40f7b1c27f Rework usages/naming of configuration macros [part 1] (#2793)
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.

7e3d688e5b Implement the Symbol builtin object (#2601)
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)

93ec226650 Extract binary lvalue operators (#2630)
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.

Cleanup code around JERRY_UNREACHABLEs (#2342)
`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.

65ae949dc3 Add jerryscript-compiler.h public header to cover compiler incompatibilities (#2313)
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.

51e3c4455a Implement direct strings. (#2196)
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.

53cd324179 Rework error to use a global slot to store the error value.
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.

0f4edbe580 Ensure that const and pure function attributes are used properly (#1739)
Some functions were incorrectly marked as const but were pure only
(or not even pure). Some functions were marked as pure but
qualified as const. Some functions were not attributed at all but
qualified either as pure or const. Some functions had attributes
at definition but not at declaration. This commit fixes these
inconsistencies.

0511091e8a Streamline copyright notices across the codebase. (#1473)
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.

9aca0086b9 Doc comment maintenance
Fixed doc comments issues:

* Fixed mistyped param doc comments (`/**<` is OK, `/** <` is not).

* Put special characters (e.g., pipe, backslash, etc.) in quotes, as they can
  confuse doxygen and it will print lots of various warnings. For the sake of
  completeness and consistent style, also quote some special characters in
  re-bytecode.h

* Added missing `@{`s, removed extra `@}`s.

* Turned `/*` comments to `/**<` doc comments.

Ensured same style for doc groups everywhere:

* Where `\addtogroup`, `@{`, and `@}` doxygen commands are used, the order to be
  followed is: license, `#ifndef` guards (in headers), includes, `\addtogroup`
  and `@{`, main code content, `@}`, `#endif` guards (in headers).

* Multiple `\addtogroup`s or multiple `@}`s should be in the same doc comment.

* First `\addtogroup` should be on the very first line of a doc comment, i.e.,
  `/** \addtogroup`.
