We should end the test once the OOM simulation has found the last allocation
it can instrument, not when the context is created. This exercises 3 extra
allocations (they may be in the DestroyContext).
Also:
* Print a + or a . to standard output to show if a context was
successfully created or not for each iteration.
* Rename this so all the OOM tests have OOM in their name.

Now that LCovRealm is allocated on demand, use a Vector directly instead
of allocating that vector on demand. To ensure pointer stability of
LCovSources, allocated them in the LifoAlloc and only store pointers in
the sources vector. They are still fully owned by the LCovRealm.

Save a little bit of memory when code coverage is not in use. Add a
collectCodeCoverage method to the realm so it can allocate LCovRealm on
demand. Also compute the realm name string from the constructor instead
of in the lookup code (this still happens at same time).

Avoid creating the ScriptNameMap in the off-thread parse zone. Instead
perform JSScript::initScriptName when merging the parse result to main
thread. This will avoid the need to migrate coverage initialization data
between Realms.

* At this point our DLL blocking infra is complicated enough that I decided to
bite the bullet and move all of this code out of `mozglue/build` and into its
own subdirectory, `mozglue/dllservices`.
* We delete the original `UntrustedDllsHandler` code which is now obsolete.
* We implement mozglue's `LoaderObserver`:
** When this observer registers itself with the launcher process API, it
receives a vector containing all saved records of loaded DLLs that happened
until that moment.
** This code handles profiler labels and stackwalking suppression.
** Once a load has completed, we either pass the load on to XUL for further
processing, or save it for later if XUL is not initialized yet.
* mozglue has its own `ModuleLoadFrame` implementation for the legacy blocklist.
* `DllServicesBase` is updated to support the new interfaces.
* We implement `FallbackLoaderAPI` for `plugin-container`, `xpcshell`, and
any other non-`firefox` processes that do not have a launcher process
providing a loader API.
* We add some wide to UTF8 conversion functions.

Split the GetCodeCoverageSummary API into a variant for a specific realm
vs checking all realms. This restores the original behaviour of the
getLcovInfo testing function to only return info on current realm. This
makes testing OOM behaviour much more predictable.

It was added in bug 1575760 and turns out to be causing a lot more
problems than anticipated.
However, the previous status quo is also not ideal, so we do
auto-generate .cargo/config.in instead, with a little trick that allows
to just copy it to .cargo/config instead of how individual scripts would
previously manually preprocess it.
