It's not entirely clear passing down all the metadata makes sense. On the
other hand, when creating the template execution sandbox, passing down
exports does assign the value for the exported variable in that execution
context. When that context is merged with the caller sandbox context, the
exported variable is reassigned, even if the value is not modified. Then,
if the caller sandbox itself reassigns the exported variable, it fails
because calling a template already did it once, unexpectedly.
Not passing down exported variables makes the template execution sandbox
never set those exported variables, so that they are not merged back. The
caller sandbox can then properly reassign the exported variable.
The in-tree Sphinx docs have been broken since bug 1041941 because
processing moz.build files outside their context doesn't work.
Specifically, templates aren't loaded (because this information usually
comes from a parent moz.build file). A new execution mode is needed.
I tried to implement a proper execution mode. However, I kept running
into walls. While we should strive for a proper execution mode, this can
be a follow-up, tracked in bug 1058359.
This patch implements extraction of Sphinx variables from ast walking.
It is extremely low-level and definitely a one-off. But it solves the
problem at hand: |mach build-docs| will work after this patch is
applied.

The reason to use '+' prefixing was to distinguish between options to the
mach command itself, and options that are passed down to whatever the
command does (like mach run passing down args to the built application).
That makes things unnecessarily awkward, and quite non-standard.
Instead, use standard '-' prefixing, and pass all the unknown arguments
down. If there is overlap between the known arguments and arguments supported
by the underlying tool (like -remote when using mach run), it is possible to
use '--' to mark all following arguments as being targetted at the underlying
tool.
For instance:
mach run -- -remote something
would run
firefox -remote something
while
mach run -remote something
would run
firefox something
As allow_all_arguments is redundant with the presence of a argparse.REMAINDER
CommandArgument, allow_all_arguments is removed. The only mach command with a
argparse.REMAINDER CommandArgument without allow_all_arguments was "mach dmd",
and it did so because it didn't want to use '+' prefixes.
These manifests are special in that they don't package their test files
into the test package. Each test listed in an instrumentation manifest
serves as an identifier rather than a file.

Up to now, DIRS and TEST_DIRS were dumb values. This change makes them
a list of ContextDerivedValues, and handles the fact that some types of
paths are relative to the current source directory and others to the
topsrcdir.
This also makes us one step closer to fixing bug 991983.
After bug 762358 mk_add_options MOZ_MAKE_FLAGS was simply ignored in client.mk
processing. At the same time, mach environment was expecting a list of options
while the mozconfig reader returned a single string, so straighten this up at
the same time.
