improve rounding in convi intize
...
We were rounding up with ceil() when intize-ing convolution masks.
However, the vector path has a true range of (1.0, -1.0], so a mask with
1.0 as the max (for example) was actually triggering the overflow detector
and falling back to the C path.
Round up with ceil(x + 1) instead, so 1.0 (for example) will be mapped
to 0.5 and won't overflow.

add sync locks to vips_sink()
...
vips_sink() used to just fire off threads willy nilly -- this could
cause problems with sequential images if a worker fell too far behind
the pack
copy over the area locking mechanism from vips_sink_memory(): new
threads are now stalled if an old thread has not finished
