Avoid dangling pointers and array sizes.

Set the array size field to 0 if the allocation of the array fails or
when the array is freed.

Set the data pointer to NULL and the size field to 0 when we release a
frame buffer.

This is defensive programming. It also makes it less confusing when
the frame buffer structs are inspected in the debugger.
