Added new module devcb, which can generically handle conversions between device

Browse Source 
read/write functions and various other types of functions. Introduced new
structures and macros to make this possible. 

To take advantage of this, a device must change its interface to replace and 
read/write callbacks with the new devcb_read/write structures. During device 
start time, the device then uses this new devcb module to resolve the information 
in the devcb_read/write structures into a more efficient form. When the device 
needs to call one of the callbacks, it uses the inline devcb_call_read/write 
functions.

Once a device has defined its callbacks as devcb_read/write structures, users
of the device must use the DEVCB_* macros to specify the type and information
about the handler to use:

   DEVCB_NULL = no handler
   DEVCB_HANDLER = a standard device read/write handler
   DEVCB_MEMORY_HANDLER = a memory address space read/write handler
   DEVCB_DEVICE_HANDLER = a device read/write handler for a different device
   DEVCB_INPUT_PORT = an input port

Converted the 8255PPI device to use this new structure, and updated all users
to use the DEVCB macros, removing some unnecessary trampoline functions along
the way.

These functions are used to adapt multiple read/write handler types

read_line_device_func: (device)
write_line_device_func: (device, data)
read8_device_func: (device, offset)
write8_device_func: (device, offset, data)
The adapted callback types supported are:
input port (port)
read_line_device_func: (device)
write_line_device_func: (device, data)
read8_device_func: (device, offset)
