The function fluid_player_join in the library is broken beyond compare for the
usecases it was used for (see their #872). It does not wait until it is safe
to delete the player, so it is up to the end user to ensure that.
For OpenTTD we acquire a lock before fluid_synth_write_s16 and we acquire the
same lock in the stop function. So, only one of the functions can be doing its
thing, meaning we do not need to wait for the player to be stopped as it
cannot be doing anything as we prevent that by the lock.
Since pixel dimensions in SetPadding() are scaled by GUI size, padding for inset viewports was excessive.
Instead, automatically apply padding for WWT_INSET at widget level. This applies to all widgets inside a WWT_INSET, which in all instances is a NWID_VIEWPORT.
This meant that on opening the Multiplayer window, if you had more
than one server configured, it would one by one cancel all pending
queries and send a new. Result: only the last server was updated.
The most common case never needs access to it anymore. Make the
one exception to this explicit. This means the fact that we
store it is now an implementation detail.
If the highscore/news window panel size, which is now scaled by GUI zoom, is larger than the screen size, a loop will be entered where the window is repeatedly resized.
This is resolved by removing the minimal size from the panel, as the window is always resized to cover the screen anyway. This means the screen size can never be too small.

Hostnames like "content.openttd.org" resolve into multiple IPv4 and IPv6.
It is possible that either of the IPs is not working, either due to
a poorly configured OS (having IPv6 but no valid route), broken network
paths, or a service that is temporary unavailable.
Instead of trying the IPs one by one, waiting for a 3s timeout between
each, be a bit more like browsers, and stack attempts on top of each
other with slight delays. This is called Happy Eyebells.
Initially, try the first IPv6 address. If within 250ms there is no
connection yet, try the first IPv4 address. 250ms later, try the
second IPv6 address, etc, till all addresses are tried.
If any connection is created, abort all the other (pending) connections
and use the one that is created. If all fail 3s after the last connect(),
trigger a timeout for all.
