[Qemu-devel] [PATCH v9 05/27] qapi: More tests of alternate output

[Eric Blake <eblake@redhat.com>]

The testsuite was only covering that we could output a built-in
branch of an alternate; make sure that things still work even
when a branch involves allocation, to ensure that we don't leak
when run under valgrind.

Update to modern style of g_new0() over g_malloc0() while
touching it.
