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.

CMake: Fix message levels for error conditions during configuration Make messages which should be fatal, actually fail the build. - FATAL is not a valid mode keyword. The full list is available in the docs: https://cmake.org/cmake/help/v3.19/command/message.html - SEND_ERROR doesn't immediately stop processing, FATAL_ERROR does. We should immediately stop if the Toolchain is not present. - The app icon size validation was just a WARNING that is easy to overlook. We should promote it to a FATAL_ERROR so that people will not overlook the issue when adding a new application. We can only make the small icon message FATAL_ERROR, as there is currently one violation of the medium app icon validation.

Meta: Switch to a SuperBuild that splits host and target builds Replace the old logic where we would start with a host build, and swap all the CMake compiler and target variables underneath it to trick CMake into building for Serenity after we configured and built the Lagom code generators. The SuperBuild creates two ExternalProjects, one for Lagom and one for Serenity. The Serenity project depends on the install stage for the Lagom build. The SuperBuild also generates a CMakeToolchain file for the Serenity build to use that replaces the old toolchain file that was only used for Ports. To ensure that code generators are rebuilt when core libraries such as AK and LibCore are modified, developers will need to direct their manual `ninja` invocations to the SuperBuild's binary directory instead of the Serenity binary directory. This commit includes warning coalescing and option style cleanup for the affected CMakeLists in the Kernel, top level, and runtime support libraries. A large part of the cleanup is replacing USE_CLANG_TOOLCHAIN with the proper CMAKE_CXX_COMPILER_ID variable, which will no longer be confused by a host clang compiler.

Second, it enables the upcoming SuperBuild changes to set() the options in the SuperBuild's CMake cache and forward each target's options to the corresponding ExternalProject.

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.

CMake: Hide KMALLOC_VERIFY_NO_SPINLOCK_HELD so folks don't find it Since I introduced this functionality there has been a steady stream of people building with `ALL_THE_DEBUG_MACROS` and trying to boot the system, and immediately hitting this assert. I have no idea why people try to build with all the debugging enabled, but I'm tired of seeing the bug reports about asserts we know are going to happen at this point. So I'm hiding this value under the new ENABLE_ALL_DEBUG_FACILITIES flag instead. This is only set by CI, and hopefully no-one will try to build with this thing (It's documented as not recommended). Fixes: #7527

Kernel: Add option to build with coverage instrumentation and KCOV GCC and Clang allow us to inject a call to a function named __sanitizer_cov_trace_pc on every edge. This function has to be defined by us. By noting down the caller in that function we can trace the code we have encountered during execution. Such information is used by coverage guided fuzzers like AFL and LibFuzzer to determine if a new input resulted in a new code path. This makes fuzzing much more effective. Additionally this adds a basic KCOV implementation. KCOV is an API that allows user space to request the kernel to start collecting coverage information for a given user space thread. Furthermore KCOV then exposes the collected program counters to user space via a BlockDevice which can be mmaped from user space. This work is required to add effective support for fuzzing SerenityOS to the Syzkaller syscall fuzzer. :^) :^)

To ensure that code generators are rebuilt when core libraries such as AK and LibCore are modified, developers will need to direct their manual `ninja` invocations to the SuperBuild's binary directory instead of the Serenity binary directory.

Everything: Add `-Wnon-virtual-dtor` flag This flag warns on classes which have `virtual` functions but do not have a `virtual` destructor. This patch adds both the flag and missing destructors. The access level of the destructors was determined by a two rules of thumb: 1. A destructor should have a similar or lower access level to that of a constructor. 2. Having a `private` destructor implicitly deletes the default constructor, which is probably undesirable for "interface" types (classes with only virtual functions and no data). In short, most of the added destructors are `protected`, unless the compiler complained about access.

Toolchain+Meta: Update LLVM version to 13.0.0 This commit updates the Clang toolchain's version to 13.0.0, which comes with better C++20 support and improved handling of new features by clang-format. Due to the newly enabled `-Bsymbolic-functions` flag, our Clang binaries will only be 2-4% slower than if we dynamically linked them, but we save hundreds of megabytes of disk space. The `BuildClang.sh` script has been reworked to build the entire toolchain in just three steps: one for the compiler, one for GNU binutils, and one for the runtime libraries. This reduces the complexity of the build script, and will allow us to modify the CI configuration to only rebuild the libraries when our libc headers change. Most of the compile flags have been moved out to a separate CMake cache file, similarly to how the Android and Fuchsia toolchains are implemented within the LLVM repo. This provides a nicer interface than the heaps of command-line arguments. We no longer build separate toolchains for each architecture, as the same Clang binary can compile code for multiple targets. The horrible mess that `SERENITY_CLANG_ARCH` was, has been removed in this commit. Clang happily accepts an `i686-pc-serenity` target triple, which matches what our GCC toolchain accepts.

Meta+LibC: Don't allow text relocations in SerenityOS libraries The `-z,text` linker flag causes the linker to reject shared libraries and PIE executables that have textrels. Our code mostly did not use these except in one place in LibC, which is changed in this commit. This makes GNU ld match LLD's behavior, which has this option enabled by default. TEXTRELs pose a security risk, as performing these relocations require executable pages to be written to by the dynamic linker. This can significantly weaken W^X hardening mitigations. Note that after this change, TEXTRELs can still be used in ports, as the dynamic loader code is not changed. There are also uses of it in the kernel, removing which are outside the scope of this PR. To allow those, `-z,notext` is added.

Everywhere: Move all host tools into the Lagom/Tools subdirectory This allows us to remove all the add_subdirectory calls from the top level CMakeLists.txt that referred to targets linking LagomCore. Segregating the host tools and Serenity targets helps us get to a place where the main Serenity build can simply use a CMake toolchain file rather than swapping all the compiler/sysroot variables after building host libraries and tools.

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.

Userland: Port UBSAN implementation to userspace Take Kernel/UBSanitizer.cpp and make a copy in LibSanitizer. We can use LibSanitizer to hold other sanitizers as people implement them :^). To enable UBSAN for LibC, DynamicLoader, and other low level system libraries, LibUBSanitizer is built as a serenity_libc, and has a static version for LibCStatic to use. The approach is the same as that taken in Note that this means now UBSAN is enabled for code generators, Lagom, Kernel, and Userspace with -DENABLE_UNDEFINED_SANTIZER=ON. In userspace however, UBSAN is not deadly (yet). Co-authored-by: ForLoveOfCats <ForLoveOfCats@vivaldi.net>

Meta: Switch to a SuperBuild that splits host and target builds Replace the old logic where we would start with a host build, and swap all the CMake compiler and target variables underneath it to trick CMake into building for Serenity after we configured and built the Lagom code generators. The SuperBuild creates two ExternalProjects, one for Lagom and one for Serenity. The Serenity project depends on the install stage for the Lagom build. The SuperBuild also generates a CMakeToolchain file for the Serenity build to use that replaces the old toolchain file that was only used for Ports. To ensure that code generators are rebuilt when core libraries such as AK and LibCore are modified, developers will need to direct their manual `ninja` invocations to the SuperBuild's binary directory instead of the Serenity binary directory. This commit includes warning coalescing and option style cleanup for the affected CMakeLists in the Kernel, top level, and runtime support libraries. A large part of the cleanup is replacing USE_CLANG_TOOLCHAIN with the proper CMAKE_CXX_COMPILER_ID variable, which will no longer be confused by a host clang compiler.

Meta: Add support for declaring components Components are a group of build targets that can be built and installed separately. Whether a component should be built can be configured with CMake arguments: -DBUILD_<NAME>=ON|OFF, where <NAME> is the name of the component (in all caps). Components can be marked as REQUIRED if they're necessary for a minimally functional base system or they can be marked as RECOMMENDED if they're not strictly necessary but are useful for most users. A component can have an optional description which isn't used by the build system but may be useful for a configuration UI. Components specify the TARGETS which should be built when the component is enabled. They can also specify other components which they depend on (with DEPENDS). This also adds the BUILD_EVERYTHING CMake variable which lets the user build all optional components. For now this defaults to ON to make the transition to the components-based build system easier. The list of components is exported as an INI file in the build directory (e.g. Build/i686/components.ini). Fixes #8048.

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. :^)
