cryptnet: Set cache expiration time of objects that have an expiration time to the object's expiration time, rather than relying on the HTTP Expires header.

wininet: Don't call URL_LocalFileNameToPathA when asked for a unicode string and URL_LocalFileNameToPathW fails.

wininet: Trace the cache file entry's local file name rather than the passed-in cache entry info's local file name, as the caller may have passed a NULL pointer.

wininet: Fix crash when calling HttpQueryInfoA/W(HTTP_QUERY_RAW_HEADERS) before any response has been received from a server.

All of the tested functions return BOOLs, not DWORDs so use res instead of rc.

Add tests for this.

wined3d: Print an error when drawStridedSlow() is called with 0 idxSize and non-NULL idxData (CID 509).

oleaut32: In variants check bOverflow to make sure not to accidently overun static buffers in an overflow case (Coverity 313).

The simplification was bad, native msxml works if interface pointers
to the wrong interface are passed in. Tests included.

This should fix the heap corruption that caused intermittent crashes
for patchwatcher.
