move Rust sources to top level, C sources into c_src

This moves the Rust sources out of rust_src/ and into the top level.
Running the bcachefs executable out of the development tree is now:

$ ./target/release/bcachefs command
or
$ cargo run --profile release -- command

instead of "./bcachefs command".

Building and installing is still:

$ make && make install

-/**
- * array_size - routine for safely deriving the size of a visible array.
- *
- * This provides a simple ARRAY_SIZE() macro, which (given a good compiler)
- * will also break compile if you try to use it on a pointer.
- *
- * This can ensure your code is robust to changes, without needing a gratuitous
- * macro or constant.
- *
- * Example:
- *	// Outputs "Initialized 32 values\n"
- *	#include <ccan/array_size/array_size.h>
- *	#include <stdlib.h>
- *	#include <stdio.h>
- *
- *	// We currently use 32 random values.
- *	static unsigned int vals[32];
- *
- *	int main(void)
- *	{
- *		unsigned int i;
- *		for (i = 0; i < ARRAY_SIZE(vals); i++)
- *			vals[i] = random();
- *		printf("Initialized %u values\n", i);
- *		return 0;
- *	}
