Change nss_revision from r159459 back to r158129.

Change nss_revision from r159459 back to r158129.

This reverts r158841: Update nss_revision to 158748 to pick up NSS 3.14
pre-release snapshot 2012-09-25.

But it also reverts r159462 by thakis: Merge

rsleevi,thakis: please review.

thakis: we need to downgrade nss_revision to see if it fixes
a crash (http://crbug.com/153281). Unfortunately this will
also revert your clang -Wtautological-constant-out-of-range-compare
warning fix for NSPR (http://crbug.com/151927). Is that OK?

lgtm.

Let me know if this helps. If it doesn't and fixing nspr will take a while, is
it possible to revert the nss update in deps and roll forward to that? ('cause
if I can't roll deps forward for nss, I can't even disable the new clang warning
just for nss.)
