47e67d809c Remove pragmas related to -Wunreachable-code
-Wunreachable-code has been a no-op since GCC 4.5; GRUB hasn't been
compiled with it since 2012; and GCC 6 produces "error:
'-Wunreachable-code' is not an option that controls warnings" for these.

Fixes Debian bug #812047.

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)

aafd205c92 xfs: fix possible inode corruption in directory scan
grub_xfs_iterate_dir did not restore first character after inline
name when match was found. Dependning on XFS format this character
could be inode number and we could return to the same node later in
find_file if processing cycled symlinks.

bd60f5a207 rescue_parser: restructure code to avoid Coverity false positive
If line contains single word, line and argv[0] are aliases, so
no NULL dereference is possible, but Coverity does not know it.
Change code to avoid ambiguity and also remove redundant call to
grub_strchr.

4d5d7be005 Send a user class identifier in bootp requests
It's helpful to determine that a request was sent by grub in order to permit
the server to provide different information at different stages of the boot
process. Send GRUB2 as a type 77 DHCP option when sending bootp packets in
order to make this possible.

297e11980b Allow passing of trusted keys via variables

called "trust_var". This takes the contents of a variable (in ascii-encoded
hex) and interprets it as a gpg public key.

73746f0367 Fix hex representation of binary variable contents
The getenv code was mishandling the conversion of binary to hex. Grub's
sprintf() doesn't seem to support the full set of format conversions, so
fix this in the nasty way.

7eb27a49e9 arm-efi: Reduce timer event frequency by 10
Timer event to keep grub msec counter was running at 1000HZ. This was too
fast for UEFI timer driver and resulted in a 10x slowdown in grub time
versus wallclock. Reduce the timer event frequency and increase tick
increment accordingly to keep better time.
