a simple 32 bits protected mode interface to some VESA functions. This
protected mode interface is interesting because it's quicker than the
raw int 10h interface.
Unfortunatly, begining with VBE 3.0, the 0x4f0a function is optional,
and some video cards don't implement it (3dfx, intel 845/855/865...).
This protected mode interface is then only used in vbeSetWindow and
vbeSetDisplayStart :
- vbeSetWindow already implement an alternative methode if protected
mode interface is not available.
- vbeSetDisplayStart also contain an alternative implementation, but
this one is disabled with a #if 0. I don't exactly know why because
it works well !
So currently, cards which don't have the 0x4f0a function are not
supported. This patch correct this.
- vbeGetProtModeInfo failure is not fatal.
- vbeSetDisplayStart has it's alternative implementation reenabled.
it's used only with cards which don't have the 0x4f0a function
so this won't make any difference for cards which were already
working.
This patch also make the failure of vbeGetModeInfo not fatal. The
VBE 3.0 standard state that GetModeInfo can fail with some mode
which are listed as supported if the mode can't be used in the
current situation (not enough video memory for example). So a
failure of vbeGetModeInfo don't mean that other modes won't work
and should really not be fatal.

doesn't make sense anyway, because freopen will always return the same FILE * structure that it got in parameter. patch by Mikulas Patocka <mikulas@artax.karlin.mff.cuni.cz>

- VESA detection by sys/io.h header
- workaround a missing define on libc5
