sockets: Make fd member variable protected

audio_renderer: Make GetCommandBuffer() take a u32

audio_manager: Minor cleanup related changes

Other things shouldn't be able to directly mess around with the
descriptor

This function is only ever called with unsigned types, and all of the
other interface functions take session_id as a u32, so this makes the
class a little more consistent.

Moves the include into the cpp file to lessen header dependencies.

We can just use a local here to get rid of a second cast.

Prevents unnecessary reallocations in the event the captured variables
are larger than the internal std::function buffer.

Allows us to get rid of some unnecessary forward declarations and
includes.

This isn't used, so it can be removed.

This isn't used by the class, so this can be removed for the time being.

astc: Enable parallel CPU astc decoding

core: implement HwOpus GetWorkBufferSizeForMultiStreamEx

core: nfp: Implement amiibo encryption

[Coretiming/NVNFlinger] Improve multi-core vsync timing, and core timing accuracy

audio_core: Mark several member functions as const

GIT: Modify .gitignore to ignore wildcard for build directories

UI: move icons from default into colorful theme.

Helps if you have multiple build folders. There are other, dark ways to
hide extra build folders from git, but this is better.

See: https://github.com/citra-emu/citra/pull/6130

core/CMakeLists.txt: Remove duplicate files.

common: Use PROJECT_SOURCE_DIR to find CMakeModules

yuzu qt: Add option to create Windows crash dumps

ci,linux: Support Patreon releases

audio_device: Make AudioDeviceName constructor constexpr

Given the issues with GPU accelerated ASTC decoding with NVIDIA's latest drivers, parallelize astc decoding on the CPU.
Uses half the available threads in the system for astc decoding.

This is just being copied and isn't modified at all.

These two don't modify member state.

This doesn't modify member state.

We can also mark the parameter of AppendError as const as well, since it
isn't modified.

This doesn't modify instance state.

These functions don't modify class state, so we can mark them as such

These don't affect class state, so we can mark them as such.

This function doesn't modify the passed in buffer, so we can make that
explicit.

Simplifies the indexing code a little bit.

These functions don't modify the passed in audio buffers, so we can
signify that in the interface.

colorful theme has been default theme for awhile. having colorful theme
try and grab icons from other theme doesn't work on Linux.

Also adding two additional icons, info is to hint to the user that they
should hit verify after pasting in a token, sync is to show that the
verification is occurring.
