The default definitions and undefinitions of macros used for built-in
descriptions (SIMPLE_VALUE, NUMBER_VALUE, STRING_VALUE, OBJECT_VALUE,
ROUTINE, ACCESSOR_READ_WRITE, ACCESSOR_READ_ONLY) are heavily cloned
all over the builtin-objects directory. This commit factors them out
into two header files, which are then included in the place of the
clones. This way, maintenance becomes a lot easier: e.g., if a new
macro gets introduced, default definition and undefinition don't have
to be added to all description files (of which there are 56 right now,
and their number will most probably just grow).

`Object.prototype.__proto__` has been implemented by most JS
engines to give R/W access to prototype chains, well before it made
it into the standard. JerryScript has decided not to implement it,
exactly because it was not part of ES 5.1. The only fully
ES5.1-compatible way of accessing the prototype chain is
`Object.getPrototypeOf` for reading.
However, ES2015 defines `Object.setPrototypeOf` for rewriting the
prototype chain, and JerryScript has now an ES2015 subset profile.
So, this commit adds its implementation to JerryScript.
Note, this commit does _not_ add `Object.prototype.__proto__`,
since that is in the Annex B of ES2015 specification, which is
optional for non-web-browser hosts.

Since the project is now hosted at the JS Foundation we can move to unified copyright notices for the project.
Starting with this commit all future contributions to the project should only carry the following copyright notice (except for third-party code which requires copyright information to be preserved):
"Copyright JS Foundation and other contributors, http://js.foundation" (without the quotes)
This avoids cluttering the codebase with contributor-specific copyright notices which have a higher maintenance overhead and tend to get outdated quickly. Also dropping the year from the copyright notices helps to avoid yearly code changes just to update the copyright notices.
Note that each contributor still retains full copyright ownership of his/her contributions and the respective authorship is tracked very accurately via Git.
