rb_profile_frame_full_label() which returns label with
qualified method name.
Note that in future version of Ruby label() may return
same return value of full_label().

These APIs are designed for profilers, for example, no objectallocation,
and enough information for profilers.
In this version, this API collects only collect Ruby level frames.
This issue will be fixed after Ruby 2.1.

The order of making binding should be stack (frame) top to bottom.

And also fix issue of collecting klass. Collecting klass is same
as TracePoint#defined_class.

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.

Before this commit:
`finish frame' was place holder which indicates that VM loop
needs to return function.
If a C method calls a Ruby methods (a method written by Ruby),
then VM loop will be (re-)invoked. When the Ruby method returns,
then also VM loop should be escaped. `finish frame' has only
one instruction `finish', which returns VM loop function.
VM loop function executes `finish' instruction, then VM loop
function returns itself.
With such mechanism, `leave' instruction (which returns one
frame from current scope) doesn't need to check that this `leave'
should also return from VM loop function.
Strictly, one branch can be removed from `leave' instructon.
Consideration:
However, pushing the `finish frame' needs costs because
it needs several memory accesses. The number of pushing
`finish frame' is greater than I had assumed. Of course,
pushing `finish frame' consumes additional control frame.
Moreover, recent processors has good branch prediction,
with which we can ignore such trivial checking.
After this commit:
Finally, I decide to remove `finish frame' and `finish'
instruction. Some parts of VM depend on `finish frame',
so the new frame flag VM_FRAME_FLAG_FINISH is introduced.
If this frame should escape from VM function loop, then
the result of VM_FRAME_TYPE_FINISH_P(cfp) is true.
`leave' instruction checks this flag every time.
I measured performance on it. However on my environments,
it improves some benchmarks and slows some benchmarks down.
Maybe it is because of C compiler optimization parameters.
I'll re-visit here if this cause problems.
* insns.def (leave, finish): remove finish instruction.
* vm.c, vm_eval.c, vm_exec.c, vm_backtrace.c, vm_dump.c:
apply above changes.

(1) rename rb_location_t to rb_iseq_location_t.
(2) rename field names of rb_iseq_location_t to adjust
RubyVM::Backtrace::Location methods.
(2-1) filename -> path
(2-2) filepath -> absolute_path
(2-3) basename -> base_label
(2-4) name -> label
(3) rename filed name rb_iseq_location_t#line_no to
rb_iseq_location_t#first_lineno to clear purpose of this field.
(4) The field names rb_binding_t#(filename|line_no) are also renamed
to rb_binding_t#(path|first_lineno).

(2) Method name: RubyVM::FrameInfo.caller ->
Kernel.caller_locations.
(3) Instance methods of

(3-1) name -> label
(3-2) basename -> base_label (basename is confusing with
File.basename)
(3-3) line_no -> lineno (We have already similar name
File#lineno, commented by kou [ruby-dev:45686]).
(3-4) filename -> path.
(3-5) filepath -> absolute_path.
(3-5) iseq -> removed (we will make other APIs to access iseq
and other information of frame for debugging).
* test/ruby/test_backtrace.rb: apply above changes.
And apply comment from kou [ruby-dev:45686].

compile time of vm.c.
* internal.h: ditto.
* vm.c, vm_core.h, vm_dump.c, vm_eval.c: ditto.
* vm_eval.c: some functions (callee, etc) moved to vm_backtrace.c.
