After the previous patches, we no longer rely on the component manager
to incidentally start up XPConnect when we load the JS loader service
or to hold the JS component loader alive, so the do_GetService() call
for the JS loader in XPCOMInit.cpp can be removed. After that is done,
the JS loader is no longer used as an XPCOM component, so all of the
boilerplate for that can be removed.

nsLayoutModule must be initialized in order to call into JS, but I
don't want to have to rely on calling a service in that
module. Instead, always initialize the module very early in component
manager initialization. This also makes initialization more
consistent, so things like errors in manifests won't affect when it
happens, which can result in different behavior in different builds.
I also made nsLayoutModule initialization infallible, because I can't
imagine that we can do much that is useful without it.
Another change I made is that gInitialized is set to true even in a
GPU process. This simplifies checking whether initialization has
happened already when we start up the layout module.

JS is the only file extension actually supported, and there are a few
layers of cruft that can be eliminated if we specialize it.
This eliminates one XPCOM registration of the JS component loader.

clang can handle MSVC-like codepaths generally, so we want to use those
when building with clang for Windows. So we switch _MSC_VER over to _WIN32
to pick up those codepaths when compiling for Windows with clang.
Additionally, we relax the ordering of sections for the same scenario.
Note that we do need to tell clang to use -fms-extensions with the MSVC code,
we do that in the mingw clang build job patch.

Nearly all of the consumers of category enumerators require the entry value,
either along with or instead of the name. Including both by default simplifies
things considerably for most consumers, and allows us to remove the XPCOMUtils
wrapper that JS callers typically use to enumerate category entries.

In order to allow JS callers to use nsISimpleEnumerator instances with the JS
iteration protocol, we'll need to additional methods to every instance. Since
we currently have a large number of unrelated implementations, it would be
best if they could share the same implementation for the JS portion of the
protocol.
This patch adds a stub nsSimpleEnumerator base class, and updates all existing
implementations to inherit from it. A follow-up will add a new base interface
to this class, and implement the additional functionality required for JS
iteration.

This assertion was always meant to be a best-effort thing to catch obvious
errors, but the cases where the assumptions it makes fail have been growing. I
could remove it entirely, but I'd be happier keeping at least some basic
sanity checks.
This compromise continues allowing any address below the first argument
pointer, and extends the assertion to also allow anything more than 2KiB above
it. We could probably get away with stretching that to at least 4KiB, but 2
seems safer, and likely enough to catch the obvious cases.

Much like the component manager, many of the strings that we use for category
manager entries are statically allocated. There's no need to duplicate these
strings.
This patch changes the category manager APIs to take nsACStrings rather than
raw pointers, and to pass literal nsCStrings when we know we have a literal
string to begin with. When adding the category entry, it then skips making
copies of any strings with the LITERAL flag.

Our factory registrations already require that we store nsID pointers, which
we generally handle by using pointers to static data, or arena allocating a
copy of a dynamic ID.
Since we already have viable pointers to these IDs, there's no reason to store
an entire second copy for our hash key. We can use the pointer, instead, which
saves 16 bytes per entry.

Most of our components are static, and registered using literal C strings. For
those components, we currently use a nsDependentCString as a key when creating
a hash entry, which leads to an unnecessary duplication. Using literal
CStrings instead avoids the duplication.
