Implement raster source feature to read data from third-party sources, to be used in lua profiles.

Browse Source 
* Adds a data structure, RasterSource, to store parsed + queryable data
* Adds bindings for that and relevant data structures as well as source_function and segment_function
* Adds relevant unit tests and cucumber tests
* Bring-your-own-data feature

Feature: Raster - weights
Background: Use specific speeds
Given the node locations
| node | lat | lon |
| a | 0.1 | 0.1 |
| b | .05 | 0.1 |
| c | 0.0 | 0.1 |
| d | .05 | .03 |
| e | .05 | .066 |
| f | .075 | .066 |
And the ways
| nodes | highway |
| ab | primary |
| ad | primary |
| bc | primary |
| dc | primary |
| de | primary |
| eb | primary |
| df | primary |
| fb | primary |
And the raster source

Scenario: Weighting not based on raster sources
Given the profile "testbot"
When I run "osrm-extract {osm_base}.osm -p {profile}"
And I run "osrm-prepare {osm_base}.osm"
And I route I should get
| from | to | route | speed |
| a | b | ab | 36 km/h |
| a | c | ab,bc | 36 km/h |
| b | c | bc | 36 km/h |
| a | d | ad | 36 km/h |
| d | c | dc | 36 km/h |
Scenario: Weighting based on raster sources
Given the profile "rasterbot"
When I run "osrm-extract {osm_base}.osm -p {profile}"
Then stdout should contain "evaluating segment"
And I run "osrm-prepare {osm_base}.osm"
And I route I should get
| from | to | route | speed |
| a | b | ab | 8 km/h |
| a | c | ad,dc | 15 km/h |
| b | c | bc | 8 km/h |
| a | d | ad | 15 km/h |
| d | c | dc | 15 km/h |
| d | e | de | 10 km/h |
| e | b | eb | 10 km/h |
