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.

CMake: Verify the GCC host version is new enough to build serenity There are lots of people who have issues building serenity because they don't read the build directions closely enough and have an unsupported GCC version as their host compiler.

Kernel: Add ENABLE_EXTRA_KERNEL_DEBUG_SYMBOLS option to set Og and ggdb3 When debugging kernel code, it's necessary to set extra flags. Normal advice is to set -ggdb3. Sometimes that still doesn't provide enough debugging information for complex functions that still get optimized. Compiling with -Og gives the best optimizations for debugging, but can sometimes be broken by changes that are innocuous when the compiler gets more of a chance to look at them. The new CMake option enables both compile options for kernel code.

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.

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).

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>

DevTools: Add StateMachineGenerator utility This program turns a description of a state machine that takes its input byte-by-byte into C++ code. The state machine is described in a custom format as specified below: ``` // Comments are started by two slashes, and cause the rest of the line // to be ignored @name ExampleStateMachine // sets the name of the generated class @namespace Test // sets the namespace (optional) @begin Begin // sets the state the parser will start in // The rest of the file contains one or more states and an optional // @anywhere directive. Each of these is a curly bracket delimited set // of state transitions. State transitions contain a selector, the // literal "=>" and a (new_state, action) tuple. Examples: // 0x0a => (Begin, PrintLine) // [0x00..0x1f] => (_, Warn) // '_' means no change // [0x41..0x5a] => (BeginWord, _) // '_' means no action // Rules common to all states. These take precedence over rules in the // specific states. @anywhere { 0x0a => (Begin, PrintLine) [0x00..0x1f] => (_, Warn) } Begin { [0x41..0x5a] => (Word, _) [0x61..0x7a] => (Word, _) // For missing values, the transition (_, _) is implied } Word { // The entry action is run when we transition to this state from a // *different* state. @anywhere can't have this @entry IncreaseWordCount 0x09 => (Begin, _) 0x20 => (Begin, _) // The exit action is run before we transition to any *other* state // from here. @anywhere can't have this @exit EndOfWord } ``` The generated code consists of a single class which takes a `Function<Action, u8>` as a parameter in its constructor. This gets called whenever an action is to be done. This is because some input might not produce an action, but others might produce up to 3 (exit, state transition, entry). The actions allow us to build a more advanced parser over the simple state machine. The sole public method, `void advance(u8)`, handles the input byte-by-byte, managing the state changes and requesting the appropriate Action from the handler. Internally, the state transitions are resolved via a lookup table. This is a bit wasteful for more complex state machines, therefore the generator is designed to be easily extendable with a switch-based resolver; only the private `lookup_state_transition` method needs to be re-implemented. My goal for this tool is to use it for implementing a standard-compliant ANSI escape sequence parser for LibVT, as described on <https://vt100.net/emu/dec_ansi_parser>

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.

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.

Meta: Disable -Wmaybe-uninitialized It's prone to finding "technically uninitialized but can never happen" cases, particularly in Optional<T> and Variant<Ts...>. The general case seems to be that it cannot infer the dependency between Variant's index (or Optional's boolean state) and a particular alternative (or Optional's buffer) being untouched. So it can flag cases like this: ```c++ if (index == StaticIndexForF) new (new_buffer) F(move(*bit_cast<F*>(old_buffer))); ``` The code in that branch can _technically_ make a partially initialized `F`, but that path can never be taken since the buffer holding an object of type `F` and the condition being true are correlated, and so will never be taken _unless_ the buffer holds an object of type `F`. This commit also removed the various 'diagnostic ignored' pragmas used to work around this warning, as they no longer do anything.

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: 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.

Tests: Establish root Tests directory, move Userland/Tests there With the goal of centralizing all tests in the system, this is a first step to establish a Tests sub-tree. It will contain all of the unit tests and test harnesses for the various components in the system.

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. :^)

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.
