* range.c (range_cover): add code for range argument.
If the argument is a Range, check it is or is not
covered by the reciver. If it can be treated as a
sequence, this method treats it that way.
* test/ruby/test_range.rb (class TestRange): add tests
for this feature.

This commit introduces new core class Enumerator::ArithmeticSequence.
Enumerator::ArithmeticSequence is a subclass of Enumerator, and
represents a number generator of an arithmetic sequence.
After this commit, Numeric#step and Range#step without blocks
returned an ArithmeticSequence object instead of an Enumerator.
This class introduces the following incompatibilities:
- You can create a zero-step ArithmeticSequence,
and its size is not ArgumentError, but Infinity.
- You can create a negative-step ArithmeticSequence from a range.

Also, Range#min raises an error if it is endless and a comparison method
is specified.

Now endless range can be created by either a literal `(1..)` or explicit
range creation `Range.new(1, nil)`. [Bug #14845]
This change is intended for "early failure"; for example,
`(1..var).to_a` causes out of memory if `var` is inadvertently nil.

* range.c (range_each): endless range begins with string-like
object should iterate from the converted result string, as well
as `#each` on a string-end range or `#step` method on an endless
range, i.e., `begin.succ` should not be called.

range.c: cast the function type to meet the declaration
This change is for fixing build error on AppVeyor:

Typical usages:
```
p ary[1..] # drop the first element; identical to ary[1..-1]
(1..).each {|n|...} # iterate forever from 1; identical to 1.step{...}

For checking whether an object is an Integer, because a subclass of
Integer is meaningless in Ruby, RB_INTEGER_TYPE_P is better than
rb_obj_is_kind_of for speed.
* object.c (rb_to_integer): Use RB_INTEGER_TYPE_P instead of rb_obj_is_kind_of.
* object.c (rb_check_to_integer): ditto.
* range.c (range_max): ditto.

* range.c (rb_range_values): use rb_check_funcall instead of
calling rb_respond_to then rb_funcall, and allow `begin` and
`end` to be private as well as other internal conversions.
