* Represents an immutable reference counted block of memory. * This is basically the internal glib GBuffer structure exposed, renamed, and with some additional capabilities. * The GBytes name comes from python3's immutable 'bytes' type * GBytes can be safely used as keys in hash tables, and have functions for doing so: g_bytes_hash, g_bytes_equal * GByteArray is a mutable form of GBytes, and vice versa. There are functions for converting from one to the other efficiently: g_bytes_unref_to_array() and g_byte_array_free_to_bytes() * Adds g_byte_array_new_take() to support above functions https://bugzilla.gnome.org/show_bug.cgi?id=663291
