Fixes the following security vulnerabilities:
- CVE-2018-17961: Artifex Ghostscript 9.25 and earlier allows attackers to
bypass a sandbox protection mechanism via vectors involving errorhandler
setup. NOTE: this issue exists because of an incomplete fix for
CVE-2018-17183.
- CVE-2018-18284: Artifex Ghostscript 9.25 and earlier allows attackers to
bypass a sandbox protection mechanism via vectors involving the 1Policy
operator.
- CVE-2018-19409: An issue was discovered in Artifex Ghostscript before
9.26. LockSafetyParams is not checked correctly if another device is
used.
- CVE-2018-19475: psi/zdevice2.c in Artifex Ghostscript before 9.26 allows
remote attackers to bypass intended access restrictions because available
stack space is not checked when the device remains the same.
- CVE-2018-19476: psi/zicc.c in Artifex Ghostscript before 9.26 allows
remote attackers to bypass intended access restrictions because of a
setcolorspace type confusion.
- CVE-2018-19477: psi/zfjbig2.c in Artifex Ghostscript before 9.26 allows
remote attackers to bypass intended access restrictions because of a
JBIG2Decode type confusion.

Fixes the following security issues:
- CVE-2018-16543: In Artifex Ghostscript before 9.24, gssetresolution and
gsgetresolution allow attackers to have an unspecified impact
- CVE-2018-17183: Artifex Ghostscript before 9.25 allowed a user-writable
error exception table, which could be used by remote attackers able to
supply crafted PostScript to potentially overwrite or replace error
handlers to inject code.

GHOSTSCRIPT_FONTS_TARGET_DIR is set to $(TARGET_DIR)/usr/share/fonts/gs
in ghostscript-fonts.mk. If we pass this full path to ghostscript, it
will look for fonts in $(TARGET_DIR), which doesn't exist on the
target.
Instead of /usr/share/fonts/gs, use /usr/share/fonts so ghostscript can
also access other fonts than the ones installed by ghostscript-fonts.

We want to use SPDX identifier for license string as much as possible.
SPDX short identifier for AGPLv3 is AGPL-3.0.
This change is done using following command.
find . -name "*.mk" | xargs sed -ri '/LICENSE( )?[\+:]?=/s/AGPLv3/AGPL-3.0/g'

The ijs/ subfolder contains a bogus ltmain.sh file, which is actually a
broken symbolic link. Due to this, our logic to patch ltmain.sh files
fail with some patch versions:
>>> ghostscript 9.21 Patching libtool
File /home/buildroot/build/instance-0/output/build/ghostscript-9.21/ijs/ltmain.sh is not a regular file -- refusing to patch
Since we are anyway not using the ijs support (--without-ijs is passed),
do like we do for all other sub-components of ghostscript: get rid of
the ijs/ subfolder completely.

[Thomas:
- switch to version 9.21 now that it has been released
- add a hash file
- switch to Git formatted patches
- use $(HOSTCC) instead of hardcoding "gcc", and use $(HOST_CFLAGS) and
$(HOST_LDFLAGS) instead of hardcoding -L$(HOST_DIR)/usr/lib
-I$(HOST_DIR)/usr/include
- add entry to DEVELOPERS file.]
