* prj-proc.adb, make.adb, mlib-prj.adb, prj.adb, prj.ads, makeutl.adb,
clean.adb, prj-nmsc.adb, prj-env.adb, prj-env.ads (Project_Data.Seen):
field removed. This is not a property of the
project, just a boolean used to traverse the project tree, and storing
it in the structure prevents doing multiple traversal in parallel.
(Project_Data.Checked): also removed, since it was playing the same role
as Seen when we had two nested loops, and this is no longer necessary
(For_All_Imported_Projects): removed, since in fact there was already
the equivalent in For_Every_Project_Imported. The latter was rewritten
to use a local hash table instead of Project_Data.Seen
Various loops were rewritten to use For_Every_Project_Imported, thus
removing the need for Project_Data.Seen. This avoids a lot of code
duplication
