Nicety for those using VSCode

[maxgallup]

Hey @hammertux,

I've added support for a VSCode feature that allows you to open the project inside of a container with all dependencies preinstalled (Dev Containers). All of the make * commands from Lecture 01 seem to work. This allows us to forego installing dependencies to the host which can always be a pain and for those not on running Linux this makes life easier.

Additionally, it might also be nice to include a launch.json VSCode debug configuration, such that you can debug using VSCode's debug interface. After setting it up just run make qemu-nox-gdb, and then hit F5 in VSCode.

// Add to the configurations list in .vscode/launch.json  
"configurations": [
    {
        "name": "Debug Kernel with GDB",
        "type": "cppdbg",
        "request": "launch",
        "program": "${workspaceFolder}/obj/kernel/kernel",
        "args": [],
        "stopAtEntry": true,
        "cwd": "${workspaceFolder}",
        "environment": [],
        "externalConsole": false,
        "MIMode": "gdb",
        "miDebuggerPath": "/usr/bin/gdb",
        "setupCommands": [
            {
                "description": "Load GDB commands from .gdbrc",
                "text": "source ${workspaceFolder}/.gdbrc",
                "ignoreFailures": false
            }
        ]
    }
]

Finally, for proper clangd language server support you might want to add a .clangd file as well. Make sure to set the include directory correctly (in the .clangd file, see the "-I..." below) and to install the clangd and C/C++ VSCode extensions.

CompileFlags:
  Add:
    - "-I/workspace/include"
    - "-DKERNEL_VMA=0xFFFF800000000000"
    - "-DKERNEL_LMA=0x100000"

For an additional mount you'll have to add the following to the devcontainer.json.

    "workspaceMount": "source=${localWorkspaceFolder},target=/workspace,type=bind",
    "workspaceFolder": "/workspace"

I don't use VS, and I am not responsible for this repo, but I know a curl | sh when I see one
