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.
