This is because it's really easy to get a name collission if compiling
Jansson as a subproject in a larger CMake project. If one project includes
several subprojects each having their own config.h, this will cause the
wrong file to be loaded.
Since len is known, the copy function does not need to check byte by byte
the end of the string.

When building a "MinSizeRel" with CMake I get a compilation error in lex_unget_unsave. This is because assertions are turned off using -DNDEBUG:
```
/usr/bin/gcc -DHAVE_CONFIG_H -fPIC -Os -DNDEBUG -Ijansson/build/include -Ijansson/build/private_include -Wall -Wextra -Wdeclaration-after-statement -Werror -o CMakeFiles/jansson.dir/src/load.c.o -c jansson/src/load.c
jansson/src/load.c: In function âx_unget_unsaveâjansson/src/load.c:256:14: error: variable â set but not used [-Werror=unused-but-set-variable]
cc1: all warnings being treated as errors
```
This will then remove the insert, which makes the "d" variable unused, which is treated as an error since we have -Wall set. We can't simply get rid of the variable either and put the strbuffer_pop call in the assert call, since it's a macro and would remove the call entirely. So I simply added a check for NDEBUG to fix it.
- 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)
Added multiple CMake-related files to project.
Supports building the library and the tests.
See CMakeLists.txt for notes on how it works.
I had to adjust 3 existing files in order to disable some configuration
that should be taken care of by cmake/automake anyway.
I also added jansson.def from a future jansson version,
to test cmake's support for .def files (which works fine).
