* thread.c: add `Thread#backtrace_locations' method.
This method is similart to `caller_locations' method for
specific method.
And fix to accept `level' and `n' parameters for `Thread#backtrace'
and `Thread#backtrace_locations'.
`caller' (and `caller_locations') do not return `caller' method
frame.
However, `Thread#backtrace' (and `Thread#backtrace_locations')
return `Thread#backtrace' method frame itself
if `Thread.current.backtrace' was called.
* vm_backtrace.c: ditto.
* internal.h: ditto.
* test/ruby/test_backtrace.rb: add tests.
