XCTest apparently no longer executes tests in alphabetical order, so naming the test testAAALoadPacks doesn’t ensure it gets run first. Instead, put the pack loading test inside -setUp, but also put it inside a dispatch_once() block to ensure that it only gets run before the first offline storage test that gets run in the current process.
We cannot guarantee that the offline/ambient tile cache (cache.db) will be created in a timely manner, so it's safer to set the backup exclusion key on its containing directory.
But, because we placed cache.db in the base of the app's Application Support directory (where backups are expected to be allowed), we need to move cache.db into a directory that we control and can exclude from backups with impunity.
This is an amalgam of https://github.com/mapbox/mapbox-gl-native/pull/5578 (directory exclusion) and https://github.com/mapbox/mapbox-gl-native/pull/5585 (refactored URL methods, but without the new database size method).
Also:
* Prefix mapbox subdirectory with dot, for extra safety
* Update changelog entry with new ticket, less speculation
Updated default styles from v8 to v9. Deprecated the MGLMapView class methods in favor of new methods that take a version parameter. Deprecated Emerald outright in favor of Outdoors. Replaced usage of the unversioned MGLStyle methods with the corresponding versioned methods and MGLStyleCurrentVersion to ensure consistency.
Expanded MGLStyle unit tests to also assert that MGLStyle has the right number of style URL methods and that they’re all public. Linked the OS X SDK unit test bundle to libmbgl-core.a. Removed an unnecessary dependency on osxapp.
Replaced Emerald with Outdoors in iosapp and osxapp.
Fixes the iOS and OS X side of #4577 and #4702.
Now that #4641 has removed the prohibition against C99 extensions, this change removes many pragma statements that suppress warnings about variadic macros and designated initializers. Designated initializers and Elvis operators have been introduced wherever appropriate.
For some reason, the SDK tests are less accurate when run on the command line than when run in Xcode or on OS X.
Also fixed unused variable warnings in the tests.
The iOS and OS X SDKs now share a non-UI test bundle. Moved the iOS UI test bundle into a uitest/ subdirectory and moved the OS X SDK tests into the darwin/ subdirectory.
Upgraded KIF to v3.4.2.
