Introduce qemu_get_boot_opts()

Hi Markus,

This series introduces qemu_get_boot_opts(), in much the same way as was done for qemu_get_machine_opts().

As usual, I have out-of-scope and out-of-tree usages :) But P3 does clean up the three existing instances of the long-and-awkward form of this query and makes the one in vl.c consistent with an immediately surrounding qemu_get_machine_opts().

changed since v2:
Rebase for qemu_get_opts_singleton (Pao review).
Elaborated P3 commit message (Markus review).
changed since v1:
Fix nvram usages as well (Markus review).

Regards,
Peter
