Jiri Olsa 40c03ad592 tools lib traceevent: Add xen plugin
Adding xen plugin.

This plugin adds fields resolving for following tracepoint events:

  xen:xen_mc_entry
  xen:xen_mc_extend_args

The diff of 'perf script' output generated by old and new code: (data
was generated by 'perf record -e 'xen:*' ls')

  --- script.xen.old
  +++ script.xen.new

NOTE We still do not handle the 'sizeof' and fail to parse following xen
tracepoints:

  xen:xen_mmu_set_pte
  xen:xen_mmu_set_pte_atomic
  xen:xen_mmu_set_domain_pte
  xen:xen_mmu_set_pte_at
  xen:xen_mmu_set_pmd
  xen:xen_mmu_set_pud
  xen:xen_mmu_set_pgd
  xen:xen_mmu_ptep_modify_prot_start
  xen:xen_mmu_ptep_modify_prot_commit
