This commit unregisters the viewport resize listener when setTarget(null) is called, and registers it when setTarget(target) is called, and when we don't have that listener registered yet.
This prevents memory leaks where references to map objects are retained because of these viewport resize listeners.
With this commit test files provide namespaces (using goog.provide). This fixes the issue reported by @bartvde where goog objects cannot be used in Jasmine "describe" functions. It also frees us from having to add script tags for the test files in test/ol.html.
The `window.location.search` string includes the "?" symbol. Without this change, `createFromQueryData` only works if the "renderer" parameter is not in first position (see 4037bafc45).
This rather large commit refactors the build system to solve a number of
problems:
- Object literal types are now declared in just one place
- There are no more circular dependencies
- There is no need for concealed subclasses in build-standalone mode
When building in standalone mode, you need to include the source in
build/src/external. This declares object literal types as externs so
that their properties are not renamed.
When building with the application, you need to include the source in
build/src/internal. This declares object literal types as typedefs so
that their properties can be renamed and removed.
Note also that ol.MapOptions has been merged into ol.Map, with some
renaming.
