Pass breakpoint type in set_breakpoint_at 

Nowadays, set_breakpoint_at creates breakpoint of type
other_breakpoint, but we also use set_breakpoint_at
in set_reinsert_breakpoint to create breakpoint, so that
we have to overwrite the breakpoint type like this,

  bp = set_breakpoint_at (stop_at, NULL);
  bp->type = reinsert_breakpoint;

which looks not very good.  This patch changes set_breakpoint_at
to receive breakpoint type.  Since set_breakpoint_at is
used in many places, I rename it to set_breakpoint_type_at, and wrap
it with set_breakpoint_at, and pass other_breakpoint.  In this way,
we can call set_breakpoint_type_at with reinsert_breakpoint in
set_reinsert_breakpoint too, and code looks cleaner.
