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).
