Release 0.8 of the User Space Tracer - UST

Tarball available at: http://lttng.org/files/ust/releases/ust-0.8.tar.gz

Major change is that the tracepoint API now takes a void *data pointer
as its first argument which must be provided when connecting the 
tracepoint. This allows multiple probes with the same function to be
connected as long as the data pointers provided are different.

 	* API CHANGE!!! Add data pointer to tracepoint probe
 	void *data is always the first argument to a tracepoint probe
 	* License LGPGv2.1 text and information added
 	* Update COPYING file
 	* Add TRACE_EVENT api proposal, not finalised
 	NOT usable at this point. Only bound to a printf.
 	ustctl command for listing trace event
 	* Multiple fixes
 	Compilation warnings
 	Value and error handling
     	Fix bugs introduce by prior commits
 	Security fix (CVE-2010-3386)
 	Add exit status for ustctl
 	Change malloc to zmalloc for most of UST
 	Remove unused code, syntax cleanup and consistency for markers
 	* New UST internal communication protocol
 	Add message headers
 	Usage of epoll
 	* New testcases
 	* Try to decrease namespace pollution
 	* Fix valgrind for sendmsg bug
 	* tracectl destructor aware of fork
