There are now only a handful of buildbot jobs remaining and the concern over
outdated treeherder exclusion profiles has largely been resolved.
This does remove the tc() group from a substantial number of tasks which will
now show up as top level tasks, potentially adding clutter. In some cases, we
might want to re-add a new group (e.g group builds or compiled tests together).
However rather than try to predict the best group names for tasks I'm unfamiliar
with, I think it's best to land this as is. Then if things are looking too
cluttered at the root namespace, file follow-up bugs as needed.

In bug 749312, we were given permission to create a source readme
instead of a source tarball. This will save us cycles, disk, and
human configuration time.
We still need to address the missing balrog_props.json for
beetmover-source for that task to turn green.

Land date changes to support windows nightlies onto central
Supports beetmoving from the build-signing task, as well as ignoring dependencies if we have nothing to beetmove in them (e.g. build-signing for OSX)

Several years ago there was a single zip file for all test files. Clients
would only extract the files they needed. Thus, zip was a reasonable
archive format because it allowed direct access to members without
having to decompress the entirety of the stream.
We have since split up that monolithic archive into separate,
domain-specific archives. e.g. 1 archive for mochitests and one
for xpcshell tests. This drastically cut down on network I/O
required on testers because they only fetched archives/data that
was relevant. It also enabled parallel generation of test archives,
we shaved dozens of seconds off builds due to compression being
a long pole.
Despite the architectural changes to test archive management, we
still used zip files. This is not ideal because we no longer access
specific files in test archives and thus don't care about single/partial
member access performance.
This commit implements support for generating tar.gz test archives.
And it switches the web-platform archive to a tar.gz file.
The performance implications for archive generation are significant:
before: 48,321,250 bytes; 6.05s
after: 31,844,267 bytes; 4.57s
The size is reduced because we have a single compression context
so data from 1 file can benefit compression in a subsequent file.
CPU usage is reduced because the compressor has to work less with
1 context than it does with N. While I didn't measure it, decompression
performance should also be improved for the same reasons. And of course
network I/O will be reduced.
mozharness consumers use a generic method for handling unarchiving.
This method automagically handles multiple file extensions. So as long
as downstream consumers aren't hard coding ".zip" this change should
"just work."

Add configurations for building and uploading AArch64 Nightly builds, in
tier 1 and without artifact support for now.
As for not denoting AArch64 builds as "api-21", I don't really think we
will split AArch64 the way we split ARMv7 before. Originally, we split
into API 9 and API 11+ because of lots of "constrained" devices that
were stuck with API 9. We made an API 9 APK in order to lower our
footprint on those devices. That probably will not be a problem for
AArch64, because devices with API 21+ and AArch64 support are usually
more than capable for running Fennec. Secondly, it was a big change for
Android going from API 9 to API 11+, so we saved quite a bit of
code/resources when we stripped out API 11+. I don't see such drastic
changes going from API 21 to upcoming versions, so even if we did split,
I don't think it'll get us much benefit.

This is a more robust approach than using substring matching on task labels.
As an optimization, this simply avoids creating balrog tasks for unsigned beets
using only-for-attributes, rather than omitting them in a transform.
