7c47fe746c event/Loop: AbandonFD() unlinks the SocketEvent 
Fixes use-after-free bugs causing assertion failures at shutdown,
because all "abandoned" SocketEvents are still in the linked list.

38dab040b3 event/Loop: add compile-time option to disable multithreading 
Not for MPD, but for other applications which might want to copy its
event loop, but do not need multi-threading.

1686f4e857 event/IdleMonitor: refactor to IdleEvent 
Instead of using this as a base class implementing a virtual method,
the new class IdleEvent can be used as a variable, decoupling
IdleMonitor's internal state from the derived class.

This is similar to commit 30a5dd267b
which refactored TimeoutMonitor to TimerEvent.

41bc17a27f event/SocketMonitor: add ready_flags 
By making each SocketMonitor keep track of its ready flags, this
removes a lot of overhead from EventLoop::RemoveFD().

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.

remove gcc_unused 
[[maybe_unused]] (introduced in C++17) is standard C++.

https://clang.llvm.org/docs/AttributeReference.html#maybe-unused-unused
says that this is equivalent to the GNU unused attribute.

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.
