Thomas Bertschinger f5baaf48e3 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;
* }
