ioport.c C++ conversion. Mostly internal changes, with no
intended differences from previous behavior. For drivers,
the main change is that input_port_read() no longer exists.
Instead, the port must be fetched from the appropriate device,
and then read() is called.
For member functions, this is actually simpler/cleaner:
value = ioport("tag")->read()
For legacy functions which have a driver_data state, it goes:
value = state->ioport("tag")->read()
For other legacy functions, they need to fetch the root device:
value = machine.root_device().ioport("tag")->read()
The other big change for drivers is that IPT_VBLANK is gone.
Instead, it has been replaced by a device line callback on the
screen device. There's a new macro PORT_VBLANK("tag") which
automatically points things to the right spot.
Here's a set of imperfect search & replace strings to convert
the input_port_read calls and fix up IPT_VBLANK:
input_port_read( *\( *)(machine\(\)) *, *([^)]+ *\))
ioport\1\3->read\(\)
input_port_read( *\( *)(.*machine[()]*) *, *([^)]+ *\))
\2\.root_device\(\)\.ioport\1\3->read\(\)
(state = .*driver_data[^}]+)space->machine\(\)\.root_device\(\)\.
\1state->
(state = .*driver_data[^}]+)device->machine\(\)\.root_device\(\)\.
\1state->
input_port_read_safe( *\( *)(machine\(\)) *, *([^,]+), *([^)]+\))
ioport\1\3->read_safe\(\4\)
IPT_VBLANK( *\))
IPT_CUSTOM\1 PORT_VBLANK("screen")
