Bug 1425906: Rename LINK to LINKER throughout the build system. r=glandium Windows linkers give special meaning to getenv("LINK"), which makes `export LINK=...` in mozconfigs do unexpected things.

 * IPC Transaction protocol for the WebAuthn DOM API. This IPC protocol allows
 * the content process to call to the parent to access hardware for
 * authentication registration and challenges. All transactions start in the
 * child process, and the parent replies with a "Confirm*" message, or a
 * "Cancel" message if there was an error (no hardware available, no registered
 * keys, etc) or interruption (another transaction was started in another
 * content process). Similarly, the content process can also request a cancel,
 * either triggered explicitly by the user/script or due to UI events like
 * selecting a different tab.
