Comment:

 `bug_16285_v4` (https://gitweb.torproject.org/user/gk/tor-
 browser.git/log/?h=bug_16285_v4) has three patches that adapt our code to
 the EME changes done between esr45 and esr52. The major change is that we
 don't have a switch for not compiling the code in in the first place
 anymore. Instead everything is bound to preferences now (even though
 `--disable-eme` is still available and should set the proper defaults).
