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.
Round 2: use proper type (jsize) for iteration variable; whitespace.
Round 3: indentation.
