#338963 by thebuckst0p & hutch - Made default values for content type max num locations and max locations added at once to 1

#115323 by SeanA, catch, hutch - Allow option for display of state/province field, province name or province code

#503468 by hutch, sreynen, pingers, rooby - Make Google geocoding minimum accuracy a variable and allow country specific settings

Currently there is support for a location context (with keyword substitution,
so you can create a custom panel content item and format a location however
you want with keywords for each field), and a full-featured relationship to
create a location context from a node context.

Manual backport: Fix #367022, reported by amccann, patch by gapple: Use drupal_json to prevent issues with devel.

given in #412102

* Fix location_cck node deletion (Apparently this never worked in the first place.)
* Remove extra checks from location_cck that were working around a bug in location.
*
* Fix a few bugs in location_cck discovered while revamping the tests.
* location_is_empty() will now consider a node with the delete checkbox checked to be "empty."
* Change reorderLocations() in the test suite to work on CCK fields.

* Remove cck validator -- the condition it was checking for was a bug, not
a feature.

Add buttons to clear the location country support / province caches.

Augment instance_links by adding 'type', move the node and user implementations to where they belong.

Refactor RSS support to make it easier to reuse. *cough*cck georss support?*cough*

Fix tests to load location_node.

Split relevant uninstall sections out into location_node.install and location_user.install.

Fix #373723. This is a modified version of the patch I provided there, changed slightly to be appropriate for general inclusion.

* Add JIT geocoding. To use with bulk importing, set the source to 4 when inserting your locations into the {location} table, and enable JIT geocoding on the Location settings page.

Fix delete location checkbox when not collecting coordinates, due to a misplaced brace.

* Add 'nodiff' option to fields in the 'defaults' op of hook_locationapi().
  - This is needed to unbreak cow after the [#352550] change.
* Unbreak cow, again.

location_diff was conflicting with hook_diff(). It has been renamed to location_calc_difference()!
