Add generic `attributes` extension.

This allows attributes to be added to any block or inline element, in principle. (Though in many cases this will be done by adding a Div or Span container, since pandoc's AST doesn't have a slot for attributes for most elements.) Currently this is only possible with the commonmark and gfm readers. Add `Ext_attributes` constructor for `Extension` [API change].

4936+#### Extension: `attributes` ####

4937+

4938+Allows attributes to be attached to any inline or block-level

4939+element. The syntax for the attributes is the same as that

4940+used in [`header_attributes`][Extension: `header_attributes`].

4941+

4942+- Attributes that occur immediately after an inline

4943+ element affect that element. If they follow a space, then they

4944+ belong to the space. (Hence, this option subsumes

4945+ `inline_code_attributes` and `link_attributes`.)

4946+- Attributes that occur immediately before a block

4947+ element, on a line by themselves, affect that

4948+ element.

4949+- Consecutive attribute specifiers may be used,

4950+ either for blocks or for inlines. Their attributes

4951+ will be combined.

4952+- Attributes that occur at the end of the text of

4953+ a Setext or ATX heading (separated by whitespace

4954+ from the text) affect the heading element. (Hence, this

4955+ option subsumes `header_attributes`.)

4956+- Attributes that occur after the opening fence

4957+ in a fenced code block affect the code block element. (Hence,

4958+ this option subsumes `fenced_code_attributes`.)

4959+- Attributes that occur at the end of a reference

4960+ link definition affect links that refer to that

4961+ definition.

4962+

4963+Note that pandoc's AST does not currently allow attributes

4964+to be attached to arbitrary elements. Hence a Span or Div

4965+container will be added if needed.
