1. Move pthread-specific data files from sched/pthread/ to libs/libc/pthread. 2. Remove pthread-specific data functions from syscalls. 3. Implement tls_alloc() and tls_free() with system calls. 4. Reimplement pthread_key_create() and pthread_key_free() using tls_alloc() and tls_free(). 5. Reimplement pthread_set_specific() and pthread_get_specicif() using tls_set_value() and tls_get_value()
