[Spice-devel] [spice v1 4/8] tests: migrate: cosmetic changes on start_qemu()

[Victor Toso]

From: Victor Toso <me at victortoso.com>

This function can be tweak quite a bit due all possibilities around
QEMU configuration. This patch removes incoming_args and extra_args
and move their values to the right place in the function.

I'm also applying a more extensive coding style for parameters, so
when we need to do changes it should happen with fewer lines.
