43dbf83aa2 Ensure that grub_reboot doesn't return on emu. 
Use grub_fatal if longjmp fails.

grub_reboot is marked as noreturn so return would cause
a crash.

269a522c7d hostdisk: fix device detection 
Condition was apparently reversed so GRUB assumed all devices were
files. This later made it skip BLKFLSBUF ioctl on Linux which caused
various page cache coherency issues. Observed were

- failure to validate blocklist install (read content did not match
  just written)

- failure to detect Linux MD on disk after online hot addition
  (GRUB got stale superblock)

Closes: 46691

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. 
canonicalize_file_name clashed with gnulib function. Additionally

grub_ prefix and removed second declaration.

cd46aa6cef Rewrite grub-install, grub-mkrescue, grub-mkstandalone and grub-mknetdir 
the function of these files exceeds what can be sanely handled in shell
	in posix-comaptible way. Also writing it in C extends the functionality
	to non-UNIX-like OS and minimal environments.
