swscale: fix overflow in 16-bit vertical scaling.
...
We operated on 31-bits, but with e.g. lanczos scaling, values can
add up to beyond 0x80000000, thus leading to output of zeroes. Drop
one bit of precision fixes this.

swscale: fix 16-bit horizontal scaling underflow.
...
When using e.g. lanczos scaling, values can drop below 0, so they
should never be unsigned.

swscale: fix 16-bit scaling when output is 8-bits.
...
We would use the second half of the U plane buffer, rather than the
V plane buffer, to output the V plane pixels.

swscale: implement >8bit scaling support.
...
This means that precision is retained when scaling between sample
formats with >8 bits per component (48bit RGB, 16bit grayscale,
9/10/16bit YUV).
