R-Goc 3c7bad32cd AK: Clean up backtraces
This commit replaces the default backtrace logic with cpptrace, for
nicer, colored backtraces. Cpptrace runs on all of our supported
platforms excpet android. As such backtrace.h is left in place.

All the backtrace functions are made noinline to have a consistent
number of frames. A maximum depth parameter is added to dump_backtrace
with a default of 100. This should be enough, and can be easily
changed, and allows for limiting the maximum depth.

Setting the LADYBIRD_BACKTRACE_SNIPPETS environment variable enables
surrouding code snippets in the backtrace. Specifically 2 lines above
and below. This number can be changed by calling snippet_context on the
formatter. For the whole list of options of what can be done with
formatting see the cpptrace repository.

On Windows we skipped frames when verification fails and when
dump_backtrace was added the logic was wrong and would have skipped
frames we care about.

This commit also implements skipping frames on Linux.
The only time where this does not skip all frames is when the call to
backtrace gets intercepted. Then we will end up skipping one frame less
than needed.

To keep delayload on Windows a patch and overlay port is used. When
upstream accepts these changes and vcpkg bumps the version the patch
could be removed to have just the cmake define.

Ladybird

Ladybird is a truly independent web browser, using a novel engine based on web standards.

Important

Ladybird is in a pre-alpha state, and only suitable for use by developers

Features

We aim to build a complete, usable browser for the modern web.

Ladybird uses a multi-process architecture with a main UI process, several WebContent renderer processes, an ImageDecoder process, and a RequestServer process.

Image decoding and network connections are done out of process to be more robust against malicious content. Each tab has its own renderer process, which is sandboxed from the rest of the system.

At the moment, many core library support components are inherited from SerenityOS:

  • LibWeb: Web rendering engine
  • LibJS: JavaScript engine
  • LibWasm: WebAssembly implementation
  • LibCrypto/LibTLS: Cryptography primitives and Transport Layer Security
  • LibHTTP: HTTP/1.1 client
  • LibGfx: 2D Graphics Library, Image Decoding and Rendering
  • LibUnicode: Unicode and locale support
  • LibMedia: Audio and video playback
  • LibCore: Event loop, OS abstraction layer
  • LibIPC: Inter-process communication

How do I build and run this?

See build instructions for information on how to build Ladybird.

Ladybird runs on Linux, macOS, Windows (with WSL2), and many other *Nixes.

How do I read the documentation?

Code-related documentation can be found in the documentation folder.
