[Spice-devel] [PATCH spice-common] log: Use proper format attribute for spice_log

[Frediano Ziglio]

SPICE_ATTR_PRINTF uses __printf__ format attribute.
spice_log internally uses g_string_append_vprintf which uses
G_GNUC_PRINTF attribute.
G_GNUC_PRINTF can be __printf__ or gnu_printf format which in
some systems (currently Windows) can be different.
GLib 2.58 changed G_GNUC_PRINTF on Windows from using __printf__
attribute to gnu_printf.
To avoid problems in the future uses G_GNUC_PRINTF instead of
SPICE_ATTR_PRINTF for spice_log.
