libcamera: base: backtrace: Fallback to libunwind for symbolic names
libunwind has an API to provide symbolic names for functions. It's less
optimal than using backtrace_symbols() or libdw, as it doesn't allow
deferring the symbolic names lookup, but it can be usefull as a fallback
if no other option is available.
A sample backtrace when falling back to libunwind looks like
libcamera::VimcCameraData::init()+0xbd
libcamera::PipelineHandlerVimc::match(libcamera::DeviceEnumerator*)+0x3e0
libcamera::CameraManager::Private::createPipelineHandlers()+0x1a7
libcamera::CameraManager::Private::init()+0x98
libcamera::CameraManager::Private::run()+0x9f
libcamera::Thread::startThread()+0xee
decltype(*(std::__1::forward<libcamera::Thread*>(fp0)).*fp()) std::__1::__invoke<void (libcamera::Thread::*)(), libcamera::Thread*, void>(void (libcamera::Thread::*&&)(), libcamera::Thread*&&)+0x77
void std::__1::__thread_execute<std::__1::unique_ptr<std::__1::__thread_struct, std::__1::default_delete<std::__1::__thread_struct> >, void (libcamera::Thread::*)(), libcamera::Thread*, 2ul>(std::__1::tuple<std::__1::unique_ptr<std::__1::__thread_struct, std::__1::default_delete<std::__1::__thread_struct> >, void (libcamera::Thread::*)(), libcamera::Thread*>&, std::__1::__tuple_indices<2ul>)+0x3e
void* std::__1::__thread_proxy<std::__1::tuple<std::__1::unique_ptr<std::__1::__thread_struct, std::__1::default_delete<std::__1::__thread_struct> >, void (libcamera::Thread::*)(), libcamera::Thread*> >(void*)+0x62
start_thread+0xde
