* .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.
