Fix integer overflow in subvector() function ( #530 )
...
`end = start + count` can overflow if `start` is very large. That
leads to a segfault later in the function. Add test case for it.

Forbid zero values in sparsevec's binary input function ( #528 )
...
The text input function simply left out any zero values, but the
binary input function did not. That's problematic because you end up
with an "unnormalized" sparse vector, which behaves in weird ways. At
least sparsevec_cmp_internal() expects both inputs to not contain
zeros.
The binary send function never produces such zero values, but an
external tool could. Or to test, you can use COPY TO (FORMAT BINARY),
use a hex editor to edit one of the values to be zero, and copy it
back with COPY FROM (FORMAT BINARY).
