[Aegis-developers] make transparent

[Peter M. <mi...@ca...>]

Well, I've made a start at the make transparent code.

The commands will be aemt and aemtu - my wife Mary-Therese will kill me
if I call them anything else, she says it's about time I called some
software after her.  (Much too dangerous to try to explain that I
didn't!)

Anyways you will be able to see changes appearing on SourceForge, a bit
at a time.  This thing is huge!

I spent some time today chasing through all the uses of
project_file_find &co.  These need look along the search path for file
information.  It turns out they get a new parameter to say how much or
how little search path is necessary.

view_path_none says to use the exact information available, as shallow
as possible.
view_path_simple says to honor transparency, but return the first
non-transparent file found.
view_path_extreme says to honor transparency, and to make removed files
appear as if they were not there - this results in quite a lot of lines
of code vanishing from clients of the API.

All this sleuthing also revealed a memory leak (and CPU waste) in
project_file_nth - used in about a dozen places.  I was hoping it was
the source of aenf O(n**2) behaviour (and so visable in aeimport) but it
isn't.

Anyways, if some of you could keep an eye on developments, and point out
obvious (or subtle) things I've missed, I would appreciate it.
