mcstransd never implemented this permission. To keep permission indices
lined up, replace the permission with "unused_perm" to make it clear that
it has no effect.
Remove complement (~) and wildcard (*) in allow rules so that there are no
unintentional additions when new permissions are declared.
This patch does not add or remove permissions from any rules.
In glibc, the get_nprocs method reads /sys/devices/system/cpu/online, so
we need to grant most domains read access to this file. As we don't want
them to have read access on sysfs_t by default, create a new type
(cpu_online_t) and assign it to the file, and grant domains read access
to the file.
This does require systems to relabel the file upon every boot, something
distributions do in their bootup scripts, as /sys devices don't keep
their context.

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.
