There are quite a few configuration macros in the project.
As discussed in the #2520 issue there are a few awkward constructs.
Main changes:
* Renamed all CONFIG_DISABLE_<name>_BUILTIN macro to JERRY_BUILTIN_<name> format.
* The special JERRY_BUILTINS macro specifies the basic config for all es5.1 builtins.
* Renamed all CONFIG_DISABLE_ES2015_<name> to JERRY_ES2015_<name> format.
* The special JERRY_ES2015 macro specifies the basic config for all es2015 builtins.
* Renamed UNICODE_CASE_CONVERSION to JERRY_UNICODE_CASE_CONVERSION.
* Renamed ENABLE_REGEXP_STRICT_MODE to JERRY_REGEXP_STRICT_MODE.
* All options (in this change) can have a value of 0 or 1.
* Renamed ENABLE_REGEXP_STRICT_MODE to JERRY_REGEXP_STRICT_MODE.
JERRY_REGEXP_STRICT_MODE is set to 0 by default.
* Reworked CONFIG_ECMA_NUMBER_TYPE macro to JERRY_NUMBER_TYPE_FLOAT64 name and now
it uses the value 1 for 64 bit floating point numbers and 0 for 32 bit floating point
number.
By default the 64-bit floating point number mode is enabled.
* All new JERRY_ defines can be used wit the `#if ENABLED (JERRY_...)` construct to
test if the feature is enabled or not.
* Added/replaced a few config.h includes to correctly propagate the macro values.
* Added sanity checks for each macro to avoid incorrectly set values.
* Updated profile documentation.
* The CMake feature names are not updated at this point.

This patch contains the base functionalities that the new builtin object requires.
Currently unavailable:
- print (Symbol('foo')) - this features requires the refactor of the print handler function
- Several global symbol based builtin routines (follow up patch)

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)

It is superfluous to maintain multiple globals when the whole
reason of context is to keep them in a single place. It also
simplifies initialization and external context creation a bit.
Also removed unused lcache header includes.

`JERRY_UNREACHABLE`s often signal code structure that could be
improved: they can usually either be rewritten to `JERRY_ASSERT`s
or eliminated by restructuring loops, `if`s or `#if`s. Roughly,
the only valid occurences are in default cases of `switch`es. And
even they can often be merged into non-default cases.
Moreover, it is dangerous to write meaningful code after
`JERRY_UNREACHABLE` because it pretends as if there was a way to
recover from an impossible situation.
This patch rewrites/eliminates `JERRY_UNREACHABLE`s where possible
and removes misleading code from after them.

In general, public headers should not have compiler-specific
constructs but both the core and the port headers have attributes,
which are non-standard. It's better to factor out such constructs
to a common place (a new header) and hide them behind macros, which
can then be defined on a per-compiler basis.
This patch moves the existing definitions of function attributes and
likely/unlikely builtins to the new header. At the same time, it
unifies the names of these attribute defines and where they are
used. Moreover, it touches on jerry-main and removes the uses of
`__attribute__((unused))` entirely and replaces them with the
elsewhere used `(void) ...` pattern.

Unlike normal snapshots, no part of a static snapshot is loaded into
the RAM when executed from ROM. Static snapshots rely heavily on
external magic strings.

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.

With this feature the debugger webIDE and the python client can able to send a source code to the debugger while that is running in wait mode.
This feature can be activated with the --debugger-wait-source switch and the debugger will wait for the source messages.
If every message part are received the debugger will continue the exectuion with the initalized options.

The internal header was a legacy, declared two functions only. One
of them was not used anymore at all, the other was used at a single
call site. Moreover, their documentation was outdated. This patch
removes the header and the related function implementations -- as
well as the temptation to use such internal functions from outside
the library.

Ecma-object have native handle type inside, and binding code could use
type info to validate native handle's type.

Change CONFIG_DISABLE_ES2015_ARRAYBUFFER_BUILTIN to
CONFIG_DISABLE_ES2015_TYPEDARRAY_BUILTIN

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.

Property names were always required a string reference which consumed
a large amount of memory for arrays. This patch reduces this consumption
by directly storing the value part of certain strings.

This change allows easier access to array length which improves
the performance of inserting new items into an array and there
is no need to allocate length strings anymore. The trade-of is
that array length cannot be cached anymore.

and special property types into one group. Also simplify checking
special properties since bit-and operation is not needed anymore.

The algorithm is the following:
* introduced a counter variable, which value can be [0-4]
* if its value is 0, property hashmap allocation is enabled
* JMEM_FREE_UNUSED_MEMORY_SEVERITY_LOW -> decrease the counter
* JMEM_FREE_UNUSED_MEMORY_SEVERITY_HIGH -> increase the number
* if JMEM_FREE_UNUSED_MEMORY_SEVERITY_HIGH happens twice in a row increase the counter to 4
According to the measurements this algorithm provides better runtime results in low memory conditions.

The new code does not use value collections which reduces the argument array size by half.

Instead of allocating a helper object, argument names are appended right
after the arguments objects. This reduces memory consumption and improve
performance as well. In the future this could be further improved by a
bitfield, but that would require a reference to the byte code which
might increase memory consumption in a few corner cases.

Class and value internal properties are always exists for primitive
types (e.g. Boolean, Regex) so they can be stored right after the
object. This improve property access (since internal properties are
searched by a slow linear algorithm) and reduces memory consumption,
since only 8 byte is allocated for these two properties instead of
16 which is the size of a property pair.
