And change `this.global.Object.create(null)` to
`Cu.createObjectIn(this.global)`. The tests pass either way, but
`Cu.createObjectIn` is more explicit.

Split the `shouldInject` method into separate methods:
- `shouldInject` to determine whether the API (or namespace)
should be injected.
- `getImplementation` to return the actual implementation.
Introduced `SchemaAPIInterface` for documentation purposes, and
two concrete implementations `LocalAPIImplementation` and
`ProxyAPIImplementation` which provide the functionality to run a local
and remote implementation of the API for which the schema API is
generated, respectively. These classes store the necessary details for
the invocation, so the methods that were formerly in the `Context` in
Schemas.jsm no longer get the `pathObj`, `path` or `name` parameters.
And merge the `path` and `name` in the implementation of remote APIs
because there is no need for having them separate, as the callers and
callees often did redundant pre/post-processing on `data.path` because
of the way it was implemented.

The API implementation is already available upfront when the schema API
is generated, so `pathObj` has the implementation and can be used
instead of looking up the implementation over and over again with
`findPathInObject`.

- Use schema-generated runtime API for content scripts instead of
untyped API.
- Move logic that cannot be run in the main process to a new file.
Together with the previous patch that migrated the i18n API, this
concludes the fix for bug 1286712.
MozReview-Commit-ID: A3yG0x1kjwx
- By default, schema APIs are not injected in content scripts unless
the JSON schema sets the "restrictions" attribute to `["content"]`.
- Added the "restrictions" attribute to the storage and test schemas.
Other APIs will follow in subsequent commits and make use of the
primitives introduced in this commit.

- Moved Management logic to ExtensionUtils (as SchemaAPIManager) so that
the logic can be used by addon and content processes.
- Remove the `context.extension.hasPermission(api.permission)` check in
`generateAPIs` because the only user (`registeredPrivilegedAPI`) was
removed before in bug 1295082.
- Add new category "webextension-scripts-content", intended for
registering the few scripts that must be loaded in a content process.
MozReview-Commit-ID: 81nhblV8YE6
- Add `envType` to BaseContext.
- Pass an explicit envType to all `registerSchemaAPI` invocations.
- The factories passed to `registerSchemaAPI` will be split up later, so
that content scripts (`content_child`) and addon pages can share
common implementations.
- The factories that implement the addon API will also be split up,
to separate code running in the main process (`addon_parent`) from
code running in a child process (`addon_child`).
- Remove the use of a hardcoded list of `namespaces` from ProxyContext.
Now `envType` is used to specify whether an API should be activated.

Local wrappers currently look up the API object over and over again
whenever a schema API is invoked. This can be optimized by re-using
the lookup result from a `shouldInject` invocation, which is passed
as the `pathObj` parameter to the wrapper methods.
This commit adds the necessary changes and tests to allow this to
happen, but does not modify the wrapper in Extension.jsm yet.
Also, this construction allows the `ChildAPIManager` to use a local
implementation if available and fall back to a remote implementation
otherwise.

Currently there is a tight coupling between registered APIs because they
share the same global scope, and the dependencies between the modules
that use these globals are not explicit. Consequently, it would be
possible for APIs to break when the registered APIs run in separate
processes, because then there are separate global scopes.
To mitigate this issue, this patch isolates the global namespaces of
API registrations in different environments, starting with the "chrome"
process. Content and addon processes will follow later.
A new JSM is introduced to avoid hidden dependencies between ext-*.js
and the script loader. ExtensionUtils.jsm would be a natural choice for
this shared utility method, but cannot be used because its local
`EventEmitter` implementation conflicts with the `EventEmitter` import
in ext-tabs.js.
So, this patch provides isolation of global variables declared through
`globals.XXX = ...`, but does not provide isolation for `Cu.import`-ed
logic. Ideally `Cu.import` should always use its second argument to
prevent inadvertent namespace pollution.

The presence of these globals interfere with the attempt to get ext-*.js
scripts to load in a content process because these globals are only
available in the main process.

The main motive for this patch is to remove the use of the GlobalManager
global (which was used to see if an extension ID is valid, which was
specifically added in order to create thebrowser_ext_lastError.js test).
To preserve test coverage I implemented a full validation of the
runtime.sendMessage method.
Now the error for a non-existent extension is identical in both the
content script and background pages. Note that this also fixes a
minor privacy leak: Previously extensions could see whether another
extension is installed by sending a message to the specified extension
and using the different responses to see whether another extension is
installed.

ExtensionContext in Extension.jsm has |extension| as an instance member,
so use it instead of passing |extension| to registerSchemaAPI's
callback.
And to make sure that this pattern also works in content processes, move
the |extension| member to BaseContext.

The tabs.sendMessage and runtime.sendMessage implementations behave like
an async function: They take a callback parameter and return a promise.
So they should be handled by |callAsyncFunction|, not
|callFunctionNoReturn|.
This fixes the issue for background pages, but not for content scripts
because sendMessage is not implemented as a schema at the moment. This
will also be fixed once content script APIs are generated via Schemas.

When we close the ExtensionContext at inner-window-destroyed instead of
unload, the browser_ext_getViews.js test fails due to the extension view
appearing again in getViews() immediately after "closing" the extension
button popup. With this change that test passes again.
