LBER_OPT_MEMORY_FNS doesn't work at all.

In memory.c, it was checking the presence of both ber_int_memory_fns and ctx the
same time. However ctx was default to NULL all the time, so that's making this
option not working at all.

I suggest removing all ctx == NULL in memory.c, that way LBER_OPT_MEMORY_FNS
should work as intended. Right now, it's unusable. Thanks.
