On success, it stores the file descriptor in the chardev object, and returns success. On failure, it closes the file descriptor, and returns failure. chardev_new() then passes the Chardev to object_unref(). This duly calls char_parallel_finalize(), which closes the file descriptor stored in the chardev object. Since qemu_chr_open_pp_fd() didn't store it, it's still zero, so this closes standard input. Ooopsie. To demonstate, add a unit test. With the bug above unfixed, running this test closes standard input. char_hotswap_test() happens to run next. It opens a socket, duly gets file descriptor 0, and since it tests for success with > 0 instead of >= 0, it fails. The new unit test needs to be conditional exactly like the chardev it tests. Since the condition is rather complicated, steal the solution from the serial chardev: define HAVE_CHARDEV_PARALLEL in qemu/osdep.h. This also permits simplifying chardev/meson.build a bit. The bug fix is easy enough: store the file descriptor, and leave closing it to char_parallel_finalize(). The next commit will fix char_hotswap_test()'s test for success.

When a backend's compile-time conditional QOM type is not compiled in, creation fails with "'FOO' is not a valid char driver name". Okay, except introspecting chardev-add with query-qmp-schema doesn't work then: the backend type is there even though the QOM type isn't. A management application can work around this issue by using qom-list-types instead. Fix the issue anyway: add the conditionals to the QAPI schema.
