stand/multiboot: adjust the protocol between loader and kernel There's a currently ad-hoc protocol to hand off the FreeBSD kernel payload between the loader and the kernel itself when Xen is in the middle of the picture. Such protocol wasn't very resilient to changes to the loader itself, because it relied on moving metadata around to package it using a certain layout. This has proven to be fragile, so replace it with a more robust version. The new protocol requires using a xen_header structure that will be used to pass data between the FreeBSD loader and the FreeBSD kernel when booting in dom0 mode. At the moment the only data conveyed is the offset of the start of the module metadata relative to the start of the module itself. This is a slightly disruptive change since it also requires a change to the kernel which is contained in this patch. In order to update with this change the kernel must be updated before updating the loader, as described in the handbook. Note this is only required when booting a FreeBSD/Xen dom0. This change doesn't affect the normal FreeBSD boot protocol. This fixes booting FreeBSD/Xen in dom0 mode after 3630506b9daec9167a89bc4525638ea45a00769e.

Add VT driver for VBE framebuffer device Implement vt_vbefb to support Vesa Bios Extensions (VBE) framebuffer with VT. vt_vbefb is built based on vt_efifb and is assuming similar data for initialization, use MODINFOMD_VBE_FB to identify the structure vbe_fb in kernel metadata. struct vbe_fb, is populated by boot loader, and is passed to kernel via metadata payload.
