[SHELL32]
[BROWSEUI]
* Move undocshell.h to a shared location, and move some shared utility functions into it.
* Replace all the COM object constructor functions with generic equivalents.
* Fixes a big bunch of "problems" found by Coverity Scan, but I don't have the list of CID at the moment.

* Stop using the C defines LPSHELLFOLDER, LPSHELLVIEW and LPUNKNOWN, and use the respective C++ interfaces instead.
* Change one batch of COM interface pointers into CComPtr-based pointers, and remove associated Release calls (including at least one that was not supposed to be there at all).
* Remove a couple (repeated multiple times) pointless casts.
