* array.c: Harmonize documentation, in particular regarding:

    - methods returning enumerators
    - array methods and argument naming (array -> ary, an_array -> new_ary)
    - minor improvements, typo fixed and styling issues

  Other documentation errors fixed:
    - return value was self instead of a new array (or vice-versa) for
      Array#{pop,shift,permutation,repeated_permutation,keep_if}
    - Array#rindex was missing the form with a block.

* dir.c: ditto.

* enum.c: ditto. Modified Enumerable#reverse_each' documentation to clarify
  that #each will be finish before any element is yielded.

* error.c: ditto.

* gc.c: ditto.

* hash.c: ditto.

* io.c: ditto. IO#{codepoints,each_codepoint} fixed as per [ruby-core:23948]

* numeric.c: ditto.

* range.c: ditto.

* string.c: ditto.

* struct.c: ditto.

* vm_eval.c: ditto.
