constify to_detach

This patch constifies the target_ops method to_detach.

This is a small cleanup, but also, I think, a bug-prevention fix,
since gdb already acts as if the "args" argument here was const.

In particular, top.c:quit_force calls kill_or_detach via
iterate_over_inferiors.  kill_or_detach calls target_detach, passing
the same argument each time.  So, if one of these methods was not
const-correct, then kill_or_detach would change its behavior in a
strange way.

I could not build every target I modified in this patch.  I've
inspected them all by hand, though.  Many targets do not use the
"args" parameter; a couple pass it to atoi; and a few pass it on to
the to_detach method of the target beneath.  The only code that
required a real change was in linux-nat.c, and that only needed the
introduction of a temporary variable for const-correctness.

introduce common.m4

It has bothered me for a while that files in common/ use macros
defined via autoconf checks, but rely on each configure.ac doing the
proper checks independently.

This patch introduces common/common.m4 which consolidates the checks
assumed by code in common.

The rule I propose is that if something is needed or used by common,
it should be checked for by common.m4.  However, if the check is also
needed by gdb or gdbserver, then it should be duplicated there.

Built and regtested on x86-64 Fedora 18 (though this is hardly the
most strenuous case) and using the Fedora 18 mingw cross compilers.  I
also examined the config.in diffs to ensure that symbols did not go
missing.

	* common/common.m4: New file.

remove link.h checks

The removal of solib-sunos.c also removed the last user of various
macros defined by configure.

This patch removes the corresponding configure code.

use gdb_string.h in m32c-tdep.c

m32c-tdep.c is the last user of HAVE_STRING_H in gdb proper.  It
really ought to be using gdb_string.h instead, as the rest of gdb
does.

2013-11-08  Tom Tromey  <tromey@redhat.com>

	* m32c-tdep.c: Use gdb_string.h.
gdb configure updates

Now that the configury needed for the "common" and "target"
directories is in common.m4, some code in gdb's configure.ac is
redundant.

I ran this script after making an "ID" file using mkid:

   sed -n 's/^.*\(HAVE_[A-Z0-9_]*\).*$/\1/p' config.in |
   while read x; do
     echo ===== $x
     gid $x | egrep -v '^(testsuite|gnulib|common|target|gdbserver)/'
   done

This finds all the spots using HAVE_ defines, and, more importantly,
makes it clear which defines aren't used in the main parts of gdb.

From this I came up with this patch to remove all the unused bits.

There are a few that are subtly used -- for example the configure
script sometimes checks internal configure cache variables, meaning
some checks cannot be removed.

	* configure, config.in: Rebuild.
	* configure.ac: Remove unused configury.
