igc_xzalloc_ambig allocates memory like xzalloc but it addition
registers it as root.  When MPS starts scanning, it begins from the
roots.  That means, we are sure that the referenced objects stay alive.
In the case of ambiguous references, the objects are also pinned
(i.e. don't move).

That pinning part is not necessary for the scroll-bar case, but
igc_xzalloc_ambig is currently the easiest to use function available in
igc.h.
