1cdea8b9e9 * libtiff/tif_dirread.c: fix regression of libtiff 4.0.8 in 
ChopUpSingleUncompressedStrip() regarding update of newly single-strip
uncompressed files whose bytecount is 0. Before the change of 2016-12-03,
the condition bytecount==0 used to trigger an early exit/disabling of
strip chop. Re-introduce that in update mode. Otherwise this cause
later incorrect setting for the value of StripByCounts/StripOffsets.

f2a3b02040 * .travis.yml, build/travis-ci: new files from 
0001-ci-Add-Travis-support-for-Linux-builds-with-Autoconf.patch by
Roger Leigh (sent to mailing list on 2017-06-08)
This patch adds support for the Travis-CI service.

* .appveyor.yml: new file from
0002-ci-Add-AppVeyor-support.patch by Roger Leigh (sent to mailing
list on 2017-06-08)
This patch adds a .appveyor.yml file to the top-level.  This allows
one to opt in to having a branch built on Windows with Cygwin,
MinGW and MSVC automatically when a branch is pushed to GitHub,
GitLab, BitBucket or any other supported git hosting service.

* CMakeLists.txt, test/CMakeLists.txt, test/TiffTestCommon.cmake: apply
patch 0001-cmake-Improve-Cygwin-and-MingGW-test-support.patch from Roger
Leigh (sent to mailing list on 2017-06-08)
This patch makes the CMake build system support running the tests
with MinGW or Cygwin.

1d658302f8 * libtiff/tif_swab.c: if DISABLE_CHECK_TIFFSWABMACROS is defined, do not do 
the #ifdef TIFFSwabXXX checks. Make it easier for GDAL to rename the symbols
of its internal libtiff copy.

6281927e03 * libtiff/tif_dirinfo.c, tif_dirread.c: add _TIFFCheckFieldIsValidForCodec(), 
and use it in TIFFReadDirectory() so as to ignore fields whose tag is a
codec-specified tag but this codec is not enabled. This avoids TIFFGetField()
to behave differently depending on whether the codec is enabled or not, and
thus can avoid stack based buffer overflows in a number of TIFF utilities
such as tiffsplit, tiffcmp, thumbnail, etc.
