* prj.ads, prj.adb: (Project_Data): Add new component Display_Name
* prj-part.adb (Parse_Single_Project): Set the location of a project
on its defining identifier, rather than on the reserved word "project".
* prj-proc.adb (Expression): Adapt to the fact that default of external
references may be string expressions, not always literal strings.
(Recursive_Process): Set Display_Name equal to Name
when Location is No_Location, that is when there is no actual file.
Get the Display_Name of the project from the source, when it is not a
virtual project.
(Process): Use the Display_Name in error messages
* prj-strt.adb (External_Reference): Allow default to be string
expressions, not only literal strings.
