I generally tried to preserve the behavior of consumers where they treated an
exception from getInterface(Ci.nsIContentFrameMessageManager) as a signal to use
some sort of fallback.
I did change the behavior of consumers that walked up to the root same-type
docshell before getting the message manager to just get it directly from the
docshell they have. Please review those parts carefully, and let me know if you
want me to ask some subject area experts to review those.

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 {, <
