	array.c: always check frozenness in Array#unshift. Fixes [Bug #15952]

	Closes: https://github.com/ruby/ruby/pull/2251

	array.c add back shared array optimization to
	 ary_ensure_room_for_unshift

	Bug fix in commit ec8e5f5aa64e2a [Bug #15952] disabled an
	optimization in this function.

	Mark array as "going to be modified" in `Array#reject!`

	Before this patch, if `reject!` is called on a shared array it can
	mutate the shared array rather than a copy.  This patch marks the array
	as "going to be modified" so that the shared source array isn't
	mutated.

Add FrozenError as a subclass of RuntimeError

2017-12-12T00:46:34+00:00

FrozenError will be used instead of RuntimeError for exceptions
raised when there is an attempt to modify a frozen object. The
reason for this change is to differentiate exceptions related
to frozen objects from generic exceptions such as those generated
by Kernel#raise without an exception class.

array.c: improve operations on small arrays

2017-09-29T07:43:22+00:00

[Feature #13884]

Reduce number of memory allocations for "and", "or" and "diff"
operations on small arrays

Very often, arrays are used to filter parameters and to select
interesting items from 2 collections and very often these
collections are small enough, for example:

```ruby
SAFE_COLUMNS = [:id, :title, :created_at]

def columns
  @all_columns & SAFE_COLUMNS
end
```

In this patch, I got rid of unnecessary memory allocations for
small arrays when "and", "or" and "diff" operations are performed.
