Pedro Alves 23f238d345 Fix race exposed by gdb.threads/killed.exp 
On GNU/Linux, this test sometimes FAILs like this:

 (gdb) run
 Starting program: /home/pedro/gdb/mygit/build/gdb/testsuite/gdb.threads/killed
 [Thread debugging using libthread_db enabled]
 Using host libthread_db library "/lib64/libthread_db.so.1".
 ptrace: No such process.
 (gdb)
 Program terminated with signal SIGKILL, Killed.
 The program no longer exists.
 FAIL: gdb.threads/killed.exp: run program to completion (timeout)

Note the suspicious "No such process" line (that's errno==ESRCH).
Adding debug output we see:

  LNW: waitpid(-1, ...) returned 18465, ERRNO-OK

  Program terminated with signal SIGKILL, Killed.
  The program no longer exists.
  infrun: stop_waiting
  FAIL: gdb.threads/killed.exp: run program to completion (timeout)

The issue is that here:

  RSRL: resuming stopped-resumed LWP LWP 18465 at 0x3b36af4b51: step=0
  RSRL: resuming stopped-resumed LWP LWP 18461 at 0x3b36af4b51: step=0

The first line shows we had just resumed LWP 18465, which does:

 void *
 child_func (void *dummy)
 {
   kill (pid, SIGKILL);
   exit (1);
 }

So if the kernel manages to schedule that thread fast enough, the
process may be killed before GDB has a chance to resume LWP 18461.

GDBserver has code at the tail end of linux_resume_one_lwp to cope
with this:

~~~
    ptrace (step ? PTRACE_SINGLESTEP : PTRACE_CONT, lwpid_of (thread),
	    (PTRACE_TYPE_ARG3) 0,
	    /* Coerce to a uintptr_t first to avoid potential gcc warning
	       of coercing an 8 byte integer to a 4 byte pointer.  */
	    (PTRACE_TYPE_ARG4) (uintptr_t) signal);

    current_thread = saved_thread;
    if (errno)
      {
	/* ESRCH from ptrace either means that the thread was already
	   running (an error) or that it is gone (a race condition).  If
	   it's gone, we will get a notification the next time we wait,
	   so we can ignore the error.  We could differentiate these
	   two, but it's tricky without waiting; the thread still exists
	   as a zombie, so sending it signal 0 would succeed.  So just
	   ignore ESRCH.  */
	if (errno == ESRCH)
	  return;

	perror_with_name ("ptrace");
      }
~~~

However, that's not a complete fix, because between starting to handle
the resume request and getting that PTRACE_CONTINUE, we run other
ptrace calls that can also fail with ESRCH, and that end up throwing
an error (with perror_with_name).

In the case above, I indeed sometimes see resume_stopped_resumed_lwps
fail in the registers read:

resume_stopped_resumed_lwps (struct lwp_info *lp, void *data)
{
...
      CORE_ADDR pc = regcache_read_pc (regcache);

Or e.g., in 32-bit mode, i386_linux_resume has several calls that can
throw too.

Whether to ignore ptrace errors or not depends on context that is only
available somewhere up the call chain.  So the fix is to let ptrace
errors throw as they do today, and wrap the resume request in a
TRY/CATCH that swallows it iff the lwp that we were trying to resume
is no longer ptrace-stopped.
