[cximage] Fix denial of service via a crafted photo file (CVE-2013-1438)

Embedded CxImage embeds a copy of libDCR, a fork of dcraw.c, which
contains several denial of service vulnerabilities as discovered by
Raphael Geissert. These seem to affect the CxImage-embedded libDCR as
well.

http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2013-1438
----
Unspecified vulnerability in dcraw 0.8.x through 0.8.9, as used in
libraw, ufraw, shotwell, and other products, allows context-dependent
attackers to cause a denial of service via a crafted photo file that
triggers a (1) divide-by-zero, (2) infinite loop, or (3) NULL pointer
dereference.
----

Port the fix from libRaw [1] to CxImage copy of libDCR. The patch has
been submitted upstream.
