This patch is the second milestone of the implementation of this new language element.
Supported:
- Single class inheritance
- Functionality of 'super' keyword
- Implicit constructor in class heritage
- Specific behaviour while extending with the built-in 'Array' or '%TypedArray%' object
- Abstract subclasses (Mix-ins)

Clang 6 is more picky about implicit conversions and complains
about loss of presicion and/or change of signedness.

This patch allows to add further options flags to `lexer_expect_object_literal_id` to handle unique behaviors more easily
also substitutes `PARSER_IS_CLASS` flag hence it is removed.

Initializing a property with a constant is frequent in object initializers.

Binary operations are much faster with literal arguments.
The byte immediates are still kept for other cases, e.g. array declarations.

* Replace JERRY_JS_PARSER feature guard with JERRY_DISABLE_JS_PARSER
All feature guards of jerry-core are deciding about the inclusion
or exclusion of a feature based on the state (defined or undefined)
of a macro -- except for the JS parser guard, which requires
`JERRY_JS_PARSER` to be defined with a value of either 0 or 1. This
has some issues:
- The engine cannot be built with a "clean" compiler invocation,
i.e., without any `-D` command line macro definitions. This is
painful for targets that must use a different build system from
the project's own python/cmake-based one.
- Some build systems in targets and even some code in jerry-code
are already confused about the different semantics of
`JERRY_JS_PARSER`, and simply define it without a value and make
decisions based on the macro being simply defined or not.
This patch renames the guard to `JERRY_DISABLE_JS_PARSER` and makes
use of it in jerry-core based on its state, not based on its value.
As obvious from the guard name, the default for the JS parser is
that it is included in the build.
The patch also touches those targets in the repository that
explicitly defined the original macro (correctly or incorrectly).
* Make cppcheck verbose
Cppcheck can be quite slow sometimes, especially on Travis CI,
which has a "10 mins without output means failure" rule. As the
code base of the project grows, we start to undeterministically
fall over that limit. Thus, this PR makes cppcheck verbose to
ensure that it keeps Travis CI continuously fed with output.

Currently we keep all local variables in the scope chain as long as
a nested function is alive. These variables consume memory although
several of them are never used. This patch focuses on removing those
unused ones whose can be detected at parsing time.

Remove the parser so we can save space if we are
only interested in running snapshots.
Removing the parser enables the snapshot execution.

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.

The fact that the JS parser had been developed as a separate
component for a while is still visible from some macros that mirror
things from JRT. This patch removes those duplicates and makes the
JS parser rely on jrt.h. (The removed macros are: `PARSER_DEBUG`,
`PARSER_INLINE`, `PARSER_NOINLINE`.)

The number of delete opcodes is reduced to two from six. The
range of numbers which can be included in the byte code is
doubled from (-127,127) to (-256,256).
