fs/xfs: Add large extent counters incompat feature support
XFS introduced 64-bit extent counters for inodes via a series of
upstream commits and the feature was marked as stable in v6.5 via
commit 61d7e8274cd8 (xfs: drop EXPERIMENTAL tag for large extent
counts).
Further, xfsprogs release v6.5.0 switched this feature on by default
in mkfs.xfs via commit e5b18d7d1d96 (mkfs: enable large extent counts
by default).
Filesystems formatted with large extent count support, nrext64=1, are
thus currently not recognizable by GRUB, since this is an incompat
feature. Add the required support so that those filesystems and inodes
with large extent counters can be read by GRUB.

gpt: Add compile time asserts for guid and gpt_partentry sizes
With new alignment specification it's easy to screw up. Fortunately if it
happens the size will be bigger than intended. Compile time assert will catch
this.

On ia64 alignment requirements are strict. When we pass a pointer to
UUID it needs to be at least 4-byte aligned or EFI will crash.
On the other hand in device path there is no padding for UUID, so we
need 2 types in one formor another. Make 4-byte aligned and unaligned types
The code is structured in a way to accept unaligned inputs
in most cases and supply 4-byte aligned outputs.
Efiemu case is a bit ugly because there inputs and outputs are
reversed and so we need careful casts to account for this
inversion.

gpt_partition: Mark grub_gpt_partentry as having natural alignment
gpt_partition contains grub_guid. We need to decide whether the whole
structure is unaligned and then we need to use packed_guid. But we never
have unaligned part entries as we read them in an aligned buffer from disk.
Hence just make it all aligned.

efi: Deduplicate configuration table search function
We do table search in many places doing exactly the same algorithm.
The only minor variance in users is which table is used if several entries
are present. As specification mandates uniqueness and even if it ever isn't,
first entry is good enough, unify this code and always use the first entry.

util/grub-mount: Check file path sanity
The function argp_parser() in util/grub-mount.c lacks a check on the
sanity of the file path when parsing parameters. This results in
a segmentation fault if a partition is mounted to a non-existent path.
