The test broke in 52e6fce3e6f6. The fix is to:

a) ensure the baz.def file exists
b) change the checked path in the backend.mk file

DEFFILE is currently just used as a passthrough variable. All but one of
the current uses of it use `SRCDIR + '/file.def'` to get a srcdir-relative
path anyway, and the other one wants an objdir-relative path, so using
Path makes everything clearer.

This makes it more straightforward to translate the paths for the WSL
build.

Currently line linters (linters that open a file and process it line by line,
by applying a regex for example), don't handle directories. If a directory is
passed in, it will try to 'open' it, which fails. Directories can get hit  if
the linter has a directory in its include directive or if the user passes in
--no-filter.

This patch modifies LineLinters so that if a directory is detected, we search
for all relevant files under that directory. If 'extensions' is used, we'll
look for only files with appropriate extensions. Otherwise we assume the
linter wants every file.

The MozillaBuildBootstrapper specific rust install code in not needed as
mozbase already includes genertic code to achieve the same outcome. The
mozilla-build specific code also leads to issues where it tries to add already
existing targets and fails the bootstrap. This changeset removes the
mozilla-build specific step.

The `js` crate at `js/rust` depends on the `mozjs_sys` crate at `js/src`, so it
makes sense to make it the top level crate.

To construct an empty set, we need to use the `set()` notation. In order
to do that, we need to expose `set` to the moz.build sandbox.

manager for Repository. It no-ops by default. On HgRepository it
controls the lifetime of the persistent hg process.

A helper method for running an hg command via hglib has been added.
We can't transition existing methods to hglib because hglib
requires a context manager, which no consumer is using yet.

These tests weren't running in automation because hglib wasn't
available. An upcoming commit will vendor hglib. This exposed that the
tests can fail if ui.username isn't set.

In this commit, we introduce a helper function to obtain an hglib
client with ui.username set. We also convert tests to use the context
manager form of the client so resources are cleaned up immediately
without relying on refcounting or garbage collection.

Bug 1390393 - Override tooltool files with toolchain artifacts when one is given to `mach artifact toolchain`. r=gps

When the tooltool manifest contains e.g. clang.tar.bz2 and it's also
provided by some toolchain job artifact, we still download both. In
fact, depending how things go, the tooltool one could take precedence.

In practice, this hasn't caused problems so far because we've removed
tooltool manifest items early on, and when we didn't, it was still the
same version as provided by toolchain jobs.

It is still necessary to fix for the future, though.
