Virus checkers and, on more modern Windows OSes, Windows Experience
Service, and other external processes, have been causing trouble when it
comes to tests deleting files.
On a number of occasions in the past retry logic has been added to tests
that need to delete files. Also, the jtreg harness has similar logic
when cleaning up temporary files.
This has reared its head again with:
8027902: TEST_BUG: java/net/URLClassLoader/closetest/CloseTest.java
and java/net/URLClassLoader/closetest/GetResourceAsStream.java failed
due to dir operation failed.
8022213: Intermittent test failures in java/net/URLClassLoader
I'd like to add file utility functions to the common jdk/testlibrary,
starting with a "more reliable" delete. I've made minimal changes to the
URLClassloader tests to use this ( more could be done, but this is just
a start ).

The important part here for review is the "API" and impl in FileUtils.
