Kai Engert 0ccf958b45 Bug 527659, Update mozilla-central to NSS 3.12.6 (beta) 
== NSS portion
== r=rrelyea/wtc for upgrading mozilla-central to cvs tag NSS_3_12_6_BETA1
== This includes reapplying the (merged) patch from bug 519550 on top of NSS.
== PSM portion
== Includes the patch to disable TLS compression, r=kaie
== Include the patch to disable zlib test programs, which don't work on maemo, r=kaie
