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

tidwall 23b016d192 Fix excessive memory usage for objects with TTLs 
This commit fixes an issue where Tile38 was using lots of extra
memory to track objects that are marked to expire. This was
creating problems with applications that set big TTLs.

How it worked before:

Every collection had a unique hashmap that stores expiration
timestamps for every object in that collection. Along with
the hashmaps, there's also one big server-wide list that gets
appended every time a new SET+EX is performed.

From a background routine, this list is looped over at least
10 times per second and is randomly searched for potential
candidates that might need expiring. The routine then removes
those entries from the list and tests if the objects matching
the entries have actually expired. If so, these objects are
deleted them from the database. When at least 25% of
the 20 candidates are deleted the loop is immediately
continued, otherwise the loop backs off with a 100ms pause.

Why this was a problem.

The list grows one entry for every SET+EX. When TTLs are long,
like 24-hours or more, it would take at least that much time
before the entry is removed. So for databased that have objects
that use TTLs and are updated often this could lead to a very
large list.

How it was fixed.

The list was removed and the hashmap is now search randomly. This
required a new hashmap implementation, as the built-in Go map
does not provide an operation for randomly geting entries. The
chosen implementation is a robinhood-hash because it provides
open-addressing, which makes for simple random bucket selections.

tidwall 6257ddba78 Faster point in polygon / GeoJSON updates 
The big change is that the GeoJSON package has been completely
rewritten to fix a few of geometry calculation bugs, increase
performance, and to better follow the GeoJSON spec RFC 7946.

GeoJSON updates

- A LineString now requires at least two points.
- All json members, even foreign, now persist with the object.
- The bbox member persists too but is no longer used for geometry
  calculations. This is change in behavior. Previously Tile38 would
  treat the bbox as the object's physical rectangle.
- Corrections to geometry intersects and within calculations.

Faster spatial queries

- The performance of Point-in-polygon and object intersect operations
  are greatly improved for complex polygons and line strings. It went
  from O(n) to roughly O(log n).
- The same for all collection types with many children, including
  FeatureCollection, GeometryCollection, MultiPoint, MultiLineString,
  and MultiPolygon.

Codebase changes

- The pkg directory has been renamed to internal
- The GeoJSON internal package has been moved to a seperate repo at
  https://github.com/tidwall/geojson. It's now vendored.

Please look out for higher memory usage for datasets using complex
shapes. A complex shape is one that has 64 or more points. For these
shapes it's expected that there will be increase of least 54 bytes per
point.
