DocShells are associated with outer DOM Windows, rather than Documents, so
having the getter on the document is a bit odd to begin with. But it's also
considerably less convenient, since most of the times when we want a docShell
from JS, we're dealing most directly with a window, and have to detour through
the document to get it.

This only changes some variable names. There is still work to do,
e.g. renaming "extension" in WebExtensionContentScript to "policy".
That will be handled in bug 1441886.

initialProcessData has the unfortunate side-effect of sending an entire copy
of all of its data to all content processes, and eagerly decoding it. For the
extension framework, this means that we wind up loading an entire copy of all
of our schema data, and of every extension's manifest and locale data, into
every process, even if we'll never need it.
The sharedData helper allows us to store an encoded copy of that data in a
shared memory region, and clone it into the current process only when we need
it, which can be a significant savings. For screenshots alone, it saves about
15K on locale and manifest data per content process, plus the size we save on
not copying schema data.

The schema handling for this is currently a bit ugly, for the sake of
simplifying uplift. In the figure, we should find a way to change the schema
pattern matching based on whether or not the extension is privileged.

This also removes any redundant Ci.nsISupports elements in the interface
lists.
This was done using the following script:

This patch was autogenerated by my decomponents.py
It covers almost every file with the extension js, jsm, html, py,
xhtml, or xul.
It removes blank lines after removed lines, when the removed lines are
preceded by either blank lines or the start of a new block. The "start
of a new block" is defined fairly hackily: either the line starts with
//, ends with */, ends with {, <![CDATA[, """ or '''. The first two
cover comments, the third one covers JS, the fourth covers JS embedded
in XUL, and the final two cover JS embedded in Python. This also
applies if the removed line was the first line of the file.
It covers the pattern matching cases like "var {classes: Cc,
interfaces: Ci, utils: Cu, results: Cr} = Components;". It'll remove
the entire thing if they are all either Ci, Cr, Cc or Cu, or it will
remove the appropriate ones and leave the residue behind. If there's
only one behind, then it will turn it into a normal, non-pattern
matching variable definition. (For instance, "const { classes: Cc,
Constructor: CC, interfaces: Ci, utils: Cu } = Components" becomes
"const CC = Components.Constructor".)

This patch introduces a cache of blob urls which are related to the cssCode
injected by the extensions using tabs.insertCSS, which aims to reduce the
amount of memory used by the extensions to store the cssCode injected
into the tabs and their subframes in the content child process.
The generated Blob URL are associated to the extension principal,
so that it is easier to identify in the about:memory reports
which is extension that is using the cached data.

Web contetnt processes only need access to a small amount of schema data, but
we currently send them the approximately 600K of full schema data that is
mostly useless to them.
This patch limits the schema data sent to web content processes to what they
actually need, and sends the rest only to extension content processes.

This replaces the JS policy service stubs with a pure C++ version which
directly makes policy decisions based on active WebExtensionPolicy objects.
This is the first step in a larger refactoring, which will remove the
ExtensionManagement module entirely, and replace the current add-on policy
service with direct, non-virtual access to native WebExtensionPolicy objects.
It will also be followed by related changes to migrate the content script and
extension page matching to native code, based on the existing MatchPattern and
WebExtensionPolicy bindings.
