Patch to remove the use of the c++ keyword class in binutil sources.

[Martin Thuresson]

Hello,

This patch updates various variable and member names from class to
something (hopefully) more descriptive. This is a series of patches I
hope to submit to make it more compatible with C++ compilers.

I have compiled the this following list of targes and made sure that
"make check" produce the same result for all of them.

alpha-freebsd
alpha-linux
arc-elf
arm-eabi
arm-aout
cr16-linux
cris-linux
crx-linux
d30v-linux
dlx-elf
hppa-linux
i370-linux
i686-linux
x86_64-linux
i960-elf
ia64-linux
iq2000-elf
m32c-elf
m32r-linux
m68hc11-linux
m68k-linux
mcore-elf
mep-elf
mips-linux
mmix-linux
mn10300-linux
moxie-elf
ns32k-netbsd
pj-linux
ppc-linux
s390-linux
score-elf
sh-linux
sparc-linux
spu-elf
vax-linux

Thanks,
