_bcp_get_term_data is passed a buffer into which it places a column's
worth of data.  It is not told how big the buffer is, and the caller
allocates only 4096 bytes, statically.  

I changed the signature to accept an array of pointers, the first of which
is allocated by the caller.  If _bcp_get_term_data requires more room, it
allocates subsequent members of the array in 1 MB chunks.  The array has
1000 pointers; if it's exhausted, we need more address space.  The caller
knows from the returned size how many buffers (if any) were allocated.  

I haven't committed yet because it doesn't work yet.  I just wanted you to
know I've isolated the problem and solved it, in principle.
