bb05e313eb use light-gray as default color in normal.mod for consistency
Defalut font color on PC console seems to be light-gray; this is
what user also gets in rescue prompt and what is defined as
GRUB_TERM_DEFAULT_NORMAL_COLOR. But normal.mod defaults to white.
This makes unpleasant visual effect as colors are changed after kernel
is booted.

Use the same color eveywhere for consistency and default to light-gray
as this is also what at least Linux kernel is using by default.

8f236c1419 Revamp hidden timeout handling
Add a new timeout_style environment variable and a corresponding
GRUB_TIMEOUT_STYLE configuration key for grub-mkconfig.  This
controls hidden-timeout handling more simply than the previous
arrangements, and pressing any hotkeys associated with menu entries
during the hidden timeout will now boot the corresponding menu entry
immediately.

GRUB_HIDDEN_TIMEOUT=<non-empty> + GRUB_TIMEOUT=<non-zero> now
generates a warning, and if it shows the menu it will do so as if
the second timeout were not present.  Other combinations are
translated into reasonable equivalents.

2d76b4d81e Eliminate variable length arrays in grub_vsnprintf_real.
A bit tricky because this function has to continue to work without
	heap for short strings. Fixing prealloc to 32 arguments is reasonable
	but make all stack references use 32-bit offset rather than 8-bit one.
	So split va_args preparsing to separate function and put the prealloc
	into the caller.

5c7206e45e Speed up test suite by avoiding fsync
Add grub_util_disable_fd_syncs call to turn grub_util_fd_sync calls into
no-ops, and use it in programs that copy files but do not need to take
special care to sync writes (grub-mknetdir, grub-rescue,
grub-mkstandalone).

On my laptop, this reduces partmap_test's runtime from 1236 seconds to
204 seconds.

c2b70d0981 Explicitly check for linking format to use for efiemu64 module
Similar to check for target linking format, also check for efiemu64
instead of hardcoding -melf_x86_64. This fixes compilation on *BSD
variants. We cannot easily reuse main target check because platforms
are different (main target is 32 bit and efiemu64 - 64 bit).

This commit adds EFIEMU64_LINK_FORMAT that contains detected
link option and is used in efiemu64.o linking instead of hardcoded
value.

4e42521d8c * grub-core/kern/x86_64/efi/callwrap.S: Fix stack alignment.
Previously we misaligned stack by 8 in startup.S and compensated
	for it in callwrap.S. According to ABI docs (EFI and sysv amd64)
	right behaviour is to align stack in startup.S and keep it aligned
	in callwrap.S. startup.S part was committed few commits before. This
	takes care of callwrap.S.

080603f0b0 Decrease stack usage in lexer.
We have only 92K of stack and using over 4K per frame is wasteful

	* grub-core/script/yylex.l (yyalloc), (yyfree), (yyrealloc): Declare
	as macros so that compiler would remove useless structure on stack.
	Better solution would be to fix flex not to put this structure on
	the stack but flex is external program.
