c945ca75c3 Fix exit to EFI firmware 
The current code for EFI grub_exit() calls grub_efi_fini() before
returning to firmware. In the case of ARM, this leaves a timer
event running which could lead to a firmware crash. This patch
changes this so that grub_machine_fini() is called with a NORETURN
flag. This allows machine-specific shutdown to happen as well
as the shutdown done by grub_efi_fini().

5974d4ba65 hostfs: Drop unnecessary feature test macros 
_BSD_SOURCE was added to allow the use of DT_DIR, but that was removed
in e768b77068.  While adding
_DEFAULT_SOURCE as well works around problems with current glibc,
neither is in fact needed nowadays.

27d1a67f8a Fix canonicalize_file_name clash.

it was declared in 2 places: emu/misc.h and util/misc.h. Added
grub_ prefix and removed second declaration.

064360e667 Remove libgcc dependency. 
libgcc for boot environment isn't always present and compatible.
libgcc is often absent if endianness or bit-size at boot is different
from running OS.
libgcc may use optimised opcodes that aren't available on boot time.
So instead of relying on libgcc shipped with the compiler, supply
the functions in GRUB directly.
Tests are present to ensure that those replacement functions behave the
way compiler expects them to.

f034fab620 Supply signed division to fix ARM compilation. 
Previously we supplied only unsigned divisions on platforms that need software

Yet compiler may itself use a signed division. A typical example would be a

17328db3b3 grub-core/kern/arm/misc.S: fix unaligned grub_uint64_t local variable 
The unaligned local in __aeabi_uidivmod leads to a store to a 64bit
value at an address that is not divisible by 8 (in grub_divmod64).
The compiler most likely generates a STRD instruction to store it and
this causes an exception.

Fixes Savannah bug #43632.

This includes improvements done by Leif Lindholm.

004a2b1efd efi: check *path non-null before grub_strrchr 
The EFI version of grub_machine_get_bootlocation crops the boot image
name back to the last / in order to get a directory path. However, it
does not check that *name is actually set before calling grub_strrchr
to do this, and neither does grub_strrchr before dereferencing a NULL
pointer.

Parent function, grub_set_prefix_and_root, does check the pointer
before using.

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.

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.

	entitled to assume that stack alignment without checking.

resolves the problem, while keeping the new, cleaner transition_space
