lihardware_legacy was ALWAYS re-writing the
wpa_supplicant.conf file's "ctrl_interface" entry to the
value specified as the property wifi.interface, whose value
was typically "wlan0".  This was designed to allow the
wpa_supplicant service to be started with a "socket"
directive in its service description in an init.rc file.
Under these circumstances, the socket name is exchanged
between wpa_supplicant and its WifiService client through an
environment variable whose name is derived from
wifi.interface and a standard prefix.

However, since the "ctrl_interface" entry was always
re-written in this way, it broke the ability to use
"ctrl_interface" in its standard usage as a directory where
the (unix-domain) socket will be exchanged.

This change restores the ability to use the standard
directory-form ctrl_interface usage by limiting the
re-writing of the ctrl_interface entry to cases where it
does not look like an absolute path or the "DIR=" form of
directory.

setForceUse() should not force new device selection on outputs
if the selected device is 0. If a device 0 (no device) selection
is forced on a duplicated output, this causes volumes to be reset to
their default on outputs the duplicated output is connected to.

Also force reapply volumes when a new output is created. It is safer and more
explicit than relying on the fact that the selected volume is different
from default volume and thus is actually sent to audioflinger.
