e2c86c71c2 Use time() instead of clock() for timeouts.
The clock() function returns the processor time used by the process. This
is not a good timeout mechanism since the code is suspended most of the
time waiting for the forked process to finish. Replace with the time()
function.

8eb25d552b dumpstate: fix dumping traces for vm processes on 64-bit
dumpstate was not dumping any stack traces for vm processes because
it was failing the string compare for /system/bin/app_process.
64-bit devices use app_process32 and app_process64 instead of
app_process, and zygote64 alongside zygote.  Change the string
matching to be prefix matching.

26288202e7 Convert all selinux_android_restorecon and _setfilecon calls to new API.
libselinux selinux_android_restorecon API is changing to the more
general interface with flags and dropping the older variants.

Also get rid of the old, no longer used selinux_android_setfilecon API
and rename selinux_android_setfilecon2 to it as it is the only API in use.

27f9e6d849 Support broadcast when dumpstate finishes.
Add flag that sends BUGREPORT_FINISHED broadcast when dumpstate
is finished, including the resulting filesystem paths.  Also reduces
directory creation to 0770.

e7b6cf13f9 Ensure dumpstate children die
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.

0c22e8b316 dumpstate: dump all threads in show_wchan
for_each_pid only finds processes and not their threads.  Add
for_each_tid and call it for show_wchan so we can see where all
threads are blocked in the kernel.

c7f1fe2680 Ensure that /data/anr/traces.txt is world-writable
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.
