2d1777b530 opcodes: microblaze: Fix bit masking bug 
There is currently a bug in the bit masking for the barrel shift
instructions because the bit mask is not including all of the
register bits which must be zero.  With this patch, the disassembler
can be sure that the 32-bit value is indeed a barrel shift instruction
and not a data value in memory.

This fix can be verified by assembling and disassembling the following:

	.text
	.long 0x65005f5f

With this patch, the bug is fixed, and the objdump will know that
0x65005f5f is not a barrel shift instruction.

bb0d05ff74 opcodes: microblaze: Add new bit-field instructions 
This patches adds new bsefi and bsifi instructions.
BSEFI- The instruction shall extract a bit field from a
register and place it right-adjusted in the destination register.
The other bits in the destination register shall be set to zero.
BSIFI- The instruction shall insert a right-adjusted bit field
from a register at another position in the destination register.
The rest of the bits in the destination register shall be unchanged.

Further documentation of these instructions can be found here:
https://docs.xilinx.com/v/u/en-US/ug984-vivado-microblaze-ref

With version 6 of the patch, no new relocation types are added as
this was unnecessary for adding the bsefi and bsifi instructions.

FIXED: Segfault caused by incorrect termination of microblaze_opcodes.

d87bef3a7b Update year range in copyright notice of binutils files 
The newer update-copyright.py fixes file encoding too, removing cr/lf
on binutils/bfdtest2.c and ld/testsuite/ld-cygwin/exe-export.exp, and
embedded cr in binutils/testsuite/binutils-all/ar.exp string match.

a2c5833233 Update year range in copyright notice of binutils files 
The result of running etc/update-copyright.py --this-year, fixing all
the files whose mode is changed by the script, plus a build with
--enable-maintainer-mode --enable-cgen-maint=yes, then checking
out */po/*.pot which we don't update frequently.

The copy of cgen was with commit d1dd5fcc38ead reverted as that commit
breaks building of bfp opcodes files.

52b8387412 opcodes: constify & scope microblaze opcodes 
This is exporting the variable "opcodes" as a large writable blob.
This is not a namespace friendly name, so add a "microblaze" prefix,
and then sprinkle const over its definition & use.

88c1242dc0 Move print_insn_XXX to an opcodes internal header 
With the changes done in previous patches, print_insn_XXX functions
don't have to be external visible out of opcodes, because both gdb
and objdump select disassemblers through a single interface.

This patch moves these print_insn_XXX declarations from
include/dis-asm.h to opcodes/disassemble.h, which is a new header
added by this patch.
