Subject: r21456: Allow anonymous and non-anonymous nested
 structures/unions/enums/bitmaps to be used in the Samba 4 NDR parser.

This doesn't actually work yet as Parse::Pidl::NDR doesn't handle nested
data structures yet, but it's a first step.
(This used to be commit 8aac1fc98b812a0668bc0d803d1e2831396b455e)
