Let cmake know that we're cross-crompiling.

Prepare to add some code around the _build() call.

Eliminate conflict with other Project classes.

Allow DeferredEvents to call EventLoop::Break().

emplace already calls std::pair. No need for it again.

No need to emplace when calling std::make_shared.

make_pair is an old C++98 function that can be replaced by modern
shorter constructs.

NB: Check the sysconfdir setting to determine where mpd will look for mpd.conf; if you expect mpd to look for /etc/mpd.conf the sysconfdir must be '/etc' (i.e., not 'etc' which will result in mpd looking for /usr/local/etc/mpd.conf):
 
.. code-block:: none
 
 meson configure output/release |grep sysconfdir

If this is not /etc (or another path you wish to specify):

.. code-block:: none

 $ meson configure output/release -Dsysconfdir='/etc' ; meson configure output/release |grep syscon
  sysconfdir              /etc                                               Sysconf data directory

This eliminates all but one DeleteLocalRef() call.

Include the most specific header documented by MSDN instead.

These should be equivalent anyway.

The ChainFilter class is extremely complicated code, and will grow to
be even more complicated when the Filter interface gets extended.
Let's just remove it; we can easily chain many TwoFilters instead.
