62daa27056 util: Detect more I/O errors
Many of GRUB's utilities don't check anywhere near all the possible
write errors.  For example, if grub-install runs out of space when
copying a file, it won't notice.  There were missing checks for the
return values of write, fflush, fsync, and close (or the equivalents on
other OSes), all of which must be checked.

I tried to be consistent with the existing logging practices of the
various hostdisk implementations, but they weren't entirely consistent
to start with so I used my judgement.  The result at least looks
reasonable on GNU/Linux when I provoke a write error:

  Installing for x86_64-efi platform.
  grub-install: error: cannot copy `/usr/lib/grub/x86_64-efi-signed/grubx64.efi.signed' to `/boot/efi/EFI/debian/grubx64.efi': No space left on device.

There are more missing checks in other utilities, but this should fix
the most critical ones.

Fixes Debian bug #922741.

69e0a67bfb sparc64: Add blocklist GPT support for SPARC
Add block-list GPT support for SPARC.  The OBP "load" and "boot" methods
are partition aware and neither command can see the partition table. Also
neither command can address the entire physical disk. When the install
happens, grub generates the block-list entries based on the beginning of the
physical disk, not the beginning of the partition. This patch fixes the
block-list entries so they match what OBP expects during boot for a GPT disk.

T5 and above now supports GPT as well as VTOC.

This patch has been tested on T5-2 and newer SPARC systems.

f585c90505 fix partition module names when /boot is on diskfilter
/usr/local/grub2/sbin/grub-install: info: grub-mkimage --directory '/usr/local/grub2/lib/grub/i386-pc' --prefix '(mduuid/e6d1dcf06cea72140bafae74a8677f36)/grub' --output '/boot/grub/i386-pc/core.img' --format 'i386-pc' --compression 'auto'  'ext2' 'msdos' 'msdos' 'diskfilter' 'mdraid1x' 'biosdisk'
.
/usr/local/grub2/sbin/grub-install: error: cannot open `/usr/local/grub2/lib/grub/i386-pc/msdos.mod': No such file or directory.

Introduce common helper for both diskfilter and non-diskfilter case that
converts partition map names into module names.

69ca97c820 fix using grub device name as install device
Shell version of grub-install called grub-setup which resolved
install device name and called main setup routine. C version of
grub-install calls main setup routine directly, which leads
to the error:

grub2-install: info: grub-bios-setup  --verbose  --force  --skip-fs-probe --directory='/boot/grub2/i386-pc' --device-map='/boot/grub2/device.map' '(hd2)'.
grub2-install: info: reading /boot/grub2/i386-pc/boot.img.
grub2-install: info: reading /boot/grub2/i386-pc/core.img.
grub2-install: info: root is `(null)', dest is `(hd2)'.
grub2-install: info: Opening dest.
grub2-install: info: drive = -1.
grub2-install: error: disk `(hd2)' not found.

Move resolving of destination device name into main setup routine
so it is done consistently in both cases.
