[Qemu-devel] [PATCH v10 08/30] qapi: More tests of alternate output

[Eric Blake <eblake@redhat.com>]

The testsuite was only covering that we could output the 'int'
branch of an alternate (no additional allocation/cleanup required).
Add a test of the 'str' branch, to make sure that things still
work even when a branch involves allocation.

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