The code interacting with the test runners now resides in closer
proximity to the code it is invoking. We also purge testing
functionality from mozbuild, which is where it never really belonged.

Each nsCSSStyleSheet has a pointer to a nsCSSStyleSheetInner. The
nsCSSStyleSheetInner is shared across multiple stylesheets, in
general. The nsCSSStyleSheetInner owns the rules and the child
stylesheets.
What this means is that a given rule object is effectively owned by
multiple sheets. However, cycles can only form through rule objects
that have been JS-wrapped, and if we're JS-wrapping a rule object that
means we have ensured that it's owned by only one stylesheet.
Therefore, we only traverse and unlink mInner if it's uniquely owned
by our sheet.
Similarly, if our child sheets or any of their rules have been
JS-wrapped, that means that we must have an mInner that we own
outright.
This swap was removed with the work in Bug 785333, as layers were associated
with merged frames as well as their underlying frames. Since DLBI, this is no
longer the case, so reinstate this temporary fix for a very common case of
the underlying frame of a display-item changing.
This creates a new method 'StartDecoding' which does a RequestDecode and some
decoding of the image.

It turns out that relying on the user to check return codes for every
command was non-intuitive and resulted in many hard to trace bugs.
Now most functinos just return "None", and raise a DMError when there's an
exception. The exception to this are functions like dirExists, which now return
booleans, and throw exceptions on error. This is a fairly major refactor,
and also involved the following internal changes:
* Removed FileError and AgentError exceptions, replaced with DMError
(having to manage three different types of exceptions was confusing,
all the more so when we're raising them)
* Docstrings updated to remove references to return values where no
longer relevant
* pushFile no longer will create a directory to accomodate the file
if it doesn't exist (this makes it consistent with devicemanagerADB)
* dmSUT we validate the file, but assume that we get something back
from the agent, instead of falling back to manual validation in the
case that we didn't
* isDir and dirExists had the same intention, but different
implementations for dmSUT. Replaced the dmSUT impl of getDirectory
with that of isDir's (which was much simpler). Removed
isDir from devicemanager.py, since it wasn't used externally
* killProcess modified to check for process existence before running
(since the actual internal kill command will throw an exception
if the process doesn't exist)
In addition to all this, more unit tests have been added to test these
changes for devicemanagerSUT.
