One Sed to Rule Them All

XMS is a generic sed that merges UMS and TMS. FMS will be done later if the POC is approved.
{U,T}MS have similar structures, which made possible to have a single MS with the following properties:
* single monitor class
* single server class
* {U,T}MS uri keys were merged into a single sed_uriAdr key
* all services are accessible from a single endpoint
There's no umssed and tmssed anymore, since some utility classes were tightly coupled to the Server class.

It has been rebased into the current master, there may be glitches.
Comments are welcome.
