Meta: Add license header to source files As suggested by Joshua, this commit adds the 2-clause BSD license as a comment block to the top of every source file. For the first pass, I've just added myself for simplicity. I encourage everyone to add themselves as copyright holders of any file they've added or modified in some significant way. If I've added myself in error somewhere, feel free to replace it with the appropriate copyright holder instead. Going forward, all new source files should include a license header.

LibCore: Automatically create config directories if necessary If the .config directory (or its children, like lib) was deleted, ConfigFile would crash because it would try to open or create a file in a directory that didn't exist. Therefore, for user and library configs (but not system configs), ensure that the parent directories exist. This allows the user to delete the entire .config folder and all apps still work. (Except those which can't handle missing config. That's a separate issue though.) Fixes #13555 Note: Some changes to pledges and unveils are necessary for this to work. The only one who can recreate .config at the moment is ConfigServer, as others probably don't pledge the user home directory.

LibCore: Support using a file descriptor for opening ConfigFile This patch adds support for opening a ConfigFile using a file descriptor rather than trying to open a the file by name directly. In contrast to the previous implementation, ConfigFile now always keeps a reference to an open File and does not reopen it for writing. This requires providing an additional argument to open functions if a file gets opened based on its name and the user of the api intends to write to the file in the future.

Everywhere: Rename {Deprecated => Byte}String This commit un-deprecates DeprecatedString, and repurposes it as a byte string. As the null state has already been removed, there are no other particularly hairy blockers in repurposing this type as a byte string (what it _really_ is). This commit is auto-generated: $ xs=$(ack -l \bDeprecatedString\b\|deprecated_string AK Userland \ Meta Ports Ladybird Tests Kernel) $ perl -pie 's/\bDeprecatedString\b/ByteString/g; s/deprecated_string/byte_string/g' $xs $ clang-format --style=file -i \ $(git diff --name-only | grep \.cpp\|\.h) $ gn format $(git ls-files '*.gn' '*.gni')

LibCore: Add a CConfigFile class, a simple INI file parser. You open the configuration for an app like so: auto config = CConfigFile::get_for_app("MyApp"); This will then open ~/MyApp.ini and parse it for you. Immediately start using it in Minesweeper to load the field size and mine count from a config file.

LibCore: Put all classes in the Core namespace and remove the leading C I've been wanting to do this for a long time. It's time we start being consistent about how this stuff works. The new convention is: - "LibFoo" is a userspace library that provides the "Foo" namespace. That's it :^) This was pretty tedious to convert and I didn't even start on LibGUI yet. But it's coming up next.
