Function sunrise_libuser::threads::init_main_thread

#[no_mangle]pub extern "C" fn init_main_thread(handle: u32)

Initialisation of the main thread's thread local structures:

When a main thread starts, the kernel puts the handle of its own thread in one of its registers. The main thread should perform relocations, and then call this function, which will:

• put the main thread's handle in MAIN_THREAD_CONTEXT.
• save a pointer to it in its TLS.
• perform copy of .tdata and .tbss for the main thread.
