Add code to read and write bt463-style ramdacs; pick ramdac interface
...
functions based on type returned from tga_getconf().
Adapt to change in ramdac interface.
Fix race condition in tga_sched_update().
Make tga_sched_update() work before interrupts are enabled.

Added basic TGA2 support to the TGA driver. Abstracted the RAMDAC

currently support.

fix problems in many d_mmap routines:
...
- returned EOPNOTSUPP rather than -1.
- no check for negative offset.
many of these fix potential security problems in these drivers.
XXX XXX XXX
the d_mmap cdev routine should be changed to have a prototype like:
paddr_t (*d_mmap) __P((dev_t, off_t, int));
by someone!

Since the RAMDAC drivers use the !=0-ness of fields for diagnostic

purposes, we have to zero-initialize the tga_devconfig structure.

Simple screen attribute handling for wscons.
...
The graphics device driver passes a "default attribute" for normal text
output to the wscons framework. If the emulation module needs more
attributes (for different "renditions") it can allocate them via a
callback.
For now, only the "sun" emulation makes use of it.

The "mi" TGA driver. It's still not of much use on anything but alpha
