Debian and all its derivatives ship a broken Lua 5.4 that is missing some symbols.
To work around broken distros and make development and distribution easier use the wrap by default and add an option to use the system version.
defining anything that isn't a specific set of architectures x86 is just wrong.
It should at least be called something non identifying like "native"
Lite-XL already builds for FreeBSD so add it to the platform detection
Lua provides no offical pkg-config configuration but some systems still have it.
Instead of assuming the System has none, try using the C compiler to find it.
This may give us an incorrect lua version, but its better than nothing at all.
* Update meson.build
- add logic to loop over more lua names (in the future more names might be discovered)
- disable warnings and errors on dependencies
* adding missing includes and checks, correct data types, pointer mess […]
- various functions from string.h were used but never defined
- logic was done across multiple different data types with different signedness, got all of them up to snuff
- give 0 sized array size of 1 (array of size 0 is illegal, but rewriting the code is out of the scope of this commit)
- add preprocessor that marks possibly unused argument as such (does not mean they will get optimized out or anything)
- correctly initialize structs with all data needed
All these were found by generating the project using `meson -Dwarning_level=3 -Dwerror=true`
* remove undefined behavior, correct data types
* Comment manual bit manipulation to be investigated
* check for more edge cases, replace multiple cleanups with goto
* remove system specific includes
