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.
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.
This patch arranges for symbols defined in .sdata and .sbss to be
reported by nm with 'g' and 's' flags, for coff targets that support
.sdata and .sbss.
The assembler changes regarding SEC_SMALL_DATA are really just
documentation. As far as I'm aware, this won't change any assembler
output.

It is only read in tc-m32r.c, so it might as well be static and const, and
that should help the compiler slightly.

* config/tc-m32r.c (mach_table): Make static and const.
various places either directly or indirectly set input_line_pointer to point at
a literal. Currently lots of places modify the string input_line_pointer
points at, so making it const isn't easy. Since most if not all of these
places assign to input_line_pointer to parse an expression it would probably be
best to add ways to generate and deal with expressions that doesn't involve
parsing strings, but for now adding some casts seems easiest.

- allowing true forward references (which will always assume the referenced
symbols have at the point of use) through the new .eqv pseudo-op and the
new == operator
- disallowing changing .equiv-generated equates (so that the protection this
provides is both forward and backward)
- snapshotting equates when their value gets changed so that previous uses
don't get affected by the new value.
- allowing expressions in places where absolute expressions (or register
names) are needed which were not completely resolvable at the point of
their definition but which are fully resolvable at the point of use
In addition it fixes PR/288.
