grub_memset should zero out padding after data end. It is not clear
why it is needed at all - ZFS block is at least 512 bytes and power
of two, so it is always multiple of 16 bytes. This grub_memset
apparently never did anything.
In the past birth was always zero for holes. This feature started
to make use of birth for holes as well, so change code to test for
valid DVA address instead.
It can be called with NULL for third argument. grub_divmod32* for
now are called only from within wrappers, so skip check.

Some x86 systems might be capable of running a 64-bit Linux kernel but
only use a 32-bit EFI (e.g. Intel Bay Trail systems). It's useful for
grub-install to be able to recognise such systems, to set the default
x86 platform correctly.
To allow grub-install to know the size of the firmware rather than
just the size of the kernel, there is now an extra EFI sysfs file to
describe the underlying firmware. Read that if possible, otherwise
fall back to the kernel type as before.

Use the new thumb_get_instruction_word/thumb_set_instruction_word
helpers throughout.
Style cleanup (missing spaces).
Move Thumb MOVW/MOVT handlers into Thumb relocation section of file.
This restrict ARP handling to MAC and IP addresses but in practice we need
only this case anyway and other cases are very rar if exist at all. It makes
code much simpler and less error-prone.
_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.
LVM miscalculates bitmap size with small extent, so start with 16K as
for other RAID types.
Until version 2.02.103 LVM counts metadata segments twice when checking
available space, reduce segment count by one to account for this bug.
Write activity with LVM/RAID can happen after filesystem is unmounted.
In my testing modification time of loop files was 15 - 20 seconds
after unmount. So use time as close to unmount as possible as
reference instead.
argp_help attempts to translate empty string, which results in printing
meta information about translation, like in

Update gnulib/argp-help.c to the current version which fixes this
(commit b9bfe78424b871f5b92e5ee9e7d21ef951a6801d).

Update m4/extern-inline.m4 to current upstream gnulib version that
contains fix for this (commit b9bfe78424b871f5b92e5ee9e7d21ef951a6801d).

canonicalize_file_name clashed with gnulib function. Additionally
it was declared in 2 places: emu/misc.h and util/misc.h. Added
grub_ prefix and removed second declaration.
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.
