This applies the second part of GDB's End of Year Procedure, which
updates the copyright year range in all of GDB's files.
gdb/ChangeLog:
Update copyright year range in all GDB files.
Two modifications:
1. The addition of 2013 to the copyright year range for every file;
2. The use of a single year range, instead of potentially multiple
year ranges, as approved by the FSF.
* linux-nat.c (linux_nat_wait): Only use set_ignore_sigint in
all-stop mode.
gdb/testsuite/
* lib/mi-support.exp (mi_expect_interrupt): New.
(mi_reverse_list, mi_check_thread_states): New, moved and renamed
from gdb.mi/mi-nonstop.exp.
* gdb.mi/mi-nsintrall.exp, gdb.mi/nsintrall.c: New.
* gdb.mi/mi-nonstop.exp (myreverse, check_thread_states): Moved to
lib/mi-support.exp.
Use mi_check_thread_states throughout. Avoid ".*" and do not
require an anchor after -exec-run.
