3c42272105 docs: Use @ref instead of @xref
The @xref command is meant to be used at the beginning of a sentence
because its expansion creates a "See " prefix on all output formats, and
on older makeinfo versions is strict about enforcing a "." or "," after
the command. The @ref command has no such restriction and is just the
link, which allows more control over output. This also fixes an issue
where there was a repeated "see" in the output.

14c95e57fd kern/misc: Make grub_vsnprintf() C99/POSIX conformant
To comply with C99 and POSIX standards, snprintf() should return the
number of bytes that would be written to the string (excluding the
terminating NUL byte) if the buffer size was big enough. Before this
change, the return value was the minimum of the standard return and the
length of the buffer. Rarely is the return value of grub_snprintf() or
grub_vsnprintf() used with current code, and the few places where it is
used do not need to be changed.

1de5832699 commands/videoinfo: Prevent crash when run while video driver already active
The videoinfo command will initialize all non-active video adapters. Video
drivers tend to zero out the global framebuffer object on initialization.
This is not a problem when there is no active video adapter. However, when
there is, then outputting to the video adapter will cause a crash because
methods in the framebuffer object are reinitialized. For example, this
command sequence will cause a crash.

  terminal_output --append gfxterm; videoinfo

When running in a QEMU headless with GRUB built for the x86_64-efi target,
the first command initializes the Bochs video adapter, which, among
other things, sets the set_page() member function. Then when videoinfo is
run, all non-Bochs video adapters will be initialized, each one wiping
the framebuffer and thus setting set_page to NULL. Soon after the videoinfo
command finishes there will be a call to grub_refresh(), which will
ultimately call the framebuffer's set_page which will be NULL and cause
a crash when called.

6425c12cd7 efi: Fallback to legacy mode if shim is loaded on x86 archs
The LoadImage() provided by the shim does not consult MOK when loading
an image. So, simply signature verification fails when it should not.
This means we cannot use Linux EFI stub to start the kernel when the
shim is loaded. We have to fallback to legacy mode on x86 architectures.
This is not possible on other architectures due to lack of legacy mode.

This is workaround which should disappear when the shim provides
LoadImage() which looks up MOK during signature verification.

On the occasion align constants in include/grub/efi/sb.h.

16b09cd056 loader/linux: Only emit newc directory once
When creating at runtime a newc initrd via arguments to initrd with "newc:"
prefixes, only emit a directory path record once. The original code
intended to do that by bailing out of emitting the record when the record
to be created matches an existing record. However, this does not happen
because grub_memcmp() is improperly checked.

Generating duplicate newc directory records does not cause any problems
because the Linux unpacker will skip it once it sees the directory already
exists. This fix saves a little processing and makes the generated newc
cpio archive a little smaller.

17d6ac1a7d emu: Add SDL2 support
So all we did with the surface in SDL1 was split into window,
surface, renderer and texture. Instead of drawing into the
surface and then flipping, you build your pixels, then update
a texture and then copy the texture to the renderer.

Here we use an empty RGB surface to hold our pixels, which enables
us to keep most of the code the same. The SDL1 code has been adjusted
to refer to "surface" instead of "window" when trying to access the
properties of the surface.

This approaches the configuration by adding a new --enable-grub-emu-sdl2
argument. If set to yes, or auto detected, it disables SDL1 support
automatically.

This duplicates the sdl module block in Makefile.core.def which may
be something to be aware of, but we also don't want to build separate
module.
