Please review: 7029048: LD_LIBRARY_PATH launcher changes

[Kumar Srinivasan]

Hello core-libs friends,

Background:
Earlier in the jdk7 development  setting of LD_LIBRARY_PATH was purged
in the launcher, this is a good thing!, Joe has an excellent blog which 
explains
the rational etc. etc. here:
http://blogs.sun.com/darcy/entry/purging_ld_library_path

More background:
Unfortunately!, the library versioning  that Kelly proposed earlier on 
build-dev,
<attached here for reference >  is infeasible  for jdk7, though this is 
the correct
approach.

Thus the  approach contained here, allows us to provide a transitional 
path to the
version scheme in the future. This is also the reason, the c-code is 
encapsulated
within a conditional and the test has been separated, such that these 
can be jettisoned
when required.

This explains the current proposed fix:

The old changeset for reference:

Thanks
