Consolidated the CMake project.

- Moved everything to one CMakeLists.txt
- Added support for the json_process test suites (instead of just the API
  tests).
- Changed to use the modified json_process version that does away with the
  environment variables (originally written by DanielT).
- Had to exclude "test_memory_funcs" on MSVC, since void pointer
  arithmetics are not allowed as it is done in secure_malloc and
  secure_free.
- Had to add a check for "ssize_t". This is not available on Windows and
  maybe on some other platforms (used in test_pack.c)
- Result from running ctest (The failure seems unrelated to CMake, it's
  just that the expected result is in a different order):
99% tests passed, 1 tests failed out of 121

Total Test time (real) =   1.31 sec

The following tests FAILED:
         24 - valid__complex-array (Failed)
