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
