Direct strings are a new type of direct ecma-values (no memory allocation
is needed for encoding them) in JerryScript. Currently magic strings,
external magic strings and uint values are encoded as direct strings.
The constant pool of JerryScript byte-code is changed to hold ecma-values
rather than cpointers to support direct strings.

Aborts are similar to exceptions except they are not caught by catch
and finally blocks. Callbacks should honor aborts as well and return
them without processing them. Aborts are never thrown by JavaScript
code.
In the future certain events such as out-of-memory condition may
also throw aborts.

This patch adds two new string concatenation functions:
ecma_append_chars_to_string and ecma_append_magic_string_to_string
The former appends a cesu8 byte array and the latter appends a magic string
to the end of an ecma-string. These two free (dereference) their ecma-string
argument, and this change is also applied to the original ecma_concat_ecma_strings
function which simplifies string handling in most cases.

NuttX and artik053 build - compiling with strict Werror=conversion - fail when jerry-debugger option is enabled.
This patch based on #2007, because most of them are fixed earlier within that PR, but it was closed before the land.

Fixes issue #2073, which introduced an error caused by Date.parse()
The problem was that the function didn't properly check if there was a ':' after the hours.
If any UTF8 character was inserted there which got decoded into multiple characters, it caused the pointer to point at a wrong character.

This change frees up the error bit in ecma_value_t, which allows
to define 4 more value types (e.g. symbols). To keep API
compatibility we introduce a box for values with error flag.

* 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.
