Function encoding_c::decoder_decode_to_utf8

#[no_mangle]
pub unsafe extern fn decoder_decode_to_utf8(decoder: *mut Decoder,
                                            src: *const u8,
                                            src_len: *mut usize,
                                            dst: *mut u8,
                                            dst_len: *mut usize,

Incrementally decode a byte stream into UTF-8 with malformed sequences replaced with the REPLACEMENT CHARACTER.

See the top-level FFI documentation for documentation for how the decoder_decode_* functions are mapped from Rust and the documentation for the Decoder struct for the semantics.

Undefined behavior

UB ensues if decoder is NULL, src and src_len don't designate a valid block of memory, dst and dst_len don't designate a valid block of memory or had_replacements is NULL.
