Title: Code style


About: Source formatting

- C sources must be properly indented using two spaces per nesting level.
- Opening braces are put on the same line as there prelude statement and may be omitted consistently per block.
- Booleans from `stdbool` are preferred to binary integer values.
- Inside comparisons, the constant part should be on the right.
- Pointer declaration must be put adjacent to the declared identifier, not to the type.

In brief, a function should look like so:

> char *f(char *c) {
>   if (c % 2 == 0)
>     return 1;
>   else if (c == 1)
>     return 2;
>   else
>     return 3;
> }


About: Code structure

- Variables are declared at the top of a context.
- It is advised to declare variables on the stack instead of the heap when possible.
- The use of `assert` is encouraged.
- The use of `static` functions is encouraged. Such members must be declared prior to others.
- Imports should be thematically sorted, with the current spec file listed first, followed by external imports,
  then internal imports
