- Removed device_timer, device_timer_id, et al in favor of direct callback members. (#9788)
Primarily, this removes device_t::device_timer, device_t::timer_set,
device_t::synchronize, device_t::timer_expired, and device_timer_id.
Use of device_timer often resulted in unnecessary trampolining in
addition to switch/case overhead on a driver/device level, and
additional logic to manage delegated vs. ID-based timers on a core
level. In the worst cases, devices were performing a switch/case with
only one valid case.
device_scheduler::timer_set is marked deprecated as the only remaining
direct uses are via the Lua engine and a few drivers that need
refactoring anyway. The remaining uses occur via
device_scheduler::synchronize.
As a middle ground between the extremely short timer_alloc() and the
extremely long
machine().scheduler().timer_alloc(timer_expired_delegate(FUNC(widget_device::contoso_tick), this)),
a helper function in device_t has been added which can be invoked with
the following syntax:
timer_alloc(FUNC(widget_device::contoso_tick), this)
