Make raw memory access tunable
Modern systems shouldn't need direct access to raw memory
devices (/dev/mem, /dev/kmem, /dev/mergemem, dev/oldmem, /dev/port)
anymore, so let's remove the access in most cases and make it tunable
in the rest.
Add dev_read_raw_memory_cond(), dev_write_raw_memory_cond() and
dev_wx_raw_memory_cond(), which are conditional to new boolean
allow_raw_memory_access.
Remove raw memory access for a few domains that should never have
needed it (colord_t, iscsid_t, mdamd_t, txtstat_t), should not need it
anymore (dmidecode_t, Debian devicekit_diskt_t, hald_t, hald_mac_t,
xserver_t) or the domains that should transition to different domain
for this (rpm_t, kudzu_t, dpkg_t).
