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).

Retry: forgot to include attribute mmap_low_domain_type attribute to domain_mmap_low() :
Inspired by similar implementation in Fedora.
Wine and vbetool do not always actually need the ability to mmap a low area of the address space.
In some cases this can be silently denied.
Therefore introduce an interface that facilitates "mmap low" conditionally, and the corresponding boolean.
Also implement booleans for wine and vbetool that enables the ability to not audit attempts by wine and vbetool to mmap a low area of the address space.
Rename domain_mmap_low interface to domain_mmap_low_uncond.
Change call to domain_mmap_low to domain_mmap_low_uncond for xserver_t. Also move this call to distro redhat ifndef block because Redhat does not need this ability.
