Do not require parsing in C, pre-split string in cmake and pass it as
command separated string array down to CPP, so that it can be interpolated
directly into a char *path[] array.

- Shuffle typedefs to avoid need for non-compliant forward declarations
- Fix non-compliant empty struct initializers
- Remove use of braced expressions
- Remove use of anonymous unions
- Avoid `void *` pointer arithmetic
- Fix several warnings reported by gcc -pedantic mode and clang 11 compilation

Instead of relying on json_object values internally, use custom types to
represent the different ucode value types which brings a number of
advantages compared to the previous approach:
- Due to the use of tagged pointers, small integer, string and bool
values can be stored directly in the pointer addresses, vastly
reducing required heap memory
- Ability to create circular data structures such as
`let o; o = { test: o };`
- Ability to register custom `tostring()` function through prototypes
- Initial mark/sweep GC implementation to tear down circular object
graphs on VM deinit
The change also paves the way for possible future extensions such as
constant variables and meta methods for custom ressource types.

* add cram based tests
* test under either valgrind or LLVM sanitizers
* add libFuzzer template

It doesn't work properly with out of tree builds etc.

Let's enforce additional automatic checks enforced by the compiler in
order to catch possible errors during compilation.

So it can be built out of the tree.

Probably using 3.0+ features anyway and should silence following
warning:
CMake Deprecation Warning at CMakeLists.txt:1 (cmake_minimum_required):
Compatibility with CMake < 2.8.12 will be removed from a future version of
CMake.
Update the VERSION argument <min> value or use a ...<max> suffix to tell
CMake that the project does not need compatibility with older versions.

Replace the former AST walking interpreter implementation with a single pass
bytecode compiler and a corresponding virtual machine.
The rewrite lays the groundwork for a couple of improvements with will be
subsequently implemented:
- Ability to precompile ucode sources into binary byte code
- Strippable debug information
- Reduced runtime memory usage
