Attachment: fix

There's some trickiness in this test, especially with shaders and programs.  Deleting a program that's current only flags it for deletion after it's no longer current -- it's still supposed to return "true" from isprogram until that happens.  Deleting a shader only actually deletes it after it is no longer attached to any programs.  (Actually deleting a program detaches all shaders.)

This keeps track of the attachment count, and also uses a normal refptr for the current program (deleting it doesn't remove it from the current state, like the others).

Attachment: additional patch

this fixes a number of other tests that were checking similar shader/program deletion bits.  It applies on top of the previous patch -- turns out that just changing the semantics of what's considered Deleted to take into account pending delete and attachments does the right thing.
