587d1e78c9 mkimage: Pass layout to mkimage_generate_elfXX rather than some fields. 
This allows easier extension of this function without having too long of
arguments list.

1c4dc293df x86-64: Treat R_X86_64_PLT32 as R_X86_64_PC32 
Starting from binutils commit bd7ab16b4537788ad53521c45469a1bdae84ad4a:

https://sourceware.org/git/?p=binutils-gdb.git;a=commit;h=bd7ab16b4537788ad53521c45469a1bdae84ad4a

x86-64 assembler generates R_X86_64_PLT32, instead of R_X86_64_PC32, for
32-bit PC-relative branches.  Grub2 should treat R_X86_64_PLT32 as
R_X86_64_PC32.

4bd4a88725 i386, x86_64, ppc: fix switch fallthrough cases with GCC7 
In util/getroot and efidisk slightly modify exitsing comment to mostly
retain it but still make GCC7 compliant with respect to fall through
annotation.

In grub-core/lib/xzembed/xz_dec_lzma2.c it adds same comments as
upstream.

In grub-core/tests/setjmp_tets.c declare functions as "noreturn" to
suppress GCC7 warning.

In grub-core/gnulib/regexec.c use new __attribute__, because existing
annotation is not recognized by GCC7 parser (which requires that comment
immediately precedes case statement).

Otherwise add FALLTHROUGH comment.

42e24b6006 Fix thumb compilation with clang. 
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.

36212460d3 mkimage.c: Split into separate files. 
util/grub-mkimagexx.c is included in a special way into mkimage.c.
Interoperation between defines makes this very tricky. Instead
just have a clean interface and compile util/grub-mkimage*.c separately
from mkimage.c

1018e91dce mkimage: zero fill alignment space 
This did not cause real problem but is good for reproducible builds. I hit
it with recent bootinfoscript that displays embedded config; I was puzzled
by random garbage at the end.

Prezero memory buffer used to assemble core.img. This makes individual
memset redundant. Also ensure buffer is filled with zeroes in several other
places.

Also remove redundant zeroing code where we fill in the whole memory block
anyway.
