Paul Moore 0faee34ebd policycoreutils: secon: add support for setrans color information in prompt output
This patch adds support for displaying SELinux context information in
colors defined by mcstrans(8)/secolor.conf(5).  The new behavior is
enabled through the use of the "-C/--color" option and requires the
"-P" option also be specified.

The reason for this addition is that in some situations, notably MLS,
users find it helpful to add SELinux context information to their prompt:

	# example taken from the RHEL6 CC certification bash scripts
	SEROLE=`secon -rP 2>/dev/null`
	SEMLS=`secon -lP 2>/dev/null`
	PS1="[\u/$SEROLE/$SEMLS@\h \W]\\$ "
	export PS1

With the added functionality provided by this patch we can also display
the associated color information (note the addition of the "C" option):

	SEROLE=`secon -rP 2>/dev/null`
	SEMLS=`secon -lPC 2>/dev/null`
	PS1="[\u/$SEROLE/$SEMLS@\h \W]\\$ "
	export PS1

Note that in the example above only the MLS range is colored, but the
patch does provide support for all of the color information provided
by mcstransd/secolor.conf (user,role,type,range).

Finally, one quick word on the colors themselves; the secolor.conf
configuration file allows 32-bit colors but the ANSI color coding only
allows 8-bit colors so the colors displayed by secon using the "-C"
option will be a bit lossy.

Eric Paris 468bff0952 tree: Makefiles: syntax, convert all ${VAR} to $(VAR)
This is purely personal preference.  Most of the Makefiles use $() for
Makefile variables, but a couple of places use ${}.  Since this obscured
some later Makefile changes I figured I'd just make them all the same up
front.
