pxe: resolve names via DNS from protected-mode code
Syslinux used to call __intcall() for calling routines of the old
COMBOOT API to resolve names via DNS (INT 22h, AX=0x0010) that seemed
pointless, since INT 22h, AX=0x0010 does call the protected-mode
function pm_pxe_resolv_dns() when calling INT 22h, AX=0x0010. So, for
resolving names via DNS we must call pxe_dns_resolv() (a protected-mode
function) instead for now.
