The current documentation for the special environment variable
"default" is confusing and unclear. This patch attempts to clean it
up.
In particular, the current documentation refers to the "number or
title", but then in the example it gives, the menu entries and
submenus all have numbers *in* their title; furthermore, there is no
example given about how to choose the number, or any indication about
whether counting is zero-indexed or 1-indexed.
Having a cleaner example and presenting all variants (numeric, title,
and id) should make it clearer to the user.

Unified Extensible Firmware Interface Specification, Version 2.6,
section 2.3.4, x64 Platforms, boot services, says among others:
The stack must be 16-byte aligned. So, do it. Otherwise OS may
boot only by chance as it happens right now.

According to EABI only STT_FUNC has convention of lowest bit indicating
execution mode. R_THM_{JUMP,CALL}* relocations are assumed to be pointing
to thumb mode unless they use STT_FUNC.
We need -static as otherwise linker will set interpreter field and ld.so
is not available on our initrd's.
Strip all sections we don't need on binary tests.
If ascent is bigger than height - 2, then we draw over character box but then
to clear cursor we only draw over character box. So trim ascent if necessarry.
We don't use lgcc_s but missing lgcc_s or another library cause test to fail.
So use -nostdlib.
We need to use -Werror to avoid warning-generated case to be accepted.
Clang uses -nopie rather than -no-pie. Check both and use whichever one works.
Additionally android clang passes -pie to the linker even though it doesn't
define __PIE__. So if compilation without no-pie logic fails add -nopie/-no-pie
even if __PIE__ is not defined.
clang 3.8 and later doesn't support -mllvm -use-arm-movt=0
whereas older clang doesn't know -mno-movt. So use
-mno-movt whenever possible and fallback to mllvm variant.
proot creates hidden files with .proot prefix and name
derived from real file name. So decrease file name length
and path depth. For some reason depth 85 also results in
undeleteable directory, so use 84 instead of 85.
o Add some comments.
o Change image buffer type to (const void *).
o Add new macro VERITY_CMDLINE_LENGTH.

These entries have placeholder for device name and so are useless for our
purpose. grub failed with something like
grub-install: error: failed to get canonical path of `systemd-1'.
When we see autofs entry, record it (to keep parent-child relationship) but
continue to look for real mount. If it is found, we process it as usual. If
only autofs entry exists, attempt to trigger mount by opening mount point
and retry. Mount point itself is then kept open to avoid timeout.
Recent systemd is by default using automount for /boot/efi so this should
become more popular problem on EFI systems.

glibc 2.25 still includes sys/sysmacros.h in sys/types.h but also emits
deprecation warning. So test for sys/types.h succeeds in configure but later
compilation fails because we use -Werror by default.
While this is fixed in current autoconf GIT, we really cannot force everyone
to use bleeding edge (that is not even released right now). So run test under
-Werror as well to force proper detection.
This should have no impact on autoconf 2.70+ as AC_HEADER_MAJOR in this version
simply checks for header existence.
