Yukihiro "Matz" Matsumoto 05fceb5992 Call exc_debug_info() in mrb_exc_set(); ref #3610 
Otherwise line number information is lacked from exceptions
raised in VM, e.g. "super called outside of method".

Kouhei Sutou f1eb3aea11 Fix segmentation fault by backtrace and GC 
GitHub: fix #3122

It reverts #3126. #3126 fixes the segmentation fault but generates
broken backtrace.

This change fixes the segmentation fault and generates correct
backtrace. The strategy of this change is "generating backtrace while
irep is alive".

/tmp/test.rb:
    def gen
      e0 = nil
      begin
        1.times {
          raise 'foobar'
        }
      rescue => e
        e0 = e
      end
      e0
    end

    e = gen
    GC.start
    gen
    GC.start

    puts e.backtrace.join("\n")

Run:

    % bin/mruby /tmp/test.rb
    /tmp/test.rb:5:in Object.gen
    /home/kou/work/ruby/mruby.kou/mrblib/numeric.rb:77:in Integral#times
    /tmp/test.rb:4:in Object.gen
    /tmp/test.rb:13

FYI:

    % ruby -v /tmp/test.rb
    ruby 2.3.0p0 (2015-12-25) [x86_64-linux-gnu]
    /tmp/test.rb:5:in `block in gen'
    /tmp/test.rb:4:in `times'
    /tmp/test.rb:4:in `gen'
    /tmp/test.rb:13:in `<main>'

Kouhei Sutou a561bdb25f Support backtrace after method calls 
GitHub: fix #2902, #2917

The current implementation traverses stack to retrieve backtrace. But
stack will be changed when some operations are occurred. It means that
backtrace may be broken after some operations.

This change (1) saves the minimum information to retrieve backtrace when
exception is raised and (2) restores backtrace from the minimum
information when backtrace is needed. It reduces overhead for creating
backtrace Ruby objects.

The space for the minimum information is reused by multiple
exceptions. So memory allocation isn't occurred for each exception.

 * rewrite above macro references throughout the code.
 * update documents

cremno 938ed044f4 use mrb_str_cat_str() instead of mrb_str_append() 
If the argument is always a string, then mrb_str_cat_str() can be
directly called instead of indirectly by mrb_str_append().

mrb_any_to_s(), mrb_obj_as_string(), mrb_inspect() always return a
string.

Yukihiro "Matz" Matsumoto 9c311ddc93 refactor mrb_bob_missing to share raising NoMethodError code; fix #2878 
Note: arguments of mrb_no_method_error() has changed. You need to replace
3rd and 4th argument (say n, argv) to mrb_ary_new_from_values(mrb, n, argv).
