54859e9f14 util/library: Allow loading of obs_module_t
Allows us to pass an obs_module_t into util::library::load() for cleaner code. This requires an additional flag so we don't unload a module that is still in use by libOBS.

5a3954ae0e project: Fix License, License headers and Copyright information
Fixes several files incorrectly stated a different license from the actual project, as well as the copyright headers included in all files. This change has no effect on the licensing terms, it should clear up a bit of confusion by contributors. Plus the files get a bit smaller, and we have less duplicated information across the entire project.

Overall the project is GPLv2 if not built with Qt, and GPLv3 if it is built with Qt. There are no parts licensed under a different license, all have been adapted from other compatible licenses into GPLv2 or GPLv3.

20e1a94eba util/threadpool: Initialize worker count to 0
Many platforms (and/or kernels) don't zero memory before it is acquired, resulting in uninitialized memory being used to store critical content. This made the threadpool assume it had an infinite number of threads to work with, despite actually having spawned none.

Fixes #1017

fddf21b8de util/threadpool: Optimize for dynamic thread pooling
While the previous approach of a static thread pool worked, it was sub-optimal in its resource usage. Many of the threads would never see a single task, and simply permanently sleep. This seems like a good idea, except that sleeping threads still end up in the scheduler, and thus waste a tiny amount of resources.

It is better to instead dynamically spawn threads when needed and only keeping the bare minimum around all the time. These dynamically spawned threads are also explicitly set to background priority which further reduces scheduling overhead. Finally optimizing the memory layout to prevent unwanted false sharing should also keep sporadic wake ups at a minimum.

This new model should be able to handle many more tasks than ever before, but is still not as optimal as it could be.

May need to find a better solution such as disabling all warnings on third party code.

6e1566386e project: Apply more C++ paradigms to the code
- Use auto in places where code clarity is improved or identical.
- Replace trivial constructors and destructors with default.
- Use true random for random generation.
- Use std::string_view where it is valid to do so.
- Apply const where it is valid to do so.
- Use references where it is valid to do so.
- Manually optimize memory usage with std::move and std::copy.
- Opt for memory efficient containers where the size is known ahead of time.

3eacc47085 util/logging: Don't reuse vargs (#632)
As vargs may be modified by some functions, we should not reuse it and instead create a copy of it. This fixes a segfault on logging calls happening with GCC, and potentially may fix other compilers and platforms as well.

f907fc80b0 updater: Add functionality to check for updates
Implements a manual and automatic update checker with support for both release and testing update channels, allowing users to stay as up to date as possible. It is fully compliant with privacy regulations around the world, as it stays completely silent and inactive until the user gives the Ok to connect to GitHub for the latest releases.

a39fd89ba7 util/library: Cross-platform handler for library loading
Adds a utility class and functions to load libraries and symbols from libraries somewhat safely. Libraries are immediately unloaded when the last reference to them is lost, so the shared_ptr should be stored if the library is actually needed.
