Add core dump snapshot handler script

This is a custom core dump program that will be called when a core dump
occurs.  The program will save the core data in CORE_PATH and also, if a
root session daemon is running, will record a snapshot of tracing data
using the lttng command line utility.

Refer to README for installation and testing instructions.

Sample output of test script:

Setup...
Spawning a session daemon
Session auto-20130626-224838 created.
Kernel channel chan enabled for session auto-20130626-224838
kernel event sched_switch created in channel chan
Tracing started for session auto-20130626-224838
Sleeping...
Crashing...
./test.sh: line 35: 16980 Segmentation fault      (core dumped)
$(dirname $0)/crash
Waiting for data availability
Tracing stopped for session auto-20130626-224838
Session auto-20130626-224838 destroyed
Core dump and snapshot will be available in /tmp/lttng/{core,snapshot}.
