    qxl: Don't drop client capability bits
    
    interface_set_client_capabilities() copies only the first few bits,
    because it falls into a Classic C trap: you can declare a parameter
    uint8_t caps[58], but the resulting parameter type is uint8_t *, not
    uint8_t[58].  In particular, sizeof(caps) is sizeof(uint8_t *), not
    the intended sizeof(uint8_t[58]).
    
    Harmless, because the bits aren't used, yet.  Broken in commit
    c10018d6.  Spotted by Coverity.

commit 977267ebb095b6bf7897363ab4e7ced909bcbe52

    qxl: Fix SPICE_RING_PROD_ITEM(), SPICE_RING_CONS_ITEM() sanity check
    
    The pointer arithmetic there is safe, but ugly.  Coverity grouses
    about it.  However, the actual comparison is off by one: <= end
    instead of < end.  Fix by rewriting the check in a cleaner way.
