Refactor Linux raise implementation (BZ#15368)
This patch changes both the nptl and libc Linux raise implementation to avoid the issues described in BZ#15368. The strategy used is summarized in bug report first comment: 1. Block all signals (including internal NPTL ones); 2. Get pid and tid directly from syscall (not relying on cached values); 3. Call tgkill; 4. Restore old signal mask. Tested on x86_64 and i686. [BZ #15368] * sysdeps/unix/sysv/linux/nptl-signals.h (__nptl_clear_internal_signals): New function. (__libc_signal_block_all): Likewise. (__libc_signal_block_app): Likewise. (__libc_signal_restore_set): Likewise. * sysdeps/unix/sysv/linux/pt-raise.c (raise): Use Linux raise.c implementation. * sysdeps/unix/sysv/linux/raise.c (raise): Reimplement to not use the cached pid/tid value in pthread structure.
