Bug 1257823 - Move set_config() to the global scope. r=nalexander The way set_config is set currently makes it difficult to introspect moz.configure files to know what configuration items are being set, because they're hidden in the control flow of functions. This makes some of the moz.configure more convoluted, but this is why there are templates, and we can improve the recurring cases afterwards.

def DevToolsModules(*modules):
    '''Installs JS modules at a resource:// path that corresponds directly to
    their source tree location.

    For this to work as intended, a moz.build file should be placed in each
    source directory which uses this template to install only the JS files in
    its own directory.  Subdirectories should use their own moz.build.

    By following this pattern, there's less magic to require() and resource://
    paths, since they now match the source tree.

    Currently `DevToolsModules` can only be called once per moz.build, so we
    build a list manually above.  Bug 1198013 tracks fixing this to make it more
    like other moz.build constructs.'''
