[omniORB] VisiBroker x Omni: Modules and Tie implementations

[Philippe de M. Sevestre]

Hi again,

Thanks for your support. 
Using  -Wbtf works fine for this (So, this is what "flattened tie" means,
duh...).

BTW, other issues that arose in this particular project where:

- stubs/skeletons/header conventions for idl compiler generated code:
	Visi splits the code into _s and _c files. I think that the spec should be
a bit
	more restrict in this aspect, but this issue is workable using some
makefile sorcery.

- Omni tie classes for interfaces with inout string parameters use the
CORBA::String_INOUT_arg
