Solaris 9 does not allow USCSICMD ioctls for non-root users on vold devices
any more; they are failing with an EPERM "permission denied" error. Now, only
root is allowed to run USCSICMD ioctls on vold devices.
Fortunatelly there's a new subroutine exported from libsmedia.so
(smedia_uscsi_cmd) which allows non-root users to perform user mode SCSI
commands on a vold device. (This works with a help of a daemon running as
user root, /usr/lib/smedia/rpc.smserverd)
This change detects the presence of function "smedia_uscsi_cmd" in library
libsmedia.so at runtime, and uses this function if it's found (i.e. on
solaris 9 smedia_uscsi_cmd() is used to execture user mode scsi commands).
On solaris 8 or older, "smedia_uscsi_cmd" is not available and the code
falls back to the old ioctl(.. USCSICMD ..) method.
