Akos Kiss d0143adc82 Replace JERRY_JS_PARSER feature guard with JERRY_DISABLE_JS_PARSER (#2036)
* 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.
