This patch improves the ecma_integers_values multiplication by checking if the multiplier or multiplicand is power of 2.
If it is it uses right shift instead of multiplication.

Building with all-in-one and enabled debugger caused

By moving the _XOPEN_SOURCE macro to a generic place
we make sure that the required sleep functions are

Until now, the engine's feature set was configurable either via
`CONFIG_*` macro guards defined individually on compiler command
line or via profiles (which are text files listing macro guards,
picked up by the cmake build system and turning them into compiler
command line options). And the features under profile control are
all enabled by default (i.e., all macros are `CONFIG_DISABLE_*`).
This causes a maintenance issue when new features are added to the
engine, because the disabling macros have to be added to all
profiles that don't include the new features. This can even cause
"compatibility break" for applications that embed JerryScript but
don't use the cmake or the python build system, because then
profiles are unavailable and all feature disabling guards have to
be explicitly passed to the compiler. (I.e., if such an application
wants to use the ES5.1 feature set, it must define all the ES2015
disable macros; if the engine is developed further and a new ES2015
feature gets implemented, then the new feature will sneak into the
application's binary unless its own build system is changed to add
the new feature guard.) Even the in-repo example Curie BSP target
seems to have suffered from this maintenance problem.
This patch introduces two new grouping macro guards that enable the
disabling of all ES5.1 builtins and all ES2015 features. As the
grouping logic is in config.h, the maintenance of non-cmake-based
build systems becomes easier (and there is no change for the python
and cmake-based build systems).

Added two new api functions:
* jerry_parse_and_save_function_snapshot
* jerry_load_function_snapshot_at
The jerry_parse_and_save_function_snapshot function allows
creating snapshots from snapshot arguments and body source.
The jerry_load_function_snapshot_at function enables loading
back functions from a given snapshot as a JS function object.

* 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.

- The context reset request message can be sent anytime from a client.
- After the message received the engine will call the cleanup and init
when in the source waiting mode (which means the currently processed file will be executed).
- After the reinitialization is done, the engine will wait
for a new client connection(rest of the work is the client's responsibility).
