RFR: JDK-8189263 Introduce CUSTOM_ROOT

[David Holmes]

Hi Magnus,

I find this all very confusing - we have a number of CUSTOM_* variables 
now and I would expect they to be closely tied together. Also unclear if 
TOPDIR is really the top-dir or the top of the "open" repo? If really 
the top then aren't TOPDIR and CUSTOM_ROOT the same ?? Or are we 
allowing the custom and regular parts to exist isolated in the filesystem ??

Thanks,
David
