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.

Everything: Move to SPDX license identifiers in all files. SPDX License Identifiers are a more compact / standardized way of representing file license information. See: https://spdx.dev/resources/use/#identifiers This was done with the `ambr` search and replace tool. ambr --no-parent-ignore --key-from-file --rep-from-file key.txt rep.txt *

AK+Everywhere: Rename String to DeprecatedString We have a new, improved string type coming up in AK (OOM aware, no null state), and while it's going to use UTF-8, the name UTF8String is a mouthful - so let's free up the String name by renaming the existing class. Making the old one have an annoying name will hopefully also help with quick adoption :^)

IPCCompiler: More work towards AudioServer bringup - Add IEndpoint::handle(IMessage), a big switch table on message type. handle() will return a response message for synchronous messages, and return nullptr otherwise. - Use i32 instead of int for everything - Make IMessage::encode() const - Make IEndpoint::decode_message() static, this allows template code to decode messages without an endpoint instance on hand.

Everywhere: Forward declare structs as structs While structs being forward declared as classes is not strictly an issue, Clang complains as this is not portable code, since some ABIs treat classes declared as `class` and `struct` differently. It's easier to fix these than to reason about explicitly disabling another warning.

IPCCompiler: Remove hardcoded endpoint magic, attempt deux This patch removes the IPC endpoint numbers that needed to be specified in the IPC files. Since the string hash is a (hopefully) collision free number that depends on the name of the endpoint, we now use that instead. :^) Additionally, endpoint magic is now treated as a u32, because endpoint numbers were never negative anyway. For cases where the endpoint number does have to be hardcoded (a current case is LookupServer because the endpoint number must be known in LibC), the syntax has been made more explicit to avoid confusing those unfamiliar. To hardcode the endpoint magic, the following syntax is now used: endpoint EndpointName [magic=1234]
