Log:
[LDR]
- Implement support for manifest prober routine in LdrpWalkImportDescriptor, in its
simplest way
- Implement such routine in kernel32 (that's mostly a copy of Wine's
create_module_activation_context which seems to nicely correspond to what Windows does).
- As create_module_activation_context is moved into kernel32, delete it from ntdll
- Improve debug output in RTL's Activation Context implementation to ease debugging
- Now, ReactOS indeed looks for and actually loads manifests when loading modules. Thanks
to http://blog.tombowles.me.uk/2009/10/05/winsxs/ for a really good description of how
activation contexts work
