cmake: Make setting CMAKE_BUILD_TYPE an error. I tried setting it to Release, then noticed that it didn't build due to gcc's optimizer-level dependent warnings and -Werror, then started fixing the warnings for a bit (all false positives), then looked at the global CMakeLists.txt and realized that the default build is aleady using compiler optimizations. It looks like people aren't supposed to change this, so make that explicit to be friendly to people familiar with cmake but new to serenity.

option(ENABLE_ADDRESS_SANITIZER "Enable address sanitizer testing in gcc/clang" FALSE)
Kernel: Initial integration of Kernel Address Sanitizer (KASAN) KASAN is a dynamic analysis tool that finds memory errors. It focuses mostly on finding use-after-free and out-of-bound read/writes bugs. KASAN works by allocating a "shadow memory" region which is used to store whether each byte of memory is safe to access. The compiler then instruments the kernel code and a check is inserted which validates the state of the shadow memory region on every memory access (load or store). To fully integrate KASAN into the SerenityOS kernel we need to: a) Implement the KASAN interface to intercept the injected loads/stores. void __asan_load*(address); void __asan_store(address); b) Setup KASAN region and determine the shadow memory offset + translation. This might be challenging since Serenity is only 32bit at this time. Ex: Linux implements kernel address -> shadow address translation like: static inline void *kasan_mem_to_shadow(const void *addr) { return ((unsigned long)addr >> KASAN_SHADOW_SCALE_SHIFT) + KASAN_SHADOW_OFFSET; } c) Integrating KASAN with Kernel allocators. The kernel allocators need to be taught how to record allocation state in the shadow memory region. This commit only implements the initial steps of this long process: - A new (default OFF) CMake build flag `ENABLE_KERNEL_ADDRESS_SANITIZER` - Stubs out enough of the KASAN interface to allow the Kernel to link clean. Currently the KASAN kernel crashes on boot (triple fault because of the crash in strlen other sanitizer are seeing) but the goal here is to just get started, and this should help others jump in and continue making progress on KASAN.

CMake: Set C++20 mode in canonical cmake Problem: - Setting `CMAKE_CXX_FLAGS` directly to effect the version of the C++ standard being used is no longer the recommended best practice. Solution: - Set C++20 mode in the compiler by setting `CMAKE_CXX_STANDARD`. - Force the build system generator not to fallback to the latest standard supported by the compiler by enabling `CMAKE_CXX_STANDARD_REQUIRED`. This shouldn't ever be a problem though since the toolchain is tightly controlled. - Disable GNU compiler extensions by disabling `CMAKE_CXX_EXTENSIONS` to preserve the previous flags.

Build: Support make's and ninja's restat optimization After running a build command, make by default stat()s the command's output, and if it wasn't touched, then it cancels all build steps that were scheduled only because this command was expected to change the output. Ninja has the same feature, but it's opt-in behind the per-command "restat = 1" setting. However, CMake enables it by default for all custom commands. Use Meta/write-only-on-difference.sh to write the output to a temporary file, and then copy the temporary file only to the final location if the contents of the output have changed since last time. write-only-on-difference.sh automatically creates the output's parent directory, so stop doing that in CMake. Reduces the number of build steps that run after touching a file in LibCore from 522 to 312. Since we now no longer trigger the CMake special case "If COMMAND specifies an executable target name (created by the add_executable() command), it will automatically be replaced by the location of the executable created at build time", we now need to use qualified paths to the generators. Somewhat related to #2877.

Build + LibC: Enable -fstack-protector-strong in user space Modify the user mode runtime to insert stack canaries to find stack corruptions. The `-fstack-protector-strong` variant was chosen because it catches more issues than vanilla `-fstack-protector`, but doesn't have substantial performance impact like `-fstack-protector-all`. Details: -fstack-protector enables stack protection for vulnerable functions that contain: * A character array larger than 8 bytes. * An 8-bit integer array larger than 8 bytes. * A call to alloca() with either a variable size or a constant size bigger than 8 bytes. -fstack-protector-strong enables stack protection for vulnerable functions that contain: * An array of any size and type. * A call to alloca(). * A local variable that has its address taken. Example of it catching corrupting in the `stack-smash` test: ``` courage ~ $ ./user/Tests/LibC/stack-smash [+] Starting the stack smash ... Error: Stack protector failure, stack smashing detected! Shell: Job 1 (/usr/Tests/LibC/stack-smash) Aborted ```

CMake: Use add_compile_options instead of appending to CMAKE_CXX_FLAGS Problem: - Appending to CMAKE_CXX_FLAGS for everything is cumbersome. Solution: - Use the `add_compile_options` built-in function to handle adding compiler options (and even de-duplicating).

Toolchain+LibC: Fix usage of crt files We now configure the gcc spec files to use a different crt files for static & PIE binaries. This relieves us from the need to explicitly specify the desired crt0 file in cmake scripts.

Userland: Add LibSystem and funnel all syscalls through it This achieves two things: - Programs can now intentionally perform arbitrary syscalls by calling syscall(). This allows us to work on things like syscall fuzzing. - It restricts the ability of userspace to make syscalls to a single 4KB page of code. In order to call the kernel directly, an attacker must now locate this page and call through it.

TextEditor: Move the main window UI to JSON This is our first client of the new JSON GUI declaration thingy. The skeleton of the TextEditor app GUI is now declared separately from the C++ logic, and we use the Core::Object::name() of widgets to locate them once they have been instantiated by the GUI builder.

Ports: Fix CMake-based ports The SDL port failed to build because the CMake toolchain filed pointed to the old root. Now the toolchain file assumes that the Root is in Build/Root. Additionally, the AK/ and Kernel/ headers need to be installed in the root too.

Base: Remove /res/pci.ids and download at build time instead This is an external file from https://pci-ids.ucw.cz that's being updated daily, which was imported a while ago but probably shouldn't live in the SerenityOS repository in the first place (or else would need manual maintenance). The legal aspects of redistributing this file as we currently do are not quite clear to me, they require either GPL (version 2 or later) or 3-clause BSD - Serenity is 2-clause BSD... The current version we use is 2019.08.08, so quite outdated - and while most of these devices are obviously not supported, we're still capable of *listing* them, so having an up-to-date version with recent additions and fixes would be nice. This updates the root CMakeLists.txt to check for existence of the file and download it if not found - effectively on every fresh build. Do note that this is not a critical file, and the system runs just fine should this ever fail. :^)
