GeoclueWebService class
  a) notifies about connection changes
  b) makes web service interaction easier
See backend/common/geoclue_web_service.h for more info

I had forgotten add real civic location signal emission to the
backends. position example bailed out when status or current_position
failed: this is not always wanted

Merge branch 'master' of ssh://git.freedesktop.org/git/geoclue

Conflicts:

	backend/position_manual/geoclue_position_server_manual.h

Manual backend now fetches position data from gconf. Any program
can modify that data (although data should be modified only by user
request), this backend does not modify it.

Initial commit. Should work but needs work...

Note that system bus needs to be set on a gconf key also

Change to the Satellite Data Method, it is now one method for grabbing all the satellite data.   Previously it took 13 round trip calls to generally get satellite information which is just slow.   Changed the backends to have the new proper method.

World's largest Change.....  Updated Position API to hopefully useful and stable point.   All the backends have gotten upgraded to the new api.   Still need to do some work with geoclue master forwarding request, but currently you must manually specify the backend AKA look at geoclue-position-example hostip

This was somehow missing from the first version

Commit includes implementation for hostip-backend.

Too greedy .gitignore-rule made git ignore all *.in files...

forgot to 'git add' Makefile.am and position_plazes.desc

returns booleans: TRUE for for all the data items that the
backend may return on a civic_location-method call, FALSE for all
the data items that are not supported.

plazes requires the MAC address to be in lowercase

Small modifications so that the private helper functions
are identical in the two backends. The functions can now
be moved to a single file.

This is modified from hostip-backend, at the moment it's
mostly copy-pasted: should refactor that.
The current version supports civic location (country, locality,
postalcode, street, text), but not connectivity event monitoring
(libconic).

  * basic "civic_location" method added, also to the C-wrapper
  * hostip supports country, locality (=city)
  * gpsd returns "not supported", manual returns "not supported yet"

Coming Soon
  * civic_location_changed-signal
  * libconic support (like current_position)
  * some convenience methods

Splitting functions, removed unnecessary includes, used proper
libxml2 functions instead of a couple of hacks.

hostip position backend now works with libconic if it is present:
It queries the position from hostip.info whenever there is a new
network connection and saves it. Saved data is considered valid
as long as the connection is alive. This means that
   a) current_position method has no network latency
   b) position_changed events are fired

Didn't touch backend/geoclue_master or backend/position_plazes.

did not go through backends/ yet.

backend/geoclue_position_error.[ch] define an error type
for position errors. All position backends should use
GeocluePositionError.

Previously signal was emitted if any data was updated by gpsd.
Now it's emitted when lat/lon is updated.

It _should_ be emitted only when lat/lon are different
than last time.

note to self: do not commit stuff that has not been built on all platforms...

* Better output
* now accepts (optional) backend to use, e.g.
     ./geoclue-position-example gpsd
