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).
