ec550fa07b Fixed pick_best_mode in both d3d and ddraw cases to manually extract 
refresh information from the device's inline_config, since this is
done before the screen devices are start. Fixes 01491: switchres 
causes Exception at EIP=009413BF: ACCESS VIOLATION.

Also, fixed render_target_get_minimum_size() to return nominal values
if no screens are found.

7a0931f08d Fix chicken and egg problem with device_start callbacks. 
Added DEVINFO_INT_TOKEN_BYTES, which is queried before device
startup. It should return the size of the structure that will
be hung off of device->token. It must not return 0.

Changed the core device interface to allocate and zero a block
of memory the size of DEVINFO_INT_TOKEN_BYTES before calling
device_start. The pointer to this memory is already attached
to device->token at the time device_start is called.

The primary motivation for this is to allow the device_start
function to make internal calls and pass the device_config *
around as if the object were fully constructed. Since the token
is used to indicate whether or not a device is live, this makes
the device "live" at the time device_start is called rather
than after it completes.

e7508371ed Fix for screenless (and deviceless) systems - this fix assumes that it is 
illegal to pass a NULL listhead to device_list_first() and that the assert there
should stand.  Please review and correct if appropriate.

7fb7afb780 - Changes exidy440_sound_command back to "UINT8." Since it's used by both 8-bit and 16-bit system, 
the automatic allocation is not worth it if you need an ugly UINT16 ** cast.
- Removed deprecat.h from some of the files here

e4a07ea688 Implements scanline based timer devices. 
Converted Centipede, as an example.

To define a scanline timer, use something like this:

MDRV_TIMER_ADD("32V", SCANLINE, generate_interrupt)
MDRV_TIMER_SCANLINE("main", 0, 16)

The first number is the first scanline the timer will fire on, the 2nd number is the increment.
So in this case, the timer will fire on 0, 16, 32, ..., 224, 240, then wrap around
because the screen is defined as 256 lines high.
The current scanline is passed to the callback in its 'param' argument

13f82f7331 Fix: 01496: all segae.c drivers: Crashing with Access Violation 
This driver is creating bitmaps in DRIVER_INIT, which is not the best practice, and in fact, it broke as machine->primary_bitmap is not initalized yet.

2f37f76c57 Fix: 01498: otwalls: Hangs before the game starts. 
Caused by RansAckeR input port "simplifications."  I put it in quotes, because I think it makes the input port definitions completely unreadable.

c0ca716e62 Added skeletion device interface for timers. Just wanted to get feedback. 
- Where applicable, added a parallel set of timer functions that take a device_config instead of emu_timer:
	void timer_device_adjust_oneshot(const device_config *timer, attotime duration, INT32 param);
	void timer_device_adjust_periodic(const device_config *timer, attotime duration, INT32 param, attotime period);
	void timer_device_reset(const device_config *timer, attotime duration);
	int timer_device_enable(const device_config *timer, int enable);
	int timer_device_enabled(const device_config *timer);
	int timer_device_get_param(const device_config *timer);
	void *timer_device_get_param_ptr(const device_config *timer);
	attotime timer_device_timeelapsed(const device_config *timer);
	attotime timer_device_timeleft(const device_config *timer);
	attotime timer_device_starttime(const device_config *timer);
	attotime timer_device_firetime(const device_config *timer);

- Added MACHINE_CONFIG macros:
	MDRV_TIMER_ADD(_tag, _type, _callback)	/* type can only be PERIODIC right now (can scanline based later, or even NE555) */
	MDRV_TIMER_REMOVE(_tag)
	MDRV_TIMER_MODIFY(_tag)
	MDRV_TIMER_TYPE(_type)
	MDRV_TIMER_CALLBACK(_callback) 
	MDRV_TIMER_DURATION(_duration)
	MDRV_TIMER_PERIOD(_period)
	MDRV_TIMER_PARAM(_param)
	MDRV_TIMER_PTR(_ptr)

- Modified Space Encounters to create two timers and use those:

	MDRV_TIMER_ADD("STROBE_ON", PERIODIC, spcenctr_strobe_timer_callback)
	MDRV_TIMER_PARAM(TRUE)	/* indicates strobe ON */
	MDRV_TIMER_PERIOD(UINT64_ATTOTIME_IN_HZ(SPCENCTR_STROBE_FREQ))

	MDRV_TIMER_ADD("STROBE_OFF", PERIODIC, spcenctr_strobe_timer_callback)
	MDRV_TIMER_PARAM(FALSE)	/* indicates strobe OFF */
	MDRV_TIMER_DURATION(UINT64_ATTOTIME_IN_HZ(SPCENCTR_STROBE_FREQ * 100 / SPCENCTR_DUTY_CYCLE))
	MDRV_TIMER_PERIOD(UINT64_ATTOTIME_IN_HZ(SPCENCTR_STROBE_FREQ))

Subject: small fix to cpu.mak

Attached please find a small patch to include M68000 CPU only when you're 
compiling a build with the M68K. this is needed to e.g. compile tiny 
builds .
