Send one "deselect all items" notification on selection change for LVS_OWNERDATA listviews instead of notifying about each individual item change.

Please add a separate test for this. Select and then deselect all items instead of mixing it with other tests.
Maybe the comment needs to be better. Deselect all (-1) is the ONLY signal ever sent on ANY deselection, be it one or multiple items (for LVS_OWNERDATA). This is how win32 implements it, hence there is no way of making this a separate test.
Maybe the line should read:
/* Always send one deselect all (-1) notification for LVS_OWNERDATA style instead of * informing individual items of deselection */
And I am still looking into the other remarks. Some might need reordering as I won't be able to enable the tests without this last patch.
Thanks for the feedback so far!
I was thinking adding a test that selects items, and them maybe send a mouse click somewhere in the blank space of the listview control to deselect them all to show that only a -1 notification is sent. But it may be difficult to get the tests work reliably. If you can't make it work, I guess mixing it with other tests is okay.
We do not need mouse clicks. See my reply to your comment in 1/6. The deselect of multiple items can be triggered by selecting multiple holding shift, releasing shift and moving the cursor again. This deselects multiple. The code testing for this is already in 1/6.
My comment was with regards to enabling the tests individually. I might be able to do so by reordering and spitting some of the patches.
