[Qemu-devel] [PATCH v5 25/28] qapi: Drop tests for inline nested structs

[Eric Blake <eblake@redhat.com>]

A future patch will be using a 'name':{dictionary} entry in the
QAPI schema to specify a default value for an optional argument;
but existing use of inline nested structs conflicts with that goal.
This patch fixes the testsuite to avoid inline nested types, by
breaking the nesting into explicit types; it means that the type
is now boxed instead of unboxed in C code, but makes no difference
on the wire.  When touching code to add new allocations, also
convert existing allocations to consistently prefer typesafe
g_new0 over g_malloc0.
