This is a large patch which tries to switch many of the external consumers of
nsGlobalWindow to instead use the new Inner or Outer variants.

As a result of this patch, the hash algorithm used in add-on signature
verification will come from the PKCS#7 signature. If SHA-256 is present, it will
be used. SHA-1 is used as a fallback. Otherwise, the signature is invalid.
This means that, for example, if the PKCS#7 signature only has SHA-1 but there
are SHA-256 hashes in the signature file and/or manifest file, only the SHA-1
hashes in the signature file and manifest file will be used, if they are present
(and verification will fail if they are not present). Similarly, if the PKCS#7
signature has SHA-256, there must be SHA-256 hashes in the signature file and
manifest file (even if SHA-1 is also present in the PKCS#7 signature).

The crash reports for this section of code suggest that in some cases, we're
ending up with a null Omnijar archive when trying to pre-load files. Since the
pre-load file list is determined in the previous session, and the startup
cache (where the pre-load list is stored) is cleared whenever the build ID
changes, it should never be possible for the given omnijar archive to be
missing here.
These crashes also tend to appear in conjunction with crashes due to failures
in the GetSharedGlobal function, and may have a similar cause.
This change adds better diagnostic information to these crashes, and should at
least tell us which omnijar archive we're failing to get, and the archive path
that caused us to load that archive. It may not tell us much, but it may point
to data corruption, or provide some other clues.

Since we don't currently know where or how loading the service is failing, we
need logging in two places:
1) In ServiceWorkerRegistrar, which will tell us about any JS errors that
occur in the factory constructor.
2) In the XPConnect module loader, which will tell us about any JS errors
which happen while loading the top-level module script.
If the load fails due to a non-JS error, we'll simply get a nsresult failure
code, which well be less informative, but will still tell us something about
the failure mode.

Right now, NS_GENERIC_FACTORY_SINGLETON_CONSTRUCTOR expects singleton
constructors to return already-addrefed raw pointers, and while it accepts
constructors that return already_AddRefed, most existing don't do so.
Meanwhile, the convention elsewhere is that a raw pointer return value is
owned by the callee, and that the caller needs to addref it if it wants to
keep its own reference to it.
The difference in convention makes it easy to leak (I've definitely caused
more than one shutdown leak this way), so it would be better if we required
the singleton getters to return an explicit already_AddRefed, which would
behave the same for all callers.
This also cleans up several singleton constructors that left a dangling
pointer to their singletons when their initialization methods failed, when
they released their references without clearing their global raw pointers.

mozJSComponentLoader is created using XPCOM. However, you can only
call it once or it'll crash. This patch fixes that by using a
singleton macro.

It's easy to mess up the scoping so that (a) the label is pushed and then
immediately popped, and/or (b) the string doesn't live long enough. It's also
easy to do a utf16-to-utf8 conversion unnecessarily when the profiler is
inactive. This patch splits that macro into three new ones that are harder to
mess up.
- AUTO_PROFILER_LABEL_DYNAMIC_CSTR: same as current.
- AUTO_PROFILER_LABEL_DYNAMIC_NSCSTRING: for nsCStrings.
- AUTO_PROFILER_LABEL_DYNAMIC_LOSSY_NSSTRING: for nsStrings.

This change requires introducing nsID::Clone(). Because it's infallible, the
patch also removes some redundant failure-handling code. (nsMemory::Clone() is
also infallible, so this code was redundant even before this change.)

The new code is slightly less efficient because it requires measuring the
string length, but these strings are all short so it shouldn't matter.
Note that the case in DataToString() is a little different. The std::min() that
was there appears to be excessive caution -- this code is always printf'ing
some kind of number, so 32 chars should never be reached -- but it was bogus
anyway, because if 32 was exceeded then (a) we would have overflowed `buf`, and
(b) we'd be returning a non-null-terminated string.

They are equivalent -- both infallible, both requiring measuring the length of
the string -- but moz_xstrdup is much more readable. (One place deals with
16-bit strings and so uses NS_strdup instead, which is also infallible.)
The patch also removes some failure-path code that will never execute due to
the infallibility.
