Adding a new attribute to the panel was the easiest way I could find to make this work without too much plumbing
However I don't know how to check that the attribute comes from a chrome privileged script. I tried using PresContext()->IsChrome() but this is also false in our situation.
Would you prefer another approach? Otherwise what kind of test would you write for this kind of feature?

Because not all static components are using the static registration yet,
we can end up in situations where a same component is registered
multiple times, which can have some unexpected consequences.
Interestingly enough, this change revealed that we did have static
registration in place for components that were kept under the old system
after bug 1478124 and bug 1524687.
There are also possibly some non-obvious things that can happen while
migrating the remaining components, like what happened to me while I
worked on @mozilla.org/widget/components;1 (see bug 1542214 comment 0).

Whenever chrome JS code leaks, we leak the dynamic atom "[System
Principal]". This causes an assertion, which hangs the browser in
stack walking code for multiple minutes on OSX. As a bandaid, make
this atom static so it won't leak.
My first instinct is that it would make sense to use this new atom
directly in SystemPrincipal, but atoms are represented internally as a
kind of nsAString, but principal code uses nsACStrings, so you end up
with an extra conversion from 16-bit to 8-bit.
This atom is also going to be present in any process running chrome
JS, so this will save a little bit of memory.

Before bug 938437, we had a rather large and error-prone
nsStaticXULComponents.cpp used to register all modules. That was
replaced with clever use of the linker, which allowed to avoid the mess
that maintaining that file was.
Fast forward to now, where after bug 1524687 and other work that
preceded it, we have a much smaller number of remaining static xpcom
components, registered via this linker hack, and don't expect to add
any new ones. The list should eventually go down to zero.
Within that context, it seems to be the right time to get rid of the
magic, and with it the problems it causes on its own.
Some of those components could probably be trivially be converted to
static registration via .conf files, but I didn't want to deal with the
possible need to increase the number of dummy modules in XPCOMInit.cpp.
They can still be converted as a followup.

I am 90% sure that this is wrong but this is the only way I can get it to
compile and work. Unlike other examples of supporting MOZ_DBG it only declares
an operator for `nsIURI* not` `const nsIURI`. I had to drop the const because
then I couldn't call GetSpec as it isn't marked const. I had to switch to a
pointer since otherwise it would complain about virtual methods.
Still in practice this works, I think it is rare that we hold an nsIURI in
anything other than a pointer and same for the constness.

we reload the install data from installs.ini and put it back into profiles.ini.

This commit adds `ThreadPtr{Handle, Holder}` to wrap an `XpCom` object
with thread-safe refcounting. These are analagous to
`nsMainThreadPtr{Handle, Holder}`, but can hold references to
objects from any thread, not just the main thread.
`ThreadPtrHolder` is similar to `ThreadBoundRefPtr`. However, it's
not possible to clone a `ThreadBoundRefPtr`, so it can't be shared
among tasks. This is fine for objects that are only used once, like
callbacks. However, `ThreadBoundRefPtr` doesn't work well for loggers
or event emitters, which might need to be called multiple times on
the owning thread.
Unlike a `ThreadBoundRefPtr`, it's allowed and expected to
clone and drop a `ThreadPtrHolder` on other threads. Internally,
the holder keeps an atomic refcount, and releases the wrapped object
on the owning thread once the count reaches zero.
This commit also changes `TaskRunnable` to support dispatching from
threads other than the main thread.

This commit wraps just enough of the mozStorage API to support the
bookmarks mirror. It's not complete: for example, there's no way
to open, clone, or close a connection, because the mirror handles
that from JS. The wrapper also omits shutdown blocking and retrying on
`SQLITE_BUSY`.
This commit also changes the behavior of sync and async mozStorage
connections. Async (`mozIStorageAsyncConnection`) methods may be called
from any thread on any connection. Sync (`mozIStorageConnection`)
methods may be called from any thread on a sync connection, and from
background threads on an async connection. All connections now QI
to `mozIStorageConnection`, but attempting to call a sync method on
an async connection from the main thread throws.
Finally, this commit exposes an `OpenedConnection::unsafeRawConnection`
getter in Sqlite.jsm, for JS code to access the underlying connection.

Before the Array<T> type, the calltype argument could be in, out, or inout,
however with Array<T> the element type was added.
When I added Array<T>, I changed the checks in files which check calltype !=
'in' to instead check 'out' in calltype, such that element would act more like
in in most cases (not adding the outparam *).
However, I never made that change for rust code, as it didn't support Array<T>
at the time. When I turned on Array<T> support for rust code, I forgot to go
through and change the conditions, which lead to this bug.

The old code for member method calls did the following:
1) Find the member method calls.
2) Look at their "this" expression.
3) If the "this" is an operator call, check for any of the arguments of the
operator call being invalid.
4) Otherwise (if not an operator call) check for the "this" value being
invalid.
This wasn't right, because the "is invalid" check checks the type and only
considers refcounted things. So if the code looked something like
"foo[i]->call_method()", we would look at the types of "foo" and "i" and
determine that none of those are refcounted types so there is nothing invalid
here (since "foo" is some sort of array type and "i" is an integer). The new
setup just checks whether the "this" value is invalid, which does the type
check on the "this" value itself; in the "foo[i]->call_method()" case on
"foo[i]". We then adjust the exclusions in InvalidArg to consider operator->
on known-live things valid, to allow the thing that we were really trying to
accomplish with the "check for an operator call" bits:
"stackRefPtr->some_method()".
The test coverage being added for the made-up TArray type is meant to catch
things like the geolocation issue that was being hidden by the buggy behavior.
I'm not using nsTArray itself because some header included by nsTArray.h
tries to define operator new/delete bits inline and that triggers warnings that
then cause a clang-plugin test failure, because they're unexpected.
