FFI: canonicalize array, data pointer for primitives

[myrrc]

• Add canonicalize function for vx_array.
• Add data_ptr functions for canonicalized primitive and bool arrays.
• Add sink abort method which doesn't write file footer and leaves file invalid. Semantics here is we want to abort the sink in C++ destructor - if user hasn't called Finalize(), file will not be written correctly.
• Expose Rust's error code to FFI.
