nptl: Eliminate the __static_tls_size, __static_tls_align_m1 variables
Use the __nptl_tls_static_size_for_stack inline function instead, and the GLRO (dl_tls_static_align) value directly. The computation of GLRO (dl_tls_static_align) in _dl_determine_tlsoffset ensures that the alignment is at least TLS_TCB_ALIGN, which at least STACK_ALIGN (see allocate_stack). Therefore, the additional rounding-up step is removed. ALso move the initialization of the default stack size from __pthread_initialize_minimal_internal to __pthread_early_init. This introduces an extra system call during single-threaded startup, but this simplifies the initialization sequence. No locking is needed around the writes to __default_pthread_attr because the process is single-threaded at this point. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>
