Update magic numbers and default identifiers across codebase:
- UUID default value
- Thread magic number
- Amiibo name
- Vulkan cache magic number
- Shader cache magic number
- In commit b3facaa6bb30cdc39f2b7d632fef1e3bfeee7785, the copyright header was
updated to include "Citron Homebrew Project" across multiple files, regardless
of whether any contributions were made.
- This commit removes the incorrect attribution and reverts the copyright header
to its previous state.
- Copyright attribution should only be added when meaningful contributions have
been made to the file.
- This commit ensures proper compliance with copyright standards and maintains
correct attribution to the respective contributors.
- Special thanks to Tachi for pointing out the need for these corrections and
ensuring that proper attribution practices are followed.
This formats all copyright comments according to SPDX formatting guidelines.
Additionally, this resolves the remaining GPLv2 only licensed files by relicensing them to GPLv2.0-or-later.
Now that clang-format makes [[nodiscard]] attributes format sensibly, we
can apply them to several functions within the common library to allow
the compiler to complain about any misuses of the functions.
