[Qemu-devel] [PATCH 06/12] cmdline: implement -localtime with QemuOpts

[Paolo Bonzini <pbonzini@redhat.com>]

The -localtime option already has a QemuOpts equivalent.  Setting
the merge_lists option on the -rtc list makes it simple to use it.

This includes a small change in behavior for -rtc.  For example, "-rtc
base=localtime -rtc driftfix=slew" will actually combine the option
rather than override them.  These are actually nicer semantics than
what was there so far.
