This is due to incorrect range checks in Instance::memCopy and
Instance::memFill. In particular, the checks inadvertantly succeed in the
wraparound cases where (uint32_t)(byteOffset + len) == 0, for the relevant
byteOffset and len pairings. This patch fixes the checks.

We can't remove navigator.javaEnabled() entirely because that would break any web content that tries to call the function.

This implements a new kind of lazy getter in XPCOMUtils that creates an object (implemented as a JS Proxy) that is resilient to be passed around as references to other functions, and will only evaluate the getter when it really needs to be used
Since URI hostnames are defined to be case-insensitive, we only ever see
lower-case hostnames when looking up substitutions. That means that
substitutions containing capital letters are inaccessible, which is a footgun
that has hit many people.
The handler should lower-case substitutions when they're added so that
look-ups are always case-insensitive.

We out-of-line the relevant functions because assertions can generate
quite a bit of code, and we'd rather let the compiler determine if these
functions should be inlined now.
Our normal ubuntu 16.04 test image is suitable for hosting an Android x86
emulator with these minor updates: Install kvm and make sure /dev/kvm
rw permissions are open for everyone. Note that /dev/kvm is generally
only visible when running docker with --privileged; its permissions
cannot be modified in the Dockerfile, only at run-time: run-task is the
first opportunity.

The tests pass in automation, however, because automation always defines
the rules for buildid.h and source-repo.h in the toplevel Makefile.in.
For local builds, however, those rules are not defined to avoid build
churn. Let's ensure that the necessary rules are defined during testing
as well.
The build system knows at build-backend time where to find each IDL
file; making xpidl-process.py rediscover this by requiring
xpidl-process.py to search through directories to find input IDL files
is silly. To rememdy this, we're going to modify things so full paths
are passed into the script. Those paths can then be used directly, with
no searching.
The tail end of the xpidl Makefile.in contains a line, generated for
every xpt file:
$(1): $(addsuffix .idl,$(addprefix $(dist_idl_dir)/,$($(basename $(notdir $(1)))_deps)))
This line, in context, is saying that the xpt file depends on all of its
input IDL files. But xpidl-process.py already generates this
information when we pass it --depsdir, which we do. So this code is
redundant with what we already generate, and it can be removed.
The previous patch required us to pass a single -I argument pointing at
$(DIST)/idl so IDL include statements would work correctly. This patch
lifts that limitation and explicitly points xpidl-process.py at the
locations of all the IDL source directories to search for included IDL
files. Invocations of xpidl-process.py no longer depend on IDL files
being copied to the objdir.
Building on the last patch, we can change the build process to pass in
the directories where the input IDL files can be found. It is
convenient to pass in just the relative source directory paths, to
encourage people to not look in the object directory and to make the
command lines slightly shorter.
xpidl-process.py still assumes that included IDL files can be found by
looking in a single directory. We add a single -I argument to the
invocation of xpidl-process.py to accommodate this short-sightedness.
The current IDL build setup assumes that all IDL files can be found in a
single directory. This setup requires that all IDL files be copied to a
single directory, which is suboptimal in terms of disk I/O and also
complicates things like generating IDL files at build time.
As a first step in moving away from this state of affairs,
xpidl-process.py needs to be taught that the input IDL files could
potentially be found in multiple directories. The current setup can
just specify $(DIST)/idl as the lone directory to examine. Future
patches will change this to examine multiple directories.
This method is only called in one place, and it doesn't pass
allow_existing. Whatever ugly thing this keyword was working around
doesn't exist anymore, so let's get rid of it.
