/** A simple refcounted data type representing an immutable byte sequence
 * from an unspecified origin.
 *
 * The purpose of the Bytes class is to keep the memory region that it holds
 * alive for as long as anyone holds a reference to the bytes.  When
 * the last reference count is dropped, the memory is released. Multiple
 * unrelated callers can use byte data in the Bytes object without coordinating
 * their activities, resting assured that the byte data will not change or
 * move while they hold a reference.
 *
 * A Bytes object can come from many different origins that may have
 * different procedures for freeing the memory region.  Examples are
 * memory from g_malloc(), from memory slices, from a GMappedFile or
 * memory from other allocators.
