When ReadSegments is called before the stream is ready, we return NS_BASE_STREAM_WOULD_BLOCK, not NS_ERROR_NOT_IMPLEMENTED.
If callers use AsyncWait for the IPCBlobInputStream to be ready, and then call ReadSegments again we can end up returning NS_ERROR_NOT_IMPLEMENTED, depending on what the inner type is.

Most of these tests have been disabled for a long time; they run well
in the current test environment.
I intend to enable still more mochitests in a future patch.

We want to remove flat strings (JSFlatString). With this patch we only expose
linear strings (JSLinearString) to API consumers.
This is very mechanical for the most part, because code typically only cares
about linear strings and not the null-termination aspect.
CTypes's Library.cpp has some Windows-specific code where we relied on null-terminated
strings. This patch adds JS_CopyStringCharsZ for that use case.

When we have a parser-created iframe which starts out in-process, transitions
to remote, and then transitions back to in-process, we create separate
DocShells for the first and last in-process loads. Since both are
network-created, and have the same child index, they both try to add
themselves as children to their parent's SHistory at the same index. And since
the entry for the first DocShell already exists at that index when we try to
add the second, that triggers an assertion.
This isn't really ideal, but it is expected given the current state of session
history under Fission. It should hopefully be solved more gracefully when the
Fission-aware session history rewrite is done, but in the mean time, I think
we should just ignore the conflict, since it's expected.

This patch cleans up remote outer window proxies when we navigate back
into the process.
It adds a flag to mDanglingRemoteOuterProxies that is set in between
BrowsingContext::SetDocShell(), where we can tell that the browsing
context is going from being remote to being local, to
nsGlobalWindowOuter::SetNewDocument(), where the local outer window
proxy is actually created. Once the outer window is created, the
remote window proxies can be cleaned up in
CleanUpDanglingRemoteOuterWindowProxies().
The clean up is done by a process that is similar to object
transplanting, except that instead of looking in the cross-compartment
wrapper table for each compartment to find objects to be turned into
CCWs to the new object, it looks in the remote proxy map for each
compartment. SpiderMonkey doesn't know about the proxy maps, so this
has to be done by a new callback object CompartmentTransplantCallback.
Now that this cleanup is being done, it shouldn't be possible to wrap
a remote outer window proxy when the browsing context is local, so
MaybeWrapWindowProxy() can be simplified. I had to drop the assert
here that the browsing context has a window proxy because during clean
up we call wrap on a local outer window proxy before the BC gets the
window proxy set on it. I had the assert because my original plan was
to implicitly fix remote proxies during wrapping, but that is no
longer necessary.

This requires replacing inclusions of it with inclusions of more specific prefs
files.
The exception is that StaticPrefsAll.h, which is equivalent to StaticPrefs.h,
and is used in `Codegen.py` because doing something smarter is tricky and
suitable for a follow-up. As a result, any change to StaticPrefList.yaml will
still trigger recompilation of all the generated DOM bindings files, but that's
still a big improvement over trigger recompilation of every file that uses
static prefs.
Most of the changes in this commit are very boring. The only changes that are
not boring are modules/libpref/*, Codegen.py, and ServoBindings.toml.

When a test crashes, the harness skips all of the remaining tests in the
directory. That means that with crashes skipped, we now try to run a whole lot
more tests than we did before, and a lot of them fail under Fission.
This patch adds annotations to the new failures that show up after part 1.

My preference was to annotate most of the failing tests with `fail-if` so that
if they start passing, the `fail-if` needs to be removed and they need to keep
passing. That doesn't work for tests that timeout, or which trigger failures
from their cleanup functions, however, so those tests need skip-if. And tests
with fail in their cleanup functions likely leave the browser in an
inconsistent state for subsequent tests, anyway, so really should be skipped
regardless.
There are some remaining tests which still fail because of crashes. I chose
not to skip them here, but to fix the crashes in separate bugs instead.
