Introduce stdvga_dac_read_many() and stdvga_dac_write_many() for
writing multiple dac palette entries. Convert the stdvga_dac_read()
and stdvga_dac_write() low-level IO access functions in stdvgaio.c to
access just one color palette entry.

Don't use stdvga.h for function definitions of code in stdvgamodes.c
and stdvgaio.c. Move them to vgautil.h.

Move the inb(), insb(), etc. code from ioport.h to x86.h. Move the
PORT_* definitions to their appropriate hardware files.
