potrace: updated to 1.16

Release 1.16

This release consists of bugfixes and minor portability improvements.
A potential arithmetic overflow was fixed. Rotation angles are now
normalized to between -180 and 180. We now use binary file I/O on the
OS/2 platform. The test suite tolerances were adjusted. The
configuration option --enable-local-getopt was renamed as
--with-included-getopt. Some build system improvements. Thanks to
Henri Salo and Dave Yeo for reporting bugs and suggesting
improvements.

Log message:
graphics: Replace RMD160 checksums with BLAKE2s checksums

All checksums have been double-checked against existing RMD160 and
SHA512 hashes

Log message:
graphics: Remove SHA1 hashes for distfiles

Log message:
*: Convert broken sourceforge HOMEPAGEs back to http

Log message:
all: migrate several HOMEPAGEs to https

pkglint --only "https instead of http" -r -F

With manual adjustments afterwards since pkglint 19.4.4 fixed a few
indentations in unrelated lines.

This mainly affects projects hosted at SourceForce, as well as
freedesktop.org, CTAN and GNU.

Update potrace to 1.15.

v1.15 2017/08/05
	(2017/08/05) PS1 - use round() instead of rint()
	(2017/08/05) PS1 - portability: set both _POSIX_C_SOURCE and
	_NETBSD_SOURCE to enable strdup prototype in string.h, as
	_XOPEN_SOURCE=500 doesn't work on macOS, _XOPEN_SOURCE=600 doesn't
	work on SunOS, and _POSIX_C_SOURCE alone doesn't work on Minix.
	(2017/08/02) PS1 - fixed a potential arithmetic overflow.
	(2017/06/17) PS1 - fixed a bug with very large bitmaps. Reported
	by Michael Voříšek.
	(2017/03/05) PS1 - autoconf: added --enable-local-getopt to avoid
	using the system-wide getopt library (it may still end up being
	used on GNU systems).
	(2017/03/05) PS1 - portability: moved getopt.h to a subdirectory,
	to be included only when needed. Reported by Daniel Macks.
	(2017/03/05) PS1 - portability: use _XOPEN_SOURCE=600 to fix macOS
	warning.
	(2017/02/27) PS1 - fixed more buffer overflows (not security
	critical), including one reported by Agostino Sarubbo. This also
	fixes CVE-2017-12067.

Log message:
potrace: Set _XOPEN_SOURCE correctly.

Updated potrace to 1.14.

February 19, 2017: Release 1.14

 This release consists of bugfixes and minor portability improvements.
 A number of bugs triggered by malformed BMP files have been fixed,
 including CVE-2016-8685 and CVE-2016-8686. Error reporting has been
 improved. The image size is now truncated when the bitmap data ends
 prematurely. It is now possible to use negative dy in bitmap
 data. Portability has been improved to encompass C++11. The default
 compiler is now clang if available. Thanks to Nelson Beebe and Martin
 Gieseking for reporting portability issues, and to Agostino Sarubbo
 for reporting bugs.

Log message:
Quick fix: install the include file; remove patches

Log message:
Release 1.13
Some critical bugs in the processing of BMP files were fixed. These
bugs allowed the program to be crashed, or potentially to be abused
in other ways, by feeding it specially crafted BMP files. Thanks to
Tomasz Buchert and Agostino Sarubbo for reporting these bugs.
Portability was improved for C99 and for MSVC++. Thanks to Peter
Breitenlohner, Nelson Beebe, and Martin Gieseking for reporting
portability issues.
