Require C99 style flexible array member support after Git 3.0
boundary.
Comments?
* jc/c99-fam:
FLEX_ARRAY: require platforms to support the C99 syntax
Unless there are good reasons, it is customary to have the options[]
array used with the parse-options API declared in function scope rather
than at file scope.
Move builtin/pull.c:cmd_pull()’s options[] array into the function to
match that convention.

Before C99 syntax to express that the final member in a struct is an
array of unknown number of elements, i.e.,
struct {
...
T flexible_array[];
};
came along, GNU introduced their own extension to declare such a
member with 0 size, i.e.,
T flexible_array[0];
and the compilers that did not understand even that were given a way
to emulate it by wasting one element, i.e.,
T flexible_array[1];
As we are using more and more C99 language features, let's see if
the platforms that still need to resort to the historical forms of
flexible array member support are still there, by forcing all the
flex array definitions to use the C99 syntax and see if anybody
screams (in which case reverting the changes is rather easy).
