ENH: Refactor and enhance the CI testing infrastructure

1) Improve travis build script for use outside travis.
   Allow the script used for CI builds to also be used
   locally in a similar manner to the CI use of the scrips

2) Add ctest compatible testing and CDASH support
   Report testing and building results to
   https://my.cdash.org/index.php?project=jsoncpp

   NOTE: The new ctest infrastructure is not yet robust on winodws
         Do no yet enable the new features for running test with ctest
         on windows platform.  The previous behaviors are maintainted,
         but enhance test reporting from windows is not yet supported.

3) Add a cmake coverage testing option
   Ensure that cmake builds on linux are tested.
   Ensure that code coverage is reported.

4) Move conditional environment checking into the matrix
   Avoid multiple places where conditional logic is used to
   change compiler behavior.  As more test environments are
   created fromt the travis.yml matrix, all settings should be
   obvious from that one location.

5) Tests with known regressions from the jsonchecker are suppressed
    Tests that are known to pass with jsoncpp more lenient
    syntax enforcement are exluded from tests in test/runjsontests.py

 ### Building and testing with Meson/Ninja
-Thanks to David Seifert (@SoapGentoo), we (the maintainers) now use [meson](http://mesonbuild.com/) and [ninja](https://ninja-build.org/) to build for debugging, as well as for continuous integration (see [`travis.sh`](travis.sh) ). Other systems may work, but minor things like version strings might break.
