This included adding the slugid 1.0.6 python source code in /python since slugid
is now a dependency of the ./mach taskcluster-graph command, as well us updating
references that used it. Previously the implementation was in-tree.
Previously, we used a PPA on Ubuntu to install Mercurial. The PPA has
proved to be unreliable. Furthermore, we didn't have a mechanism for
installing a modern Mercurial on Debian and other derived distros.
In this commit, we remove the PPA from Ubuntu. We add the ability to
install Mercurial from pip to the Debian bootstrapper. However, since
some people may not want <not apt> installing package-like things,
we add a prompt explaining the situation and giving users a choice.
We recommend installing a modern Mercurial via pip. But we also given
the option to install a likely legacy version via apt. And, for Git
users, we give the option to not install Mercurial at all.
Since the new version of the Ubuntu bootstrapper is empty, it doesn't
need to exist, so it has been removed.

Android version codes serve multiple masters. They indicate newer
versions, yes; but they also break ties between versions with
different features and requirements. High order bits effectively
partition the space of versions and are valuable. Since Android
version codes are signed Java integers, we have 31 bits to work with.
Mozilla's traditional build ID is YYYYMMDDhhmmss. This was chopped to
ten characters (YYYYMMDDhh, i.e., hourly build IDs) and then converted
to a decimal. This took many high order bits. We will lose another
high order bit in the 36th month of 2015 -- i.e., as soon as the year
rolls over to 2016. If we waited to lose the next higher order bit,
we'd lose that one in the 46th month of 2017 -- i.e., as soon as the
year rolls over to 2018.
The following patch sacrifices a high order bit to change the version
scheme, winning us roughly 15 years of hourly build IDs before we are
forced to lose another high order bit. So it's clearly to our
advantage to change the scheme sooner rather than later -- we will
sacrifice 1 bit for 15 years of build IDs, rather than keeping the
current scheme and sacrificing (say) 2 bits for 3 years of build IDs.
The resulting scheme produces build IDs that look like (in binary):
0111 1000 0010 tttt tttt tttt tttt txpg
The meaning of these build IDs is documented in the Python source code
that generates them.

The new variables are both passthru variables for now: in the future,

We have had singular ANDROID_ASSETS_DIR in Makefile.in for a while.
Fennec itself does not use the existing Makefile.in Android code, for
complicated historical reasons.
This makes the existing variable moz.build-only; generalizes the
existing variable to an ordered list; and adds the equivalent use of
the new list to the Fennec build, with a simple example asset.
This patch also updates the packager to include assets packed into the
gecko.ap_. Without the packager change, the assets/ directory in the
ap_ gets left out of the final apk. This whole approach is totally
non-standard but is more or less required to support our single-locale

It is useful to be able, during mozconfig execution, to do tests depending
on what was previously added with mk_add_options. Specifically, there is a
need to do this for MOZ_PGO because developers pushing to try may add it to
mozconfig.common.override.
While, ideally, it would be nice if we just defined the variable itself in
the mozconfig execution environment, that is a tedious task, having to jump
through hoops with eval, and handle all cases of variable assigment properly.
The hacky alternative is to just treat MOZ_PGO specially, but meh.
So instead, we set a ${var}_IS_SET variable to 1, indicating that a
mk_add_options defined ${var} to some value.
Bug 1153566 changed the regexp used in that method in such a way that there

That's a significant regression for a 4-character change.
But we can actually avoid using regexp in most cases, which can make things faster

I considered three ways to do this:
* one, as a Python script executed with $(shell);
* two, as a Python script that writes an include file for the preprocessor;
* three, as a function exposed to the moz.build sandbox.
I rejected two because it's both tied to the preprocessor, and awkward
to make handle the dependency on the buildid (in a file) and
additional build defines (in config.status).
I rejected three because I know of no precedent for this approach, and
it hides the dependency on the buildid.
One doesn't handle failures in the script gracefully, but neither did
the existing approach. This patch is at least testable.

Very much a first cut, but I'd like to get some Fennec early adopters testing.

Up to this point, mach command metadata has been stored in tuples.
Initially, things weren't so bad. But they have evolved into tuples with
many elements. Adding new attributes is cumbersome. Let's restructure
the code to capture metadata in a dedicated class.
Before, there existed a separate attribute on the @Command or
@SubCommand decorated method for each mach decorator: @Command,
@CommandArgument, @CommandArgumentGroup. With the magic of __ior__,
we can now capture all metadata on a single type. This simplies
processing, as we now only look at a single attribute on methods:
_mach_command.
Before, we used separate attributes to distinguish between mach commands
and mach sub-commands. Now that we have a type that can hold all data,
we combine things into the _mach_command attribute and look for the
presence of the "subcommand" attribute on this type to identify
sub-commands.

The moz.build reader uses absolute paths when referencing moz.build
files. *Finder classes expect paths to be relative to a base. When we
switched the reader to use *Finder instances for I/O, we simply provided
a default FileFinder based at the filesystem root. This was quick and
easy. Things worked.
Unfortunately, that solution isn't ideal because not all *Finder
instances can accept absolute paths like that. The
MercurialRevisionFinder is one of them.
Changing the moz.build reader to talk in terms of relative paths is a
lot of work. While this would be ideal, it is significantly easier to
defer the problem until later and hack up MercurialRevisionFinder to
accept absolute paths. This commit does exactly that.
Bug 1171069 has been filed to track converting BuildReader to relative

Now that moz.build files use finders for I/O, we can start reading
moz.build data from other sources.
Version control is essentially a filesystem. We implement a finder
that speaks to Mercurial to obtain file data. It is able to obtain
file data from a specific revision in the repository.
We use the hglib package (which uses the Mercurial command server) for
speaking with Mercurial. This adds overhead compared to consuming the
raw Mercurial APIs. However, it also avoids GPL side-effects of
importing Mercurial's Python modules.
Testing shows that performance is good but not great. A follow-up
commit will introduce a GPL licensed Mercurial finder. For now, get
the base functionality in place.

Sometimes moz.build data may not come from the local filesystem. To
support defining moz.build data in other backing stores, we switch
moz.build reading to use mozpack's *Finder classes for I/O.
The use of a FileFinder bound to / is sub-optimal. We should ideally
be creating a finder bound to topsrcdir. However, doing this would
require refactoring a lot of path handling in the reader, as that code
makes many assumptions that paths are absolute. This would be excellent
follow-up work.
While I was here, I cleaned up some linter warnings for unused imports.
On my machine, this commit results in a slight slowdown of moz.build
reading. Before, `mach build-backend` was consistently reporting 1.99s
for reading 2,572 moz.build files. After, it is consistently reporting
2.07s, an increase of 4%. This is likely due to a) function call
overhead b) the cost of instantiating a few thousand File instances
c) FileFinder performing an os.path.exists() before returning File
instances. I believe the regression is tolerable.

The current mode of execution of templates doesn't allow them to more advanced
control flow, like returning early, returning or yielding values, because that
mode of execution is equivalent to running the code at the top level of a .py
file.
Making the templates executed through a function call, although trickier,
allows those control flows, which will be useful for template as context
managers.
inspect.getsourcelines() and inspect.getfile() involve I/O out of our control.
Our use of those functions, however, doesn't require all their smarts. In fact,
we only use them on function objects, for which we can just do the work

Propagate that through to the Makefile backend and add a dependency
generated and an explicit rule to call $(RUSTC) to compile them.
rustc builds static libraries, not obj files. At least, if one
asks it to output an obj file, I'm not clear how to get all the
compiler-specific runtime libraries the code will expect to link
to. Therefore we generate a static library for each rust source
file (which must be a complete crate for the time being) and link
that. Because of the extension it ends up on the LIBS line in the
the corresponding .desc file.
Note that the static library does still depend on some system
libraries, e.g. -ldl -lpthread -lm on linux. Gecko already
links to all of those, so we don't keep track of it here.
Should we need to add explicit linkage for other targets,
rustc does print a list to stderr which can be parsed.
