We have a host of DEBUG-only dump()-style APIs that output either to
stderr or to a FILE*. Unfortunately, this means that we cannot use
these dumps e.g. for unit tests. This patch ports most of the dump()
APIs to use GenericPrinter, which is more flexible.

Some parts of the code have not been ported, in particular
TypeInference, which still uses stderr.

If you pass a string from script to an IDL method that takes an nsIAtom,
XPConnect will automagically atomize the string for you.

But nsIAtom is no longer scriptable (see the blockers for bug 1392883,
especially bug 1396694). So the code to convert can be removed.

This tests both that the settings have the desired effect and that switching
between sharing enabled and sharing disabled without a startup cache flush
does not cause any issues.

Tests for user pref changes are currently non-fatal, since they're known not
to work reliably.

User preference changes currently don't reliably take effect before component
loader initialization, which means they can't be used to write reliable tests.
Environment variables don't have this problem, so adding an environment
variable override makes testing much easier. It's also fairly convenient
during development, when we need to switch between different configurations
for testing.

Scripts for use in shared globals need to be compiled for non-syntactic
scopes, while scripts for standalone globals should be compiled as global
scripts for better performance.

Since the startup cache and script preloader store scripts as they were
compiled in the last session, when global sharing settings may have been
different, it can lead to a mismatch, and a crash, due to loading the wrong
type of script.

Using a separate cache path for each type of script fixes this problem, since
it ensures that the cached script will always be of the type we expect.

The files relevant to the memory allocator are currently spread between
memory/mozjemalloc and memory/build, and the distinction was
historically from sharing some Mozilla-specific things between
mozjemalloc and jemalloc3. That distinction is not useful anymore, so
we fold everything together.

As we will likely rename the allocator at some point in the future, it
is preferable to move away from the mozjemalloc directory rather than in
its direction.

When using the subscript loader with JSM global sharing, it was possible
that subscript would pollute the global of all JSMs in the sharing.

We want to be able to store scripts compiled with or without
non-syntactic support in cache when we toggle JSM global sharing. In
current code this script is cloned on execution, but with JSM global
sharing we have would hit assertions.

This allows js::ExecuteInJSMEnvironment to take a target object argument
as used by the subscript loader. This adds WithEnvironments with a
corresponding lexical on top of the ordinary NonSyntacticVariablesObject
environment chain.
