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 adds posibility to supervise the VM call stack to avoid aborts/crashes due to the recursion calls.

This patch is the proper fix for #2667, since #2269 did not fix the problem entirely.

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 substitutes all binary lvalue operators with an assigment + the corresponding binary operator.
E.g. A += (expression) is pasred as A = A + (expression).
Due to this replacement, all the related binary lvalue CBC opcodes can be removed.
Also the arithmetic related VM instructions can put their result directly onto the stack, since no more checking is needed.

Currently it evaluates the given expression in the context of the top most stack frame.
The expression should access to any variables and arguments that are in the scope chain.
Implement the eval_at request with the level of the scope chain as a further argument.

It supports to list the scope chain of the current execution context and see
which variables are available.

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)

'jerry_merge_snapshots' should not modify the input snapshots. Updated the

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.

`FILE_PATTERNS` is a space-separated list, in contrary to what is
suggested by its documentation. The pattern `*.h, *.c` does not
match header files but files with `.h,` extension only. Rewriting
the current comma-separated pattern makes Doxygen actually process
header files. However, it also reveals several hitherto hidden
issues (mostly missing documentation) in the code. This patch fixes
some of these documentation problems (and lists the files with
outstanding issues in a 'backlog').

There are some leftover global functions in the code that are not
referenced at all anymore. These functions are removed by this
patch.
There are also some global functions that are only used in their
own modules. These functions are made static by this patch.

The removed flag can be substituted with the combination of two existing ones.

Only the global object bound to the root node of the lexical environment
tree does not have a provideThis flag, and ecma_op_implicit_this_value()
falls back to the global object. Hence we get the same effect regardless
of provideThis.

* Rewritten 128-bit integer "type" to use two 64-bit ints (they are
enough), and made it a proper struct instead of an array.
* Rewritten all single-bit shift loops to multi-bit shifts with the
help of CLZ, and used `__builtin_clzll` where available.
* Simplified (and documented) 128-bit DIV10 operation.
* Renamed 128-bit integer handling macros to use simpler names.
(And removed unused macros that were laying around.)

When the `jerry_substring_to_utf8_char_buffer` was called
with direct strings the assert incorrectly assumed that the
string is a ref counted string and tried to access the
refcount value resulting in a failed assert.
Added direct string check for the underlying implementation
and created a test case for such simple string.

As a result of earlier developments, there remained no other
instatiations of the `ALLOC`, `DEALLOC`, and `DECLARE_ROUTINES_FOR`
templates. So, it's simpler to write the alloc/dealloc routines
directly for `ecma_number_t` as well.

`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.

In the `ecma_string_get_chars` method
the contents of a direct string is accessed incorrectly.
It tries to extract the magic string id from the
string pointer but the direct string does not need
this step.

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.
