[PATCH 00/24] Remove gdb,noinferiorio from gdbserver boards

[Pedro Alves <palves@redhat.com>]

This series finishes what was started here:

  https://sourceware.org/ml/gdb-patches/2015-02/msg00655.html

In a nutshell:
  
 - Make a few tests that are currently relying on inferior I/O to not
   do that anymore.

 - Convert all the remaining tests that rely on inferior I/O to use
   $inferior_spawn_id.

 - Add a gdb_test_stdio helper used by most of the above.

 - Unbuffer all tests that rely on stdio, using the same mechanism
   that ended up used in interrupt.exp, in the series in the url
   above.

 - Remove gdb,noinferiorio from our gdbserver boards, so the tests run
   (against gdbserver).

Tested on x86_64 Fedora 20, native, native-gdbserver and also against
remote gdbserver with no pseudo-tty, which requires the unbuffering.

I've pushed this to users/palves/inferior_spawn_id for review and
testing convenience.

Pedro Alves (24):
  gdb_test_multiple match eof of any spawn_id
  gdb.base/interrupt.exp: Rename saw_eof to saw_end_of_file
  Fix gdb.base/interrupt.exp racy fail against gdbserver
  Don't rely on inferior I/O in gdb.base/siginfo-addr.exp
  Don't rely on inferior I/O in {call-signal-resume, unwindonsignal}.exp
  Don't rely on inferior I/O in gdb.base/restore.exp
  Introduce gdb_test_stdio
  Make gdb.base/sizeof.exp use gdb_test_stdio
  Make gdb.base/call-strs.exp use gdb_test_stdio
