Make XRRGet*Property() always initialize returned values
Avoids memory corruption and other errors when callers access them
without checking to see if the calls returned an error value.
Callers are still required to check for errors, this just reduces the
damage when they don't.

integer overflow in XRRQueryOutputProperty() [CVE-2013-1986 1/4]
rep.length is a CARD32, while rbytes was a signed int, so
rbytes = sizeof (XRRPropertyInfo) + rep.length * sizeof (long);
could result in integer overflow, leading to an undersized malloc
and reading data off the connection and writing it past the end of
the allocated buffer.

Replace deprecated Automake INCLUDES variable with AM_CPPFLAGS
Excerpt https://lists.gnu.org/archive/html/automake/2012-12/msg00038.html
- Support for the long-deprecated INCLUDES variable will be removed
altogether in Automake 1.14. The AM_CPPFLAGS variable should be
used instead.
This variable was deprecated in Automake releases prior to 1.10, which is
the current minimum level required to build X.

Constify a couple string arguments that are just copied, not modified
Fixes compiler warnings when building app/xrandr:
xrandr.c: In function ‘crtc_set_transform’:
xrandr.c:1459:9: warning: passing argument 4 of ‘XRRSetCrtcTransform’
discards qualifiers from pointer target type
X11/extensions/Xrandr.h:419:1: note: expected ‘char *’ but argument is of
type ‘const char *’
