Geoclue2 merge into Geoclue master

[Bastien Nocera]

Heya,

git magic tricks happened, and Zeeshan's geoclue2 work has been merged
into geoclue master on freedesktop.org.

Version was bumped to 1.99.0 (leading the way to a real "geoclue 2"
release). This first version is a tech demo for the new API, and is used
by the GNOME Maps application.

The next version will move IP geolocation client and server code from
geocode-glib to geoclue proper, and we'll enable Wi-Fi geolocation.
After that, support for 3G modems will be worked on, using
ModemManager's recently released 1.0 API.

Cheers
