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 a
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 pe_tree_[insert|lookup]_array.

Log:
various UUID/GUID based changes.

I think I've changed all corresponding appearances from FT_STRING to FT_GUID, so assert the FT_ type as it should only be a FT_GUID now.

Add a generic implementation in guid_utils.h to have a way to store data about GUID to name resolving (something like value_string for e.g. int). It might be better to have a single registry for all GUID's of all dissectors and implement the GUID name resolving into the proto_tree_add... functions.
