vm_eval.c (rb_f_caller): caller() method accepts second optional argument n' which specify how many frames should return. For example, caller(0, 1)' returns only one frame information which calls caller() method. If there are less than n frame information, then all frame information are returned. If n is 0, then always return []. This fix is part of [ruby-dev:42345] [Ruby 1.9-Feature#3917]. However, performance and features are not enough. RDoc is also not available.
test/ruby/test_backtrace.rb: add a test for above.
