fix: using the linker for generating a .o file is a feature for only GNU ld.

those to object files.

fix: log macros were using GNU extensions without them needing them.
...
We can optionally add `,` utilising the `__VA_OPT__` macro. However,
this lead to the next problem, which is that an empty vardiac parameter
is a C23 extension. This was solved by dropping the string parameter,
making it be part of the vardiac parameters.

start writing code for decompressing chunk data.

I still haven't much of an idea where I'll take this, but it's a start.
I know it is needed for block filtering and such, I still need to find a
way how I'll actually implement it.

rework error.h, to decrease impact on binary size.
...
We were statically creating a new string per log message, so re-using
the same message would cause duplicate byte sizes.
Now, all prefixes / suffixes are only defined once, the file name is
defined once per file, the line number should be defined once per unique
line.
This just saves some memory in the final binary, allowing things to be
optimised a little better.

fix: violating strict aliasing rules in most areas in the new code.
...
Yes, I am aware there are plenty of violations in `conf.c`, but I'll
likely fix/rewrite those when I will use it. Since there are some other
changes I think I'll want to make.
