[GIT PULL] Add -Wmissing-prototypes to HOSTCFLAGS; fix resulting warnings

[Josh Triplett]

In an effort to slow the continuous need for "make foo static" patches,
I'd like to work towards using GCC's -Wmissing-prototypes flag, which
generates a warning for any function not declared static or previously
prototyped.  This works much like Sparse's -Wdecl, though only for
functions, not variables.

As a start, I've fixed all such warnings that remain in host programs,
including generated code, and added -Wmissing-prototypes to HOSTCFLAGS
to try to keep it that way.  (Long-term, I think it may prove reasonable
to use -Werror=missing-prototypes.)

Please pull from:

git://git.kernel.org/pub/scm/linux/kernel/git/josh/linux-misc hostprogs-wmissing-prototypes

As seen in the diffstat below, this represents almost exclusively
one-liner fixes, with the exception of the .c_shipped files generated by
flex/bison/gperf.  The diffstat for the corresponding input files
remains small.

I believe these changes seem sufficiently obvious to go into .32, and I
also think doing so would make it easier for any -Wmissing-prototypes
warnings in .33-targeted trees to get fixed before the next merge
window, rather than during the middle of it.

I've confirmed that this branch merges into current master cleanly, and
that no new warnings exist in current master.
