Subject: [PATCH 01/13] Add SpaceInParensOption for __attribute__ keyword

The __attribute((specifier-list)) currently is formatted based on the
SpacesInParensOptions.Other (previously, SpacesInParentheses). This change
allows finer control over addition of spaces between the consecutive parens,
and between the inner parens and the list of attribute specifiers.
