pgtls_read_pending is declared to return bool, but what the underlying
SSL_pending function returns is a count of available bytes.
This is actually somewhat harmless if we're using C99 bools, but in
the back branches it's a live bug: if the available-bytes count happened
to be a multiple of 256, it would get converted to a zero char value.
On machines where char is signed, counts of 128 and up could misbehave
as well. The net effect is that when using SSL, libpq might block
waiting for data even though some has already been received.
