wireshark/ui/gtk/decode_as_dcerpc.c
Guy Harris d7b2aad043 Move some headers for UI stuff, and the alert_box.c UI-specific file, to
the ui directory.  (Perhaps some other files that would be used by all
flavors of Wireshark, for any GUI toolkit or for someting such as
ncurses, and not for any command-line tool such as TShark, should be
moved there as well.)

Shuffle some #includes to put the "ui/XXX.h" includes together.
