The static local variable `enabled` in CooperativeSaveEnabled() is not
initialized until the first call to CooperativeSaveEnabled(), per the
C++14 standard, section 6.7 ("Declaration statement"), paragraph 4. This
initialization is thread-safe as of C++11, but it is *not* required to
be async-signal-safe. Use a namespace-scope variable instead, since this
is guaranteed to be zero-initialized before main() by section 3.6.2
("Initialization of non-local variables").
getenv() is technically not async-signal-safe either, hence the hedging
in the change summary line. However, glibc's implementation of getenv()
appears to be async-signal-safe in the absence of calls to setenv().

epoll_wait acquires EventPoll.listsMu (in EventPoll.ReadEvents) and
then calls Inotify.Readiness which tries to acquire Inotify.evMu.
getdents acquires Inotify.evMu (in Inotify.queueEvent) and then calls
readyCallback.Callback which tries to acquire EventPoll.listsMu.
The fix is to release Inotify.evMu before calling Queue.Notify. Queue
is thread-safe and doesn't require Inotify.evMu to be held.
Closes#121

This allows ValueOrDie() to be called on PosixErrorOr rvalues (e.g.
temporaries) holding move-only types without extraneous std::move()s.
