7006126: (fs) Updates to file system API (1/2011)

[Alan Bateman]

Just to follow-up on last week's mail [1].

The webrev with the changes is here:
  http://cr.openjdk.java.net/~alanb/7006126/

On first glance it might seem a lot but most of the changes is 
refactoring/moving the methods and so it looks more than it really is. 
In particular, the changes to AbstractFileSystem from L65 is mostly just 
moved from AbstractPath. The "new" code in UnixFileSystem from L400 
onwards was moved from UnixPath. The "new" code in WindowsFileSystem 
from L315 onwards was moved from WindowsPath. In Files then the bulk of 
the "additions" were in Path previously with most of the new code at 
L2250 onwards.

Partial reviews are welcome (just let me know which files/areas you have 
reviewed so that I can keep track).

Thanks,

Alan.
