Having not configured or out-of-date tools benefits nobody. It slows
people down.
Version control tools are an integral part of working on Firefox. It is
important for version control tools to be configured optimally and to be
continuously updated so they stay optimal.
The `mach mercurial-setup` command exists to optimally configure
Mercurial for working on Firefox and other Mozilla projects.
This commit adds a pre-dispatch handler to mach that will verify
Mercurial is in a happy state. If `mach mercurial-setup` has never
executed, it will complain. If `mach mercurial-setup` hasn't been
executed in the past 31 days, it will complain.
Yes, aborting command execution and forcing people to context switch to
run `mach mercurial-setup` is annoying. First, we have carved out
several exceptions to this behavior, including detection for running in
automation, on the machines of curmudgeons, when Mercurial isn't being
used, and from non-interactive processes. Second, I argue that people
ignore optional notifications and that having persistently
poorly-configured tools is worse than a single context switch at most
every month. Therefore, the heavyhanded approach is justified.
In addition, if we did support a non-fatal notification, we would
introduce the problem of extra output from commands. If anyone was e.g.
parsing mach output, we could very likely break those systems. These
cases should be caught by the isatty() check or be running in a context
with MOZ_AUTOMATION set. But you never know.

A subsequent commit will want to access the state directory path without
possibly creating it. Make that possible by extracting path resolution
to its own function.
We were de-referencing the checker variable after having moved it into
the array, which was causing a null pointer crash.
With this fixed, the plugin can be built with more recent versions of
clang.

Write a mozconfig fragment which makes the rust toolchain
provided by tooltool available for linux builds.
Use linux64 mozconfigs to enable rust for official builds of
that target. These aren't used outside of automation builds,
so including rust there will verify code on check-in without
requiring developers to install rust.
This removes ambiguity as to which modules are being imported, making
import slightly faster as Python doesn't need to test so many
directories for file presence.
All files should already be using absolute imports because mach command
modules aren't imported to the package they belong to: they instead
belong to the "mach" package. So relative imports shouldn't have been
used.
