Olivier Galibert 639c9b85fc memory: Allow simplified versions of handlers [O. Galibert] 
A standard memory handler has as a prototype (where uX = u8, u16, u32 or u64):
  uX device::read(address_space &space, offs_t offset, uX mem_mask);
  void device::write(address_space &space, offs_t offset, uX data, uX mem_mask);

We now allow simplified versions which are:
  uX device::read(offs_t offset, uX mem_mask);
  void device::write(offs_t offset, uX data, uX mem_mask);

  uX device::read(offs_t offset);
  void device::write(offs_t offset, uX data);

  uX device::read();
  void device::write(uX data);

Use them at will.  Also consider
(DECLARE_)(READ|WRITE)(8|16|32|64)_MEMBER on the way out, use the
explicit prototypes.

Same for lambdas in the memory map, the parameters are now optional
following the same combinations.
