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.

The length*sizeof(ecma_value_t) may overflow on 32 bit systems which
cause a memory corruption when the values are filled.
Fixes#2182.

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.

This patch removes all ecma_make_simple_value calls to make the code more easy to understand.
Also removes the type ecma_simple_value_t which improves the performance in related code paths by calculating the value of new ecma_value_t is no longer needed.

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.

The built-in `print` is removed from jerry-core, but an external
`print` implementation is added to jerry-main. From now on, all
embedders of the engine have to implement their own `print` if they
need such a functionality.
For printing results in REPL mode of jerry-main, the external
`print` handler is called directly instead of looking up the `print`
function registered into the global object. (The two are the same,
but the indirection is not needed anymore.)
Because jerry-core does not contain `print` anymore,
`jerry_port_console` is removed from the port API. The default port
is updated, i.e., the implementation of `jerry_port_console` is
removed. Additionally, all references to `jerry_port_console` in
jerry-main are replaced by `printf`.
Speculatively, `jerry_port_console` is also removed from all
non-default targets. Most targets implemented it for the sake of the
engine only; in those targets the removal was trivial. Where the
function was called from the embedder application as well, the
calls were replaced with equivalents (e.g., `printf`, `printk`).
NOTE 1: This is a breaking change!
NOTE 2: This patch still leaves several targets without a JS `print`
implementation.

Currently, `lit-magic-strings.inc.h` is manually maintained. This
has several drawbacks:
- keeping the list of magic strings sorted first by length then
alphabetically is error prone,
- it is easy to leave unused magic strings in the list by accident
(e.g., `LIT_MAGIC_STRING_JERRY_UL` is defined as a magic string
but not used anywhere in the code) and,
- it is very hard to add `CONFIG_DISABLE_*_BUILTIN` guards to the
list, even though there are several magic strings, which are used
in some of the configurations only (e.g, "setPrototypeOf" is used
in ES2015 only).
To ease the maintenance of magic strings, this commit moves the
definition of magic strings to a config file
(`lit-magic-strings.ini`), and adds `tools/gen-magic-strings.py` to
generate the `.inc.h` file from this config file and from the use
cases of the strings in the code.
- The magic strings in the config file can appear in any order, the
generator will ensure that they are correctly sorted.
- The generator skips those definitions that are not used anywhere
(and emits a warning to signal that such definitions can be
removed).
- The generator applies the same guards to the definitions in the
`.inc.h` file as found in the code around the use of the strings
to optimize for size.
The commit also changes some builtin-related `.inc.h` files by
adding guards that don't affect functionality but improve the
results of the generator.
To ensure that the invocation of the generator does not get
forgotten, the commit also adds `tools/check-magic-strings.sh` and
binds it into the testing infrastructure.

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.

For negative out-of-range time values, ecma_date_year_from_time
fell into an infinite loop. (Moreover, for positive out-of-range
time values, it returned an incorrect year.) This patch fixes the
helper to return NaN in these cases (and ensures that its call
sites are prepared for NaN values).
Fixes#1657.
