This patch contains two backports for reproducibility issues found and
fixed in LLVM's optimization code.

The patch from bug 42574 might not be necessary in our context as I only
witnessed problems when compiling Stylo with an older Rust (1.32.0) and
then omptimizing with LLVM 8. However, it's hard to exclude any
mismatching builds we encountered so far from being affected by that
issue, so I think it is safer to backport that patch as well.

Bug 43909 is an issue we and Mozilla definitely hit and very likely
responsible for at least the vast majority of different builds we got
over the course of the last weeks and months. Many thanks to Alex
Crichton for the invaluable help in tracking this issue down.

If the linux64 mar-tools is not available, use any of the other
mar-tools that is available.

This will significantly improve the quality of life of Tails release managers
and developers. Thanks to boklm for the help!

The default bridge CDF2E852BF539B82BD10E27E9115A31734E378C2 has both an
IPv4 and IPv6 address but it is no longer reachable over it's IPv6
address, so it's time to remove it.

Versions bump and Changelog update

We update rbm for bug 27265: fix output_dir value in sub-projects.

As part of this fix, the patch in rbm is changing how the value of
output_dir is overriden by rbm when handling input_files: the output_dir
option is now defined under norec, which has priority over normal
options but is not inherided in sub-projects. In rbm.conf we are also
changing the output_dir option in var/build_id_txt so that the build ids
do not depend on the path on the current system. Because of the change
in rbm we now need to reset `norec` so that our value of `output_dir` is
correctly taken into account.

This commit fixes <https://bugs.torproject.org/32606>.

We will start supporting updates in the nightly channel only for a
limited set of locales.

Previously we used "default" as the channel name for nightly builds,
which is the channel name intended for local builds. We are now
switching to "nightly" as the channel name.

Include the current day in the nightly version number, so that each
build gets a different version number.

We get this version number using a perl function, and a "state"
variable, so that the day when the build was started is used.
This avoids issues when a build is started on a day but finishs on a
different day.

In the nightly directory, the builds are now stored using the version
instead of just the date.

We also allow overriding this version number by using the
TORBROWSER_NIGHTLY_VERSION environment variable. This could be useful
for example if you need to generate incremental mars for the version
from the previous day.
