6d4cd40868 qemu-option: Fix qemu_opts_set_defaults() for corner cases
Commit 4f6dd9a changed the initialization of opts in opts_parse() to
this:

    if (defaults) {
        if (!id && !QTAILQ_EMPTY(&list->head)) {
            opts = qemu_opts_find(list, NULL);
        } else {
            opts = qemu_opts_create(list, id, 0);
        }
    } else {
        opts = qemu_opts_create(list, id, 1);
    }

Same as before for !defaults.

If defaults is true, and params has no ID, and options exist, we use
the first assignment.  It sets opts to null if all options have an ID.
opts_parse() then returns null.  qemu_opts_set_defaults() asserts the
value is non-null.  It's the only caller that passes true for
defaults.

To reproduce, try "-M xenpv -machine id=foo" (yes, "id=foo" is silly,
but it shouldn't crash).

I believe the function attempts to do the following:

    If options don't yet exist, create new options
    Else, if defaults, modify the existing options
    Else, if list->merge_lists, modify the existing options
    Else, fail

A straightforward call of qemu_opts_create() does exactly that.

96bc97ebf3 qemu-option: Fix qemu_opts_find() for null id arguments
Crashes when the first list member has an ID.  Admittedly nonsensical
reproducer:

$ qemu-system-x86_64 -nodefaults -machine id=foo -machine ""

376609cc6c qemu-option: Add qemu_opts_absorb_qdict()
This adds a function that adds all entries of a QDict to a QemuOpts if
the keys are known, and leaves only the rest in the QDict.

This way a single QDict of -drive options can be processed in multiple
places (generic block layer, block driver, backing file block driver,
etc.), where each part picks the options it knows. If at the end of the
process the QDict isn't empty, the user specified an invalid option.

7216ae3d1a qemu-option: Disable two helpful messages that got broken recently
commit 8be7e7e4 and commit ec7b2ccb messed up the ordering of error
message and the helpful explanation that should follow it, like this:

    $ qemu-system-x86_64 --nodefaults -S --vnc :0 --chardev null,id=,
    Identifiers consist of letters, digits, '-', '.', '_', starting with a letter.
    qemu-system-x86_64: -chardev null,id=,: Parameter 'id' expects an identifier

    $ qemu-system-x86_64 --nodefaults -S --vnc :0 --machine kvm_shadow_mem=dunno
    You may use k, M, G or T suffixes for kilobytes, megabytes, gigabytes and terabytes.
    qemu-system-x86_64: -machine kvm_shadow_mem=dunno: Parameter 'kvm_shadow_mem' expects a size

Pity.  Disable them for now.
