It's been more than two weeks since the 1.23 stable release, and
we're making official builds with that toolchain release, so begin
requiring that version so new language features can be used in
development.

We add a wrapper for llvm-dsymutil for macosx CI builds such that when
it crashes, we attempt to get a reduced test case and upload it as a
build artifact. This will allow to more easily report such crashes
upstream.

By default, wget prints dots every 1k bytes. This can render a
lot of output for large files. We switch to the "mega" style, which
makes each dot represent 64k, thus reducing output by up to 64x.
We also force the use of dot display. By default, it uses "bar"
which attempts to use terminal formatting if possible. Since most
of this code executes in CI and terminal control characters can
interfere with logged output, we force the use of "dot." (Although
wget appears to automatically switch to dot in TC today. But
consistency is good.)

There were a few constraints in the choice of the version of dpkg to
backport:
- 1.17.20 is the first version that supports the debian source format
for that xz-utils package.
- versions >= 1.17.10 and <= 1.17.22 fail to build on wheezy.
- versions >= 1.17.21 depend on a version of patch not available on
wheezy.
All in all, the simpler choice was to go with version 1.17.20 with a
backport of the build failure fix.
That version of dpkg breaks the version of devscripts in wheezy, so the
version from wheezy-backports would be better to use, but we can't
unconditionally use it on all builds, because it happens that
mk-build-deps from that version is broken with the dpkg in wheezy.
In the end, it's simpler to build that backport and rely on package task
dependencies rather than selectively install the package from
wheezy-backports, so we do that. Except we can't use version
2.14.11~bpo70+1 because of bug 1419577.

In many cases, building docker images starts on machines that don't have
a cached checkout, and it often takes forever to get a full clone. It
used to be worsened when 3 jobs could run at the same time because the
worker would start up clean, and 3 jobs would be doing a mercurial clone
at the same time, thrashing I/O, but that part is fortunately fixed.
It is still, however, appreciable not to waste time in the mercurial
clone part of image creation.

The one available in Debian wheezy is 3.81, but we're explicitly using

Switching to Debian build images will force a version bump from
pulseaudio 0.9.something to pulseaudio 2.0. Practically speaking, as
long as bug 1427150 is fixed (which it is), this is strictly better,
because this enables all the PA_CHECK_VERSION(2,0,0) code in libcubeb,
which handles port availability (whether output is plugged or not), and
with bug 1427150, it does so in a backward compatible manner.
Now, since this is a behavior change from what we're currently shipping,
this has the potential of triggering unexpected test failures, or break
sound for users. The likelyhood of the latter happening is rather low,
though, because Linux distros have been building with pulseaudio >= 2.0
for a long time and we haven't heard about port availability breaking
sound for them. But it's still better to decouple this change from the
switch to Debian.
We abuse the build-gtk3.sh script which installs gtk3 in the CentOS
build image to install pulseaudio as well.

The one available in Debian wheezy is 1.7.10.4, which is really old, and
on our centos images, we're using 2.8.0rc3, which, while old too, is
more modern. While we may want to go with a more recent version, I'd
rather avoid differing from what we currently use, so use the exact same
version.

One of the last remaining differences when building Firefox on Debian
with all the changes we've done so far is that linking against the
system libc statically links some CRT objects. This causes massive
differences in the resulting binaries because of slight differences
in those objects (because they weren't compiled with the same compiler
and because they're not for the exact same glibc version)
In practice, their content difference don't cause any problem. If they
did, we wouldn't be able to run our builds on newer systems than those
we build them on. The only hypothetical risk would be to run on systems
with a glibc older than Debian 7's, but those already can't run Firefox
anyways (those systems don't have Gtk+3, which is a system requirement).
AFAICT, this is only an hypothetical problem anyways, even such systems
with Gtk+3 should be able to run those builds. Plus, this is a change
that will happen anyways when switching to Debian-based build images,
since they would be using the CRT objects from there. We're merely
making it happen earlier so that the differences from switching to
Debian-based build images are more tractable.
Note we only do this when building GCC on Debian, allowing to roll back
to CentOS-based toolchains by just switching back the toolchain jobs to
use the desktop-build docker image again.
When building on Debian (which we now are), this means we enable
.init_array/.fini_array.
When building on CentOS, this means no change. Which implies we could
roll back to CentOS-based toolchains by just switching back the
toolchain jobs to use the desktop-build docker image again.
This change causes massive differences in the resulting binaries because
of the offset differences, but practically speaking, there is no
difference. .init_array/.fini_array have been supported in glibc for 18
years.
We believe this is another spurious memcheck error triggered
by code from Rust 1.23.0. See also bug 1394696.
For some reason, this error occurs both with and without
the leading underscore on mangled std::sync::once methods,
so this change matches either with a wildcard.

The Python version validation in virtualenv.py is only called in 2
locations: `python -m mozbuild.virtualenv` and in moz.configure.
I believe that nobody calls `python -m mozbuild.virtualenv` any more.
That means that moz.configure is the only caller of
verify_python_version(). That means we can inline the logic into
moz.configure.
It makes sense for version checking to live in moz.configure because
the role of moz.configure is to evaluate the sanity of the environment.
So this commit does just that.

The system binutils and gcc are built with that option on Debian, but
not on CentOS. That makes no practical difference, except for the fact
that when building GCC, we use our own-built binutils (as per bug
1427316), but use the system GCC. And a GCC built with --with-sysroot=/
doesn't work with a binutils built without. However, a GCC built without
--with-sysroot=/ works fine with a binutils built with it. So this
change is compatible with building our GCC on both CentOS and Debian.
We currently use a 32-bit Rust toolchain for win32 builds, but this can lead
to OOM situations. This patch makes win32 builds use a 64-bit Rust toolchain,
which requires a little bit of extra configuration because rustc needs to
be able to find a link.exe that produces 64-bit binaries for building
things like build scripts, which are host binaries.
We will now generate a batch file that sets LIB to the paths to 64-bit
libraries and invokes the x64-targeting link.exe, and add a section to the
.cargo/config file to instruct cargo to use that batch file as the linker
when producing 64-bit binaries.

mk_add_options has this kind of awkward feature where
mk_add_options VAR=value
would set VAR for the build through client.mk, but not when running
make -C objdir target. But
mk_add_options "export VAR=value"
does.
We might want to change that on the long run, but the side effects would
have to be calculated first.
OTOH, we have automation jobs that run compilations during `make check`
(e.g. rusttests), which is not invoked through client.mk. So they
currently don't get the same PATH as the build part, meaning that
they're using system binutils instead of the one from the GCC toolchain
package.

I was able to reproduce the failure to apply llvm-dsymutil on the last
mozilla-central revision before debug info was temporarily disabled for
rust, and validated that the problem was gone in clang 4.
After some bisection, r289565 was identified as having fixed the
problem, which, reading the commit message, makes sense.
It was however not possible to simply cherry-pick, because of multiple
code changes between 3.9 and 4. However, apart from the volume of
conflicting changes, it was more or less straightforward to backport.
Interestingly, the patch for r313872 was relying on changes from
r289565, which is why it required a variant specifically for 3.9, but
now we can use the same patch as for other versions. Well, except
there's a small difference in the context, and build-clang.py doesn't
allow fuzz, so we manually edit the patch to remove that line from the
context.

In bug 1426785, Gtk+3 build was moved to docker image creation time, and
at the same time, the removal of .la files was stripped, because it
seemed too broad to do that in /usr/local/lib*, and because I didn't
really remember why it was there in the first place.
I now do remember, and that's because libtool likes to add useless
dependencies on libraries just because direct dependencies transitively
depend on them. For example, this adds a dependency on libffi to
libpangocairo, which doesn't use it directly.
I also happens that /usr/local/lib* is empty at the moment we build
gtk3, so we can just do the cleanup there.
On its own, this change is useless, but:
- it restores the libraries in their state pre-bug 1426785,
- it helps reduce some differences when building on Debian (for bug
1399679), easing the comparison of those builds.
