Parts of Spidermonkey expect the bytecode length to always be non-zero.
Bug 1399373 shows crashes when this assumption fails. This patch moves
the check closer to source of error.

Several source files use DLL_PREFIX/DLL_SUFFIX defines, and they all
set them in moz.build using `DEFINES`. This is problematic for the WSL build
because the quoting gets lost somewhere between bash and cl.exe. This patch
makes them set globally in moz.configure with `set_define`. There was an
existing global `MOZ_DLL_SUFFIX` define that was only used in one place, so
that has been removed in favor of simply `DLL_SUFFIX`.

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.
