Finish fixing Zygote descriptor leakage problem

In order to prevent Zygote descriptors from leaking into the child
environment, they should be closed by the forked-off child process
before the child switches to the application UID.  These changes close
the descriptors via dup2(), substituting a descriptor open to
/dev/null in their place; this allows the Zygote Java code to close
the FileDescriptor objects cleanly.

This is a multi-project change: dalvik, art, libcore, frameworks/base,
and external/sepolicy are affected.  The CLs need to be approved
together, lest the build break or the software fail to boot.

Remove old fork-and-specialize API

As promised, this is the cleanup patch-set which removes the
old native "fork and specialize" API, which has been replaced
by a slightly-enhanced one which can close the Zygote socket
descriptors in the Zygote child.

Dalvik : Increase the upper limit check for DexOpt Deps table

Increasing upper limit check for the Deps table as additonal
jars added causes the dalvik to crash while performing dexopt
on cached jar files. This is needed for passing cts test case
which is part of libcore.java.util.jar.DalvikExecTest class

Revert "Change exception message for ArrayStoreException."

Fix all the libcore.java.lang.ArrayStoreExceptionTest failures. Why
are we pulling cosmetic changes from master?
