Properly add SDL mocks for macOS.

Use library in new subproject.

Define separate package for config code.

Ensure log directory base path is relative to the executable.

Separate MIDI utils into its own package.

Extract tests from source directory.

Add second character.

Remove old SDL dependency.

Put minIni, and bdd-for-c dependencies to subprojects dir.

Extract additional platform-specific imports to basic compatibility
header.

Server runs ok, the game runs but with no window...

Ensure input test implementation is aligned to current input API.

Unify variables across the project.

Add correct includes.

Separate mock library from source.

Put mocks to directory structure mimicking project structure.

Use abstraction instead of using SDL dependencies.

Use CMake definitions to specify config paths and filenames.

Instead of using macros, use iterators built-in on each list for
filtering and traversing.

Provide support for XInput mappings.

Demonstrate on-the-fly flip for sprites.

Make distinctions between internal and external (downloaded from
third-party servers).

The sprites are now loaded using a utility function in IZ_video.

The magazines for each weapon except the rifles have been drawn.

Add templates for config item types.

Also updated server's config to use the global config module.

Remove symlinks and make codebase use common modules instead.

Rename files in order to prepare for extraction for publishing
subsystems independently.

Make sure to have help messages for both the game and the server.

This file is unnecessary.

Put input and video subsystems into their own directories.

Split the network events to the net directory to keep the app code
implementation clean.

Database will be used for authentication.

Implement the sending of input events to the websocket server.

Update identifiers to be consistent.

Add subdirectories for grouping net-related functions.

Make server optionally have a mountpoint for putting assets.

Connect client to server, save connection details.

Attempt to connect client to server.

Isolate network logic to each subsystem.

Split callback logic into several functions.

Update initialization method.

Use ring example.

Use minimal server echo example instead.
