Optimize string concatenation. (#2141)
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.

e83de3accd Remove ecma_simple_value_t and refactor ecma_make_simple_value (#2135)
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.

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.

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the codebase with contributor-specific copyright notices which have a higher maintenance overhead and tend to get outdated quickly.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.

fd98d649b6 Remove several internal property types for primitive objects. (#1399)
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.

dcaec22c0c Major property rework: introducing virtual properties.
Properties are changed to a type and value pair instead of a pointer to an internal
representation. Functions such as ecma_op_object_get_[own_]property do not
return with property pointers anymore.

548b3b98c2 Change return value to ecma_value_t for getting internal properties.
Removing a lot of ECMA_PROPERTY_VALUE_PTR macro calls. The only drawback
is free callbacks for native objects cannot be deleted anymore. Redefining
a free callback is a rare case, so this trade-of is acceptable.

f15e7beadc Remove compact profile.
The standard doesn't defines ECMAScript Compact Profile as a subset of Ecma-262 Edition 5.1.
Profile modes can be added easily like the minimal profile if required.

1726bba184 Create extended objects instead of internal properties.
Several internal properties are removed and directly stored as
part of the object. Faster built-in and JS function processing.

0daeb2f942 Remove string copy
Changed 'ecma_copy_or_ref_ecma_string' to 'ecma_ref_ecma_string'. It does
not copy the string if the maximum number of reference counter is reached,
but bails out with an error like the 'ecma_ref_object' function does.

8c92972b2f Passing less number of arguments to a function is generally faster. So
the three boolean arguments of ecma_create_named_data_property and the
two boolean arguments of ecma_create_named_accessor_property are combined
into one uint8_t argument. On ARM-32 it is preferred to have less than
four arguments, since these arguments can be passed in registers.

c7dcce4fc7 Refactor object property chain to use property pairs. The patch
itself seems a step back, but the primary aim is opening future
optimization opportunities. The list of changes follows:

 - Property is changed to be an abstract type, which has type, flags,
   and a value. It does not have a name anymore and property pointers
   cannot be compressed.
 - Full (32 bit) ecma values can be property values. This allows
   using non-compressed pointers for ecma values in the future.
 - The property chain is not restricted to the same item anymore,
   it can contain hash maps, arrays in the future.

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`.
