Mike Poindexter 2a4272c95f Improve kNN behavior 
The current KNN implementation has two areas that can be improved:

- The current behavior is somewhat incorrect. When performing a kNN
query, the current code fetches k items from the index, and then sorts
these items according to Haversine distance. The problem with this
approach is that since the items fetched from the index are ordered by
a Euclidean metric, there is no guarantee that item k + 1 is not closer
than item k in great circle distance, and hence incorrect results can be
returned when closer items beyond k exist.

- The secondary sort is a performance killer. This requires buffering
all k items (again...they were already run through a priority queue in)
the index, and then a sort. Since the items are mostly sorted, and
Go's sort implementation is a quickSort this is the worst case for the
sort algorithm.

Both of these can be fixed by applying a proper distance metric in
the index nearby operation. In addition, this cleans up the code
considerably, removing a number of special cases that applied only
to NEARBY operations.

This change implements a geodetic distance metric that ensures that
the order from the index is correct, eliminating the need for the
secondary sort and special filtering cases in the ScanWriter code.

tidwall ff48054d3d Fixed a missing faraway event for roaming geofences 
This commit fixes a case where a roaming geofence will not fire
a "faraway" event when it's supposed to.

The fix required rewriting the nearby/faraway detection logic. It
is now much more accurate and takes overall less memory, but it's
also a little slower per operation because each object proximity
is checked twice per update. Once to compare the old object's
surrounding, and once to evaulated the new object. The two lists
are then used to generate accurate "nearby" and "faraway" results.

tidwall 66af8ab094 Fix tile38-cli from freezing with non-quoted geojson 
This commit addresses an issue that began on 1.19 where the
deprecated tile38 native line protocol was removed in favor of
the more robust resp protocol. In turn the tile38 cli required
that all args are quoteless or quote escaped.

The commit ensures that the server returns the correct error
message and also loosens the strictness of the need for quoted
arguments in the tile38-cli.

tidwall cfc65a13f6 Refactor repository and build scripts 
This commit includes updates that affects the build, testing, and
deployment of Tile38.

- The root level build.sh has been broken up into multiple scripts
  and placed in the "scripts" directory.

- The vendor directory has been updated to follow the Go modules
  rules, thus `make` should work on isolated environments. Also
  some vendored packages may have been updated to a later
  version, if needed.

- The Makefile has been updated to allow for making single
  binaries such as `make tile38-server`. There is some scaffolding
  during the build process, so from now on all binaries should be
  made using make. For example, to run a development version of
  the tile38-cli binary, do this:
     make tile38-cli && ./tile38-cli
  not this:
     go run cmd/tile38-cli/main.go

- Travis.CI docker push script has been updated to address a
  change to Docker's JSON repo meta output, which in turn fixes
  a bug where new Tile38 versions were not being properly pushed
  to Docker
