* grub-core/video/i386/pc/vbe.c (grub_vbe_bios_get_flat_panel_info):
New function.
(grub_vbe_bios_get_ddc_capabilities): Likewise.
(grub_vbe_bios_read_edid): Likewise.
(grub_vbe_edid_checksum): Likewise.
(grub_vbe_get_preferred_mode): Likewise. Try EDID followed by the
Flat Panel extension, in line with the X.org VESA driver.
(grub_video_vbe_setup): When the mode is "auto", try to get the
preferred mode from VBE, and use the largest mode that is no larger
than the preferred mode (some BIOSes expose a preferred mode that is
not in their mode list!). If this fails, fall back to 640x480 as a
safe conservative choice.
* include/grub/i386/pc/vbe.h (struct grub_vbe_flat_panel_info): New
structure.
(struct grub_vbe_edid_info): Likewise.
(grub_vbe_bios_get_flat_panel_info): Add prototype.
(grub_vbe_bios_get_ddc_capabilities): Likewise.
(grub_vbe_bios_read_edid): Likewise.
* util/grub.d/00_header.in (GRUB_GFXMODE): Default to "auto". This
is more appropriate on a wider range of platforms than 640x480.
* grub-core/Makefile.core.def (vbeinfo): Removed.
(vbetest): Removed.
(videoinfo): New module.
* grub-core/commands/i386/pc/vbeinfo.c: Removed.

* grub-core/commands/videoinfo.c: New file.
* grub-core/commands/videotest.c (grub_cmd_videotest): Support mode
specification.
(grub_cmd_videotest) [GRUB_MACHINE_PCBIOS]: Load vbe.mod when invoked
as vbetest.
(GRUB_MOD_INIT) [GRUB_MACHINE_PCBIOS]: New command vbetest.
(GRUB_MOD_FINI) [GRUB_MACHINE_PCBIOS]: Unregister vbetest.
* grub-core/video/efi_gop.c (grub_video_gop_fill_mode_info): Fill
mode_number. New parameter mode. All users updated.
(grub_video_gop_iterate): New function.
(grub_video_efi_gop): New member iterate.
* grub-core/video/i386/pc/vbe.c (framebuffer): Removed leftover fields.
(grub_vbe_set_video_mode): Remove setting useless fields.
(vbe2videoinfo): New function.
(grub_video_vbe_iterate): Likewise.
(grub_video_vbe_setup): Use vbe2videoinfo.
(grub_video_vbe_print_adapter_specific_info): New function.
(grub_video_vbe_adapter): New fields iterate and
print_adapter_specific_info.
* include/grub/video.h (GRUB_VIDEO_MODE_*): Transform into enum.
All users updated.
(grub_video_mode_info): New field mode_number.
(grub_video_adapter): New fields iterate and
print_adapter_specific_info.
* grub-core/video/ieee1275.c (stdout_ihandle): New variable.
(have_setcolors): Likewise.
(grub_video_ieee1275_init): Fill stdout_ihandle and have_setcolors.
