Ugh, it seems that Windows doesn't even check to make sure the storage file is 
at least 24 bytes long. It looks like we were -too- good at checking for 
valid storage files.

Versus current CVS

ChangeLog:
-Move StgIsStorageFile16's implementation to StgIsStorageFile; port it to 
Win32.
-Move StgIsStorageFile from storage.c to storage32.c
-StgIsStorageFile only returns S_OK, STG_E_FILENOTFOUND, and S_FALSE (checked 
against MSDN and WinXP)
-StgIsStorageFile doesn't check if a file is large enough to be a storage 
file, it only checks for the presence of the 8-byte magic (checked against 
WinXP)
