OSRM Release 5.0.0

Changes with regard 5.0.0 RC2:
- API:
 - if `geometry=geojson` is passed the resulting geometry can be a LineString or Point
   depending on how many coordinates are present.
 - the removal of the summary field was revered. for `steps=flase` the field will always be an empty string.

Changes with regard to 4.9.1:
- API:
 - BREAKING: Complete rewrite of the HTTP and library API. See detailed documentation in the wiki.

    - Instruction post-processing to merge unimportant instructions
    - Improved handling of roundabouts

- Tools:
 - BREAKING: Renamed osrm-prepare to osrm-contract

Changes since 4.9.1

- Renamed osrm-prepare into osrm-contract
- osrm-contract does not need a profile parameter anymore
- New public HTTP API, find documentation [here](https://github.com/Project-OSRM/osrm-backend/wiki/New-Server-api)
- POST support is discontinued, please use library bindings for more complex requests
- Removed timestamp plugin
- Coordinate order is now Longitude,Latitude
- Cucumber tests now based on Javascript (run with `npm test`)
- Profile API changed:
   - `forward_mode` and `backward_mode` now need to be selected from a pre-defined list
   - Global profile properties are now stored in a global `properties` element. This includes:
     - `properties.traffic_signal_penalty`
     - `properties.use_turn_restrictions`
     - `properties.u_turn_penalty`
     - `properties.allow_u_turn_at_via`

Known issues:
- Units uncovered that zero-length trips might have a duration bigger than zero Project-OSRM#2134
- pkg-config does not work as expected, include paths might be insufficient Project-OSRM#2195
- Position hint on requests with syntax error might be off Project-OSRM#2193

Release bug fix release v4.9.1

Fixes the following critical bugs:
- Project-OSRM#1850: Crash in trip service when specifing two coodinates

- Project-OSRM#1888: Race condition when running `osrm-datastore`
- Project-OSRM#1896: U-Turn error in one-way streets

4.9.0 Changelog

API changes:
- BREAKING: Changed response code for ok to `200`
- BREAKING: Fix off-by-one in via_indices (was one index too high)
- BREAKING: Removed `osrm/server_path.hpp`
- Add max value for viaroute and trip to osrm-routed. Default: 500 for viaroute and 100 for trip
- Allow POST request without POST data
- Add response code 208 for no segment found (important for bearing filter)
- New temporary file `.level` created by osrm-prepare (see level caching)
- New temporary file `.edge_segment_lookup` and `.edge_penalties` created by `osrm-extract` if passing the `--generate-edge-lookup` options.
- API grammar got more strict to discard invalid requests faster. Options like `hint`, `u` and `b` now need to follow directly after a `loc` (or `src` and `dst`). Example: `&loc=..&u=true&b=0,10&loc=...&u=false&loc=...`. The following is illegal: `&loc=..&loc=..&loc=...&b=0,10&u=true&u=false`.
- Pre-turn bearing is now available in the `route_instructions` array as last field
- Remove short option name `-m` from `osrm-routed` as it conflicted
- New option `--segment-speed-file` for `osrm-prepare`. CSV file using `from_osm_id;to_osm_id;edge_value`.

Bug fixes:
- Support 64bit OSM node ids
- Fixed u-turn penalty, value from lua profiles was not used
- Fix street name corruption for large datasets
- Properly initialize UUID used in Fingerprint class.  Fixes Project-OSRM#1721

Maintenance:
- Rewrite nearest neighbor search code
- Rewrite via-route search and fix multiple related bugs
- Add test for small component snapping
- Update variant library which fixes GCC 5.1.2 compile errors
- Silence warnings with GCC, LTO does not yet respect the -isystem switch
- Use ccache by default if available and a suitable compiler is used.
- Switch Travis builds over to trusty for Linux
- Fix pkgconfig cmake template

Features:
- Support general nxm queries to table query (thanks to @fab-girard) `loc`, `dst`, `src` parameters
- Add edge update step to `osrm-prepare`. Enables fast edge weight updates
- Add level caching `--level-cache` for `osrm-prepare`. This allows to speed up consecutive runs of `osrm-prepare` **on the same dataset** (only edge weights updates allowed).
- Small component size is now configurable over parameter for `osrm-routed`
- Support adding bearing filtering. Use `b=BEARING,RANGE`
- Add support for advisory speed limits
- Add duration and distance fields to `match` response
- Human-readable error messages for out of memory
- Include (road) name of matched nodes in addition to coordinate.
- Add `is_startpoint` property to `result` ways in the lua profiles. Determines if a way can be a start point for a route (e.g. is set to `false` for ferry ways).
