935e622915 event/Loop: allow calling AddFD()... before starting the EventThread
Relax the assertions.  This is necessary if BlockingCall() is used
before the thread is started.

replace assert.h with cassert
The former was deprecated with C++14.

According to the C++11 and C++17 standards, both files are identical.

6c67408944 event/Loop: add flag alive
This replaces the old `dead` flag which was unreliable; it was `false`
if the EventThread was not yet started, which could cause deadlocks in
BlockingCall().

ce49d99c2f check.h: remove obsolete header
Since we switched from autotools to Meson in commit
94592c1406, we don't need to include
`config.h` early to properly enable large file support.  Meson passes
the required macros on the compiler command line instead of defining
them in `config.h`.

This means we can include `config.h` at any time, whenever we want to
check its macros, and there are no ordering constraints.

a1309a90ac event/Loop: use boost::intrusive::list to store IdleMonitors and DeferredMonitors
The intrusive contains can easily erase items without searching
through the whole list.  This removes a good amount of runtime
overhead.

Add the debug-only flag "virgin" which gets checked by assert()
calls.  Fixes assertion failures when using zeroconf/avahi.

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.

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().

46bab7e4b9 Add infrastructure for using multiple event loops
This change adds two configuration options:

  --with-eventloop=[glib|internal|auto]
  --with-pollmethod=[epoll|auto]

First allows switching between GLib event loop and internal one.
Second chooses backend to use for internal event loop.
Conditional compilation symbols are changed accordingly.
Additional helper macro MPD_OPTIONAL_FUNC_NODEF is added as well.
