Follow-fork message printing improvements
This commit modifies the code that prints attach and detach messages related to following fork and vfork. The changes include using target_terminal_ours_for_output instead of target_terminal_ours, printing "vfork" instead of "fork" for all vfork-related messages, and using _() for the format strings of all of the messages. We also add a "detach" message for when a fork parent is detached. Previously in this case the only message was notification of attaching to the child. We still do not print any messages when following the parent and detaching the child (the default). The rationale for this is that from the user's perspective the new child was never attached. Note that all of these messages are only printed when 'verbose' is set or when debugging is turned on. The tests gdb.base/foll-fork.exp and gdb.base/foll-vfork.exp were modified to check for the new message. Tested on x64 Ubuntu Lucid, native only. gdb/ChangeLog: * infrun.c (follow_fork_inferior): Update fork message printing to use target_terminal_ours_for_output instead of target_terminal_ours, to use _() for all format strings, to print "vfork" instead of "fork" for vforks, and to add a detach message. (handle_vfork_child_exec_or_exit): Update message printing to use target_terminal_ours_for_output instead of target_terminal_ours, to use _() for all format strings, and to fix some formatting. gdb/testsuite/ChangeLog: * gdb.base/foll-fork.exp (test_follow_fork, catch_fork_child_follow): Check for updated fork messages emitted from infrun.c. * gdb.base/foll-vfork.exp (vfork_parent_follow_through_step, vfork_parent_follow_to_bp, vfork_and_exec_child_follow_to_main_bp, vfork_and_exec_child_follow_through_step): Check for updated vfork messages emitted from infrun.c.
