For kernel modules there is a context.stp tapset function modname that takes an
address and produces the module name. It would be convenient to have the same
for user space. function modname:string (addr: long) returns the name of the vma
of the current task in which the address was found.
I think usymdata already does part of that (and some more), although that might
only work for those VMAs we matched, umodname() should pull from the taskfinder
directly even if we didn't match.
