Config rewrite part I (there might be two)

[Andrew Cagney <cagney at redhat dot com>]

Hello,

I've changed the way frysk.Config works so that all code - both test and 
install code only needs to refer to frysk.Config for paths.  This 
eliminates the need for frysk.junit.Paths and the need to be setting 
lots of paths as part of startup.  Most changes are straight forward, 
for instance:

 old: frysk.junit.getExecPrefix ()
 new: Config.getPkgLibDir ()

The under-the-bonnet difference is that Config is implemented as an 
object, and can be set to different configuration alternatives at 
runtime.  funit and TestRunner will use this, but nothing else should.

I've tested it fully within the build tree, but am still double checking 
all the install tree cases.

Part II, if it happens, would involve changing everything to a File from 
a String - the "Java" way of handling paths.

Andrew

PS: This means that the path Config.getBinDir() is available for Expect 
like testing of fstack et.al.
