gecko-dev/toolkit/moz.configure
Gerald Squelart 3a965409ce Bug 1480331 - Compile and build JsonCpp without exception handling - r=glandium 
JsonCpp is used in different places around Firefox, which is normally built
without exception handling, so we don't want JsonCpp to `throw`.
Because we don't want to modify the JsonCpp files themselves (to ease future
update from the source), and some of its headers are directly included around
Firefox, we need to define `JSON_USE_EXCEPTION` to be 0 everywhere, which can
be done through moz.configure.
JsonCpp replaces its exception-triggering code with C asserts and aborts.

# WebDriver (HTTP / BiDi)
# ==============================================================
#
# WebDriver is a remote control interface that enables introspection and
# control of user agents. It provides a platform- and language-neutral wire
# protocol as a way for out-of-process programs to remotely instruct the
# behavior of web browsers.
#
# The Gecko implementation is backed by Marionette and Remote Agent.
# Both protocols are not really toolkit features, as much as Gecko engine
# features. But they are enabled based on the toolkit, so here it lives.
#
# Marionette remote protocol
# -----------------------------------------------------------
#
# Marionette is the Gecko remote protocol used for various remote control,
# automation, and testing purposes throughout Gecko-based applications like
# Firefox, Thunderbird, and any mobile browser built upon GeckoView.
#
# It also backs ../testing/geckodriver, which is Mozilla's WebDriver
# implementation.
#
# The source of Marionette lives in ../remote/marionette.
#
# For more information, see:
# https://firefox-source-docs.mozilla.org/testing/marionette/index.html
#
# Remote Agent (WebDriver BiDi / partial CDP)
# -----------------------------------------------------------
#
# The primary purpose is the implementation of the WebDriver BiDi specification.
# But it also complements the existing Firefox Developer Tools Remote Debugging
# Protocol (RDP) by implementing a subset of the Chrome DevTools Protocol (CDP).
#
# The source of Remote Agent lives in ../remote.
#
# For more information, see:
