016a62
Instead of re-using the get_opt_name() method from QemuOpts to split a
016a62
string on ':', just use g_strsplit().

RHEL8 notes:
016a62
016a62
- Fix up upstream's obviously garbled UTF8 sequences in Dan's name (Author
016a62
  meta-datum, Signed-off-by tags).
016a62
016a62
- Harmless context difference due to downstream-only commit 8b53513834e6
016a62
  ("Use kvm by default", 2018-04-24).
