Not all instances need to be initialized as often they are copied or
written to, but doing all ensures no surprises.
Move the ^= operator to MD5Hash while we're at it.
The fmt code pushes a pragma option, and later pops is. The intrinsics code
interacts with it via the __OPTIMIZE__ macro. This has been set by the pragma
option push, but not unset/reset to the original with the pop.
Since the pragma is only used for the GCC compiler (not Clang, not MSVC, not
ICC) and in debug mode, just remove the whole pragma handling for it.
This means we have RTL support again with ICU 58+. It makes use of:
- ICU for bidi-itemization
- ICU for script-itemization
- OpenTTD for style-itemization
- harfbuzz for shaping
Also the memory allocation triggering the limit was never freed.
And if the exception was thrown in a constructor using placement new, the pre-allocated memory was not freed either.
Due to 47a99bb the order of elements in the garbage collection chain has
changed causing the class to be finalised before the instances of that class.
Since the instance's array of member values depends on the size of the values
in the class, the class finalisation resetting that size to 0 causes not all
finalisations to run, which subsequently causes a heap use after free. So,
just set the SQObjectPtrs to 'null' during the finalisation of the SQClass
so the SQInstance can release all instance variables during its finalisation.
CMake works on all our supported platforms, like MSVC, Mingw, GCC,
Clang, and many more. It allows for a single way of doing things,
so no longer we need shell scripts and vbs scripts to work on all
our supported platforms.
Additionally, CMake allows to generate project files for like MSVC,
KDevelop, etc.
This heavily reduces the lines of code we need to support multiple
platforms from a project perspective.
Addtiionally, this heavily improves our detection of libraries, etc.
This can avoid out-of-memory situations due to single scripts using up the entire address space.
Instead, scripts that go above the maximum are killed.
The maximum is default 1 GB per script, but can be configured by a setting.
