Provide "Decode As" functionality through dissectors themselves instead of the GUI. Bug 9450 (https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=9450)
The basic idea behind this design is to have dissectors register with a "decode as list" with their name and dissector table. When "Decode As" dialog is launched, any "registered" dissector found in the packet will cause a tab to be created in the dialog.
This patch includes just the dissector portion of the functionality (minus packet-dcerpc.[ch] because it has hooks to the current GUI)
