* New upstream release, including:
  - PIE support (Closes: #346409).
  - C++ improvements, including static_cast<> et al, namespace imports,
    and bug fixes in printing virtual base classes.
  - Multi-program debugging.  One GDB can now debug multiple programs
    at the same time.
  - Python scripting improvements, including gdb.parse_and_eval.
  - Updated MIPS Linux signal frame layout (Closes: #570875).
  - No internal error stepping over _dl_debug_state (Closes: #569551).
* Update to Standards-Version: 3.8.4 (no changes required).
* Include more relevant (and smaller) docs in the gdbserver package
  (Closes: #571132).
* Do not duplicate documentation in gdb64, gdb-source, and libgdb-dev.
* Fix crash when switching into TUI mode (Closes: #568489).
