Hmm, I was not able to find any further examples for this mixture of
standard device syntax and special interpretation of numerical values -
even in the qemu-doc, the only place where the special case of 'port'
was mentioned.

So I still see this as a significant improvements as it
 - aligns -gdb to the standard syntax use in -monitor, -serial or
   -parallel, making the interface more intuitive
 - documents this properly

I will adjust description to clarify that this patch refactors the
existing feature into a canonical form, but does not actually add a new one.
