Use prctl(PR_SET_PDEATHSIG, SIGKILL) in each forked child to ensure
it dies when dumpstate dies.
This is important for two cases:
- dumpstate runs a timer for each child process. On expiration, it
sends SIGTERM to kill the process. Sometimes SIGTERM isn't enough
to kill a hung process, so the child lives on.
- When dumpstate is killed by the user before completing, outstanding
children continue to run and generate output.

Dump /d/extfrag/unusable_index in bugreports. It shows the
percentage of memory in each zone that is not available for
allocations for each order.

When "adb bugreport" was run on previous adb releases, it
called "adb shell dumpstate". In later versions of Android,
this was changed to "adb shell bugreport", which starts
the dumpstate service.
Modify the dumpstate command so that it calls bugreport
when it's not running as root. This allows both
"adb shell dumpstate" and "adb shell bugreport" to have
the exact same output.

The newer kernels now have /proc/net/xt_qtaguid/iface_stat_fmt.
Add the extra iptables output and remove ip6tables for nat which doesn't
exist.

adb bugreport > b & sleep 5; kill $?
will show that a bunch of tools will SIGPIPE when trying to output data
which is normal.
We don't have a way on linux (bsd yes), to set NOSIGPIPE on the file desc
passed down via fork/exec.

The umask changed for init. We have to force /data/anr to be world
readble and /data/anr/traces.txt to be world writable so dalvik
processes can write to it.
Hopefully this is a short term change while we investigate tightening
up these permissions.
