test.test_support" or "from test import test_support".
This also updates the README in Lib/test, and gets rid of the
duplicate data dirctory in Lib/test/data (replaced by
Lib/email/test/data).
Now Tim and Jack can have at it. :)
Also add a test that Python doesn't die with SIGXFSZ if it exceeds the
file rlimit. (Assuming this will also test the behavior when the 2GB
limit is exceed on a platform that doesn't have large file support.)
