Clear up some confusion about attribute count and external references
...
Now the count is always adjacent to whereever the key/value pair is
stored, and is not kept in the serial feature object other than as
the length of the vectors of keys and values.

Allow filtering features by zoom level in conditional expressions
...
This moves filtering from the serialization stage to the
tiling stage so that the zoom level can be known to the filter.
The side effect is to carry null attributes much further through
the pipeline than previously.

Fortunately most attributes are in the string pool, but ones that
have passed through the prefilter are not. (Nor are attributes that
are generated by clustering or by attribute accumulation.)

Send dot-dropping through the same pipeline.
...
The first feature in a tile can never be dropped, since there is
no previous feature to attach its properties to.
Remove the previous special case that reset the dropping counter
at the first feature within each tile proper (as opposed to the
first feature in each tile, including its buffer, which is now
the one that is guaranteed to be preserved).
