e599b86424 event/Loop: try to avoid the WakeFD when adding DeferredMonitor 
Add a flag that indicates whether the EventLoop is currently "busy".
As long as that flag is set, it does not need to be woken up - we can
simply add the DeferredMonitor to the list, and it will be caught by
EventLoop very soon.  This eliminates nearly all of the
DeferredMonitor overhead when compared to IdleMonitor, rendering
IdleMonitor mostly obsolete.

4c705334fa ClientList: use "delete" instead of Client::Close() 
Client::Close() installs a TimeoutMonitor, which is not something we

c9da3363a0 output/httpd: move all broadcast operations to the IOThread 
Add a Page queue to class HttpdOutput, and use DeferredMonitor to
flush this queue inside the IOThread.  This fixes a thread-safety
issue: much of EventLoop is not thread-safe, and the httpd plugin
ignored that problem.

19424e95db event/Loop: remove bogus "!quit" assertion 
Commit 1f11959 allowed modifying the "quit" attribute from any thread,
and thus the assertion may fail spuriously.  This assertion is too
strict for the relaxed use of "quit".  Let's remove it and move the
"quit" check to before the SockedMonitor::Dispatch() call.

1f1195975f event/Loop: non-recursive Break() implementation 
Simply set the "quit" flag and wake up the thread.  This works even if
we're inside this thread.  Setting "quit" to a new value without mutex
protection is usually not safe, but good enough here.

87fce8ef27 mixer/alsa: use DeferredMonitor to update file descriptors 
EventLoop::AddCall() and EventLoop::AddIdle() are unsafe, because we
can't cancel those calls.

d2a4f64fd6 event/BlockingCall: always use DeferredMonitor internally 
There is no advantage of using EventLoop::AddCall(), now that
DeferredMonitor is thread-safe.

a357d84dce event/DeferredMonitor: make fully thread-safe 
Instead of creating a new eventfd for each DeferredMonitor instance,
reuse EventLoop's eventfd, and add a std::list to EventLoop that
manages the list of pending DeferredMonitors.  This std::list is
protected by the same mutex as the "calls" list.

The bottom line is: reduced overhead because the per-instance eventfd
was eliminated, slightly added overhead due to Mutex usage (but
negligible), and we're thread-safe now.

This subsystem is now good enough to replace EventLoop::AddCall().
