[v0.13.0]

Added

• [#247] Add ReadVolatile and
  WriteVolatile traits which are equivalents of Read/Write with volatile
  access semantics.

Changed

• [#247] Deprecate
  Bytes::{read_from, read_exact_from, write_to, write_all_to}. Instead use
  ReadVolatile/WriteVolatile, which do not incur the performance penalty
  of copying to hypervisor memory due to Read/Write being incompatible
  with volatile semantics (see also #217).
