Add a "smash-stack" option to crasher.

bionic's __stack_chk_fail was preventing debuggerd from dumping
stacks, which was not helpful.

init.rc: allow IPPROTO_ICMP support

Allow userspace programs to create IPPROTO_ICMP sockets.

This socket type allows an unprivileged program to safely
send ICMP_ECHO messages and receive the corresponding
ICMP_ECHOREPLY messages, without relying on raw sockets or
setuid programs.

Please see http://lwn.net/Articles/443051/ for details.

In particular, this allows us to use a version of ping
which doesn't have any capabilities
(https://android-review.googlesource.com/52072).
In addition, this allows us to safely implement an IPv4 ICMP
based version of InetAddress.isReachable()
(https://code.google.com/p/android/issues/detail?id=20106)

Add support for filesystem capabilities.

Modify android_filesystem_config.h and add a capabilities
field. This field can be used to add filesystem capabilities
to a particular file.

android_filesystem_config.h: change ping and run-as

/system/bin/ping no longer requires CAP_NET_RAW, as we're now
using IPPROTO_ICMP. Please see the following for more details:

* http://lwn.net/Articles/443051/
* https://android-review.googlesource.com/52090
* https://android-review.googlesource.com/52072

We can now make ping a normal, unprivileged program.

/system/bin/run-as only requires CAP_SETUID and CAP_SETGID.
Explicitly set the capabilities of this file, and remove
the setuid bit.

This is equivalent to running the following commands:

  * chmod 750 /system/bin/run-as
  * chown root:shell /system/bin/run-as
  * setcap cap_setgid,cap_setuid+ep /system/bin/run-as
