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

revert an accidental ABI break

the new window manager code in 8.6.1 changed the prototype of an internal

this patch renames the function, adds it to an internal header instead,
and adds a stub for the old prototype
