[Qemu-devel] Add support for SystemTAP and DTrace tracing backends (v6)

An update of the SystemTAP/DTrace patches from

  http://lists.gnu.org/archive/html/qemu-devel/2010-11/msg00563.html

The first patch contains the generic DTrace tracing backend support.
The second patch contains additional pieces for SystemTAP to generate
a tapset for each of the qemu-system-XXX binaries, to simplify life
for admins wanting to use the tracing backend.

Changed in v6:

 - Fix handling of probes with no-args in DTrace provider
 - Generate one tapset per target, for both system and user
   emulators
 - Re-write command line arg parsing in tracetool so it
   doesn't assume a particular ordering of args
 - Change '-s' to '--stap' in tracetool to avoid confusion
 - Pass full binary name into tracetool
