Rationalise debugger stuff in the tree. Within Xen itself, remove PDB references and fold into domu_debug. When domu_debug hits a breakpoint, it pauses all vcpus of the domain and raises VIRQ_DEBUGGER (not VIRQ_PDB). The debugger in domain0 can either poll pause status or bind to VIRQ_DEBUGGER. Before debugging a breakpointed domain the debugger should issue PAUSEDOMAIN itself, or it is not guaranteed to see paused state of the domain! Outside Xen there's a new dir tools/debugger, containing gdb, pdb and a new library libxendebug (used by pdb). I also think the ptrace functions in libxc also ought to be moved out: either to libxendebug or to a new library libxenptrace. Signed-off-by: Keir Fraser <keir@xensource.com>
