[virt-tools-list] [PATCH virt-viewer] spice-xpi-client: log to SPICE_XPI_CLIENT_LOG if specified

[Marc-André Lureau]

Logging to syslog is pretty nice, but doesn't let the user easily read
it back without special rights. Instead, rely on default desktop logging
(sadly to ~/.xsession-errors, atm), and allows to redefine logging to a
file specified by SPICE_XPI_CLIENT_LOG. People who prefer keeping the
old spicec ~/.spicec/spicec.log file can set this variable in their
enviroment.
