separate so you can for example have -harddisk1 as ID 6 and -harddisk 2 as ID 5. The HLE'd CD & HD have configuration switches to set the ID, real emulated hardware will specify the ID using it's own method. [smf]

Remove redundant machine items from address_space and device_t.
Neither machine nor m_machine are directly accessible anymore.
Instead a new getter machine() is available which returns a
machine reference. So:
space->machine->xxx ==> space->machine().xxx
device->machine->yyy ==> device->machine().yyy
Globally changed all running_machine pointers to running_machine
references. Any function/method that takes a running_machine takes
it as a required parameter (1 or 2 exceptions). Being consistent
here gets rid of a lot of odd &machine or *machine, but it does
mean a very large bulk change across the project.
Structs which have a running_machine * now have that variable
renamed to m_machine, and now have a shiny new machine() method
that works like the space and device methods above. Since most of
these are things that should eventually be devices anyway, consider
this a step in that direction.
98% of the update was done with regex searches. The changes are
architected such that the compiler will catch the remaining
errors:
// find things that use an embedded machine directly and replace
// with a machine() getter call
S: ->machine->
R: ->machine\(\)\.
// do the same if via a reference
S: \.machine->
R: \.machine\(\)\.
// convert function parameters to running_machine &
S: running_machine \*machine([^;])
R: running_machine \&machine\1
// replace machine-> with machine.
S: machine->
R: machine\.
// replace &machine() with machine()
S: \&([()->a-z0-9_]+machine\(\))
R: \1
// sanity check: look for this used as a cast
(running_machine &)
// and change to this:
*(running_machine *)

Subject: [patch] Add machine to some emu/machine init methods
Hi mamedev,
This patch widens some machine init interfaces to pass the machine
parameter, allowing more Machine global references to be eliminated.
Eventually most of these need to be converted to devices, but this
change reduces the deprecation surface in the meantime. I also
attached the script I used to do the initial changes to the drivers,
which handled about 90% of the cases without further editing.

Subject: [patch] More Machine->machine changes, add machine to irq
callbacks
Hi mamedev,
Here are two more patches to eliminate Machine globals. The first
patch was autogenerated by the attached fixup script. That script has
been updated to catch additional cases which it previously missed
(when Machine is the last parameter to a function or Machine is used
in an assignment). This makes ~50 more files deprecat.h free.
A sizable chunk (~20%) of the remaining uses of the Machine global in
the drivers are due to irq callbacks for sound and machine updates.
Typically such callbacks need to call cpunum_set_input_line, which
requires a machine parameter, so if the callbacks don't pass the
machine parameter, these routines have no choice but to reference the
global variable.
The second patch attempts to address most cases of this by adding the
machine parameter to the callback interfaces. This allows us to
remove #include "deprecat.h" from ~150 files, at the cost of having to
fix up hundreds of callbacks.
In total, these patches reduced the number of files with deprecat.h
from 783 to 575.

Fixed several memory leaks related to SCSI CD emulation.
