msi: OriginalDatabase is the fully-expanded path to the original package if the package is local and installed from the command line.

msi: If the package is a URL, the OriginalDatabase property should be the URL and the DATABASE property should be the path to the local temporary package.

The RPC runtime could use some of the parameters, expecting them to be 
initialised.

svchost: Add a FIXME for an undocumented function (SvchostPushServiceGlobals) that some native services expect to be called by native svchost.

ole32: Determine the destination for the COM call and initialise the necessary parameters in ClientRpcChannelBuffer_GetBuffer instead of ClientRpcChannelBuffer_SendReceive.

The parameters are then freed in the matching 
ClientRpcChannelBuffer_FreeBuffer function.

widl: Make the offset of conformant string types point to the start of the conformant string format chars, not the pointer type.

Otherwise, writing a type at top-level could cause the pointer format 
string to be used in non-top-level places which may cause memory 
corruption during freeing.
