3be39f9792 More cleanup changes for the remapping. All machine-init functions now call mem_top_remap themselves, this is no longer inherited. machine_at_*_remap_init() functions removed. 
As an initial test, added remap to the NEAT - that works.

6b21c4c921 Big cleanup of the use of regular and const string pointers. Where possible, const is used to enfore R/O-ness of string arguments. 
Important change to the NVR code to "fix" the PS/1 and PS/2 systems, plus a cleanup.
All device tables now end with a NULL, not an empty string.
Configuration code now deals better with this.
Machine and Video lookup now return -1 if not found/available, and pc_init() will throw the user into Setup if that is the case.
If for some reason the configured memory size exceeds machine limit, it is now adjusted.

23fcf833b4 Change to not allow configured memory size to go over machine's limit (fixes #25.) 
Lots of cleanup changes all over to fix the constness of strings [again].
Some cleanups in config.c to remove old stuff.

30b6ac523e Made the Toshiba's T1000 ROM DOS configurable. 
Removed all xxx_get_dev() calls, and published the actual device_t's instead.
(first step to making all machines a device)

1cf45a9724 Applied relevant upstream commits. 
Converted AT NVR to be a device, so it gets auto-closed.
Added new machine_close() function which calls optional machine-custom close, updated machine table.
Small fixes here and there.
Re-wored the CDROM code to have a 'speeds' table instead of ugly hard-coding.
