Gregory Szorc 5ddf815a31 Bug 1134072 - Support for sub-contexts; r=glandium
As content in moz.build files has grown, it has become clear that
storing everything in one global namespace (the "context") per moz.build
file will not scale. This approach (which is carried over from
Makefile.in patterns) limits our ability to do things like declare
multiple instances of things (like libraries) per file.

A few months ago, templates were introduced to moz.build files. These
started the process of introducing separate contexts / containers in
each moz.build file. But it stopped short of actually emitting multiple
contexts per container. Instead, results were merged with the main
context.

This patch takes sub-contexts to the next level.

Introduced is the "SubContext" class. It is a Context derived from
another context. SubContexts are special in that they are context
managers. With the context manager is entered, the SubContext becomes
the main context associated with the executing sandbox, temporarily
masking the existence of the main context. This means that UPPERCASE
variable accesses and writes will be handled by the active SubContext.
This allows SubContext instances to define different sets of variables.

When a SubContext is spawned, it is attached to the sandbox executing
it. The moz.build reader will now emit not only the main context, but
also every SubContext that was derived from it.

To aid with the creation and declaration of sub-contexts, we introduce
the SUBCONTEXTS variable. This variable holds a list of classes that
define sub-contexts.

Sub-contexts behave a lot like templates. Their class names becomes the
symbol name in the sandbox.

This directory contains common Python code.

The basic rule is that if Python code is cross-module (that's "module" in the
Mozilla meaning - as in "module ownership") and is MPL-compatible, it should
go here.

What should not go here:

* Python that is not MPL-compatible (see other-licenses/)
* Python that has good reason to remain close to its "owning" (Mozilla)
  module (e.g. it is only being consumed from there).
