Kouhei Sutou 5ec676aa37 Fix splat and multiple assignments 
Case1: From variable

Code:

    a = [1, 2, 3, 4, 5]
    b, c, *d = a

    p [a, b, c, d]

Before:

    [[1, 2, 3, 4, 5], 1, 2, []]

After:

    [[1, 2, 3, 4, 5], 1, 2, [3, 4, 5]]

Ruby:

    [[1, 2, 3, 4, 5], 1, 2, [3, 4, 5]]

Case2: From variables

Code:

    a = [1, 2, 3]
    b = [4, 5, 6, 7]
    c, d, *e, f, g = *a, *b

    p [a, b, c, d, e, f, g]

Before:

    [[1, 2, 3], [4, 5, 6, 7], 1, 2, [], 6, 7]

After:

    [[1, 2, 3], [4, 5, 6, 7], 1, 2, [3, 4, 5], 6, 7]

Ruby:

    [[1, 2, 3], [4, 5, 6, 7], 1, 2, [3, 4, 5], 6, 7]

Case 3: "for"

Code:

    a = [1, 2, 3, 4, 5, 6, 7]
    for b, c, *d, e, f in [a] do
      p [a, b, c, d, e, f]
    end

Before:

    [[1, 2, 3, 4, 5, 6, 7], 1, 2, [], nil, nil]

After:

    [[1, 2, 3, 4, 5, 6, 7], 1, 2, [3, 4, 5], 6, 7]

cremno ef59f553a3 invalid base shouldn't silently fail 
Revert 44a5809224 and check range of
`base` with `mrb_assert`.
It actually can only be either 2, 8, 10 or 16 (and never 0), unless
mruby sources are modified. But I don't see a reason to impose further
limits.

cremno 91c22f32f4 rename mrb_str_buf_append to mrb_str_cat_str 
The new name is better and less confusing, because:
  - `mrb_str_append` calls `mrb_str_to_str` and this function doesn't
  - `mrb_str_buf_append` _is_ `mrb_str_cat` for `mrb_value` strings
