This adds a new class which allows to create type safe resource handle
types. At the moment, the engine uses ints pretty much everywhere for
providing handles to resources created by the specific subsystems. Since
all ints are the same to the C/C++ typesystem it is perfectly legal to
pass a sound handle to the graphics API as a buffer handle which will
obviously cause issues.
This adds a new type called "ID" which is a wrapper class for a generic
handle but with added type safety. An instance of this class cannot be
passed to a function expecting another type of handle which provided
compile-time type safety for these APIs.
As an initial test I converted the game sound handles to this new type.
I already found a bug in the mainhall system thanks to this new type.
The mainhall used the game sound handles as sound instance handles which
probably meant that that specific code never really worked right. I
removed the code since there was no better alternative for fixing it.
This adds support for specifying multiple sounds for a single game sound
entry. The engine then selects which sound will be played based on the
strategy provided by the game data. This required a few changes to some
of the game code since previously every game sound had exactly one sound
file attached to it. The most notable change is that it is no longer
possible to determine the exact duration a sound can have so instead the
new code computes the maximum duration a sound can have and uses that
where appropriate.
This also adds support for randomizing the pitch and volume of the sound
to provide a more varied experience even if only a single sound is used.
One possible issue that exists is that the "sequential" strategy only
works globally at the moment so if two sources use the same game sound
concurrently then the two sources will share the sequence of sounds
since there is no sound instance data at the moment. That can be added
in a future change but should not present a huge issue for most
use-cases.
Visual Studio on Appveyor somehow causes deprecation error on _our_
definition of vsprintf. I have no idea why these changes introduced this
warning but I won't debug Visual Studio compiler bugs that I can't
reproduce with my Visual Studio version so I just disabled those
warnings.
It defaults to an empty string (resulting in no music) anyway, so there's no harm in it being missing, and the demo's mainhall.tbl doesn't contain these lines, so this change makes it possible to reach the mainhall with demo data.
cmission.main_hall defaults to an empty string, so calling main_hall_init() with an empty string is neither unsurprising nor uncommon. Since it's not actually caused by bad data, the warning can be considered actively harmful by training users that sometimes FSO just gives you a pointless warning.
The codebase had quite a few instances of .size() being called and then checked to see if it was 0 or not (or less than 1, or greater-than-or-equal-to 1, which are basically equivalent), when .empty() could be called instead (negated or not, depending on what the original condition was).
This allows to use standard TrueType Fonts for text rendering in FSO. It uses the NanoVG library which provides the ability of drawing 2D shapes. This library is used for most 2D operations now and can also be used directly by using the PathRenderer class.

Update comments
Remove support for the IPX protocol. The IPX selector button in the multi
options menu is now hidden, and the TCP button is disabled since there is no other option.
Left over pointer towards a structure that had been cleared and rebuilt could cause a crash. Found (and fix tested) by Axem. Also thanks to z64555 for bouncing ideas back and forth until this solution was found.

Adds two new mainhall.tbl options:
1) "+Misc anim over doors:" (misc anim rendered after doors)
2) "+Cheat String:" (exchanges misc anim when cheat is entered)

Also includes support for more than two mainhall resolutions, zooming
so one mainhall can adapt to multiple resolutions, setting new mainhall
fonts, help overlays for all resolutions and adjustable tooltip padding.
Also allows preload screens to be any resolution & aspect ratio.
