[PATCH] objects: scope count variable to loop

[Stefan Beller <sbeller@google.com>]

This is another test balloon to see if we get complaints from people
whose compilers do not support variables scoped to for loops.

This part of the code base was chosen as it is very old code that does
not change often, such that a potential revert is easy.

This is a rather aggressive test ballon, my compiler needed some
good arguments to accept the new world order:

object.c: In function ‘object_array_remove_duplicates’:
object.c:404:2: error: ‘for’ loop initial declarations are only allowed in C99 mode
  for (unsigned src = 0; src < nr; src++) {
  ^
object.c:404:2: note: use option -std=c99 or -std=gnu99 to compile your code

Using -std=c99 works for me.

Thanks,
Stefan
