With a XEN_DOMCTL_getdomaininfo hypercall, "flags & XEN_DOMINF_debugged" 
(or xc_dominfo_t.debugged) will tell you whether a debugger is attached 
to a domain.

This is the closest I am aware of you being able to get.

Whether gdbsx is running, or what port it is running on, are internal 
details to the domain running the debugger and not interesting to Xen.

If you can assume that all debuggers are run in dom0, then some process 
list based approach is probably best.
