we now have pe_tree_...., with permanent allocation scope.

we should use them for guid->name mappings instead of a hashtable.
(and add a file holding global wellknown mappings like manuf does for
well known ethernet prefixes)

Yes.   it would be useful with GUID->name resolution.

This could replace some of the current guid->name mappings that we do for
example for the GUIDs inside some dcerpc policyhandles and also the ones for
filename->giod tracking for smb2

There are also for dcerpc interfaces a fair number of known "magic" guids
which would be useful if they could be resolved into a name.

I think we should add a guid  file  similar to the manuf file where
well-known guid to name mappings could be stored.

since guids are "never" reused and also since we might preload the mapping
table from a file
that is why i recently changed the se_tree  code  to make it trivial to add
pe_tree_...   type.   PErmanent tree   a tree with storage scope that is
never released.

for the guid->name mapping i think we should use such a pe_tree_...   using
