gdi32/tests: win9x doesn't return the correct number of colours used with dib sections created via DIB_PAL_COLORS.

sane.ds: Add fixmes for the last 2 unsupported capabilities; this now makes the code have fixmes for all known issues.

sane.ds: Remove large chunks of stubbed optional functionality; if it's optional, we don't have to support it, and it is not a stub.

EM_SETCHARFORMAT can be used to make text links.  Automatic URL
detection being enable would cause these links to be removed if the text
is not a URL, so this must be prevented.

Previously checks were made for AutoURLDetect_bEnable before calling
ME_UpdateSelectionLinkAttribute, or ME_UpdateLinkAttribute.  This is
more error prone than checking for this within the function, so one call
was missing this check.

ME_SetCursor also didn't respect this behaviour, since it wouldn't set
the cursor to the hand when hovering over a link without automatic URL
detection disabled.

Move to using type_basic_get_type in other files where appropriate.

widl: Fix a memory leak in the server/stub code when unmarshalling pointers to strings at the top level.

It is necessary for the first pointer to have an offset to a second
pointer instead of directly to the string type, since the second
pointer frees the memory for the string.

Avoid changing the details of a pointer once created.
Properly determine the pointer type for arrays.
