Introduce scoped_restore_signal
We currently have scoped_restore_sigttou and scoped_restore_sigpipe doing basically the same thing -- temporarily ignoring a specific signal. This patch introduce a scoped_restore_signal type that can be used for both. This will become more important for the next patch which changes how the signal-ignoring is implemented. scoped_restore_sigpipe is a straight alias to scoped_restore_signal<SIGPIPE> on systems that define SIGPIPE, and an alias to scoped_restore_signal_nop (a no-op version of scoped_restore_signal) otherwise. scoped_restore_sigttou is not a straight alias because it wants to check the job_control global. gdb/ChangeLog: yyyy-mm-dd Pedro Alves <pedro@palves.net> * gdbsupport/scoped_ignore_signal.h: New. * compile/compile.c: Include gdbsupport/scoped_ignore_signal.h instead of <signal.h>. Don't include <unistd.h>. (scoped_ignore_sigpipe): Remove. * gdbsupport/scoped_ignore_sigttou.h: Include gdbsupport/scoped_ignore_signal.h instead of <signal.h>. Don't include <unistd.h>. (lazy_init): New. (scoped_ignore_sigttou): Reimplement using scoped_ignore_signal and lazy_init. Change-Id: Ibb44d0bd705e96df03ef0787c77358a4a7b7086c
