Robert Sipka de1912f6f8 Improve the string descriptor.
Separate the utf-8 and ascii strings.
In case of ascii strings the size is equal to the length, so we able to store this information
in the string descriptor instead of using the string header to store it.

László Langó 2a5468a2ac Improve double to string conversion
Added errol implementation. Fixed '3d-raytrace.js', because
the new algorithm has better precision and also reduce the
code size.

Robert Sipka 19b972b8eb Check whether the aligned pointers value of the internal properties can be stored directly in ecma_value_t.
Those internal properties which have a primitive value field or where the property value type
is an ecma_object_t ptr were checked earlier.

Akos Kiss 27682017e9 Remove unused internal functions
The internals have surprisingly large number of unused functions at
surprising places. This patch cleans them out to make maintenance
easier and to prevent dead code having effect on future decisions.

The patch intentionally does not try to clean up public API but
focuses on internal modules only that are/should not be reachable
from "outside".

However, unit tests do access private API, thus tests of literal
storage had to be adjusted.

Zoltan Herczeg 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.

Akos Kiss 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`.

Akos Kiss 7a07e55411 Unify the naming scheme of all header defines
There have been several renamings of header files but the
ifndef/define/endif preprocessor directives did not always follow

scheme). This patch gets all headers aligned with the style of the

Akos Kiss 25b0750756 Fix problems arising from incorrect use of various size types
E.g.,
* `ssize_t` was used where `lit_utf8_size_t` or `jerry_api_size_t`
  would have been correct,
* `lit_utf8_size_t` was used where `ecma_length_t` would have been
  correct.

Note, the patch also includes internal and public API changes:
* `ecma_string_to_utf8_string` does not return negative value if
   output buffer is not large enough to contain the string; the
   buffer is expected to be large enough. (`ecma_string_get_size`
   can be used to retrieve the required size.)
* `jerry_api_string_to_char_buffer` adapts the same logic (and
  `jerry_api_get_string_size` can be used to determine the
  required size of the buffer).

Akos Kiss 0d7ea70b41 Eliminating doxygen warnings by fixing the documentation
* Fix "end of file while inside a group" doxygen warnings.

* Fix "unknown command" doxygen warnings caused by incorrect
  argument references. Instead of `@foo`, `@a foo` is the proper
  format.

* Fix "unknown command" doxygen warnings caused by incorrect
  parameter direction specifications. Instead of `@in`, `@out`,
  and `@in-out`, `[in]`, `[out]`, and `[in,out]` are the proper
  formats.

* Wrapping special characters in quotes to avoid doxygen
  confusion. Raw pipe, semicolon, dot, backslash, etc. characters
  can drive doxygen into various misinterpretations and warnings.
  E.g.:
  ```
  End of list marker found without any preceding list items
  Found unknown command
  ```
  Putting quotes around such text snipets eliminates the errors.

* Fix the documentation of `ecma_builtin_global_object_print`. Raw
  <> and \ sequences confused doxygen in various ways (it tried to
  interpret them as XML tags and doxygen commands).

* Fix "ignoring title that does not match old title" doxygen
  warnings. At some places, the group titles were out of sync, at
  others, the group names were incorrect.

* Fix "parameters are not documented" doxygen warnings. Fixing
  various typos in the inline parameter documentations (`/*`,
  `/**`, `/** <`, and `/**>` are all considered incorrect, the
  right format is `/**<`).
