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.

79bc5d0220 Bugfixes related to low memory conditions.
- Bugfix for removing property hashmap in ecma_gc_run.
 - Fixed bug in ecma_create_property() caused by the new property pair allocation.

0a32c97755 Rework literal storage.
The new literal storage keeps ecma strings rather than having a
custom string implementation which duplicates the string management
routines. Conversions between string implementations are eliminated
which improved the performance by 4%.

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.

5c852ab6fb Optimize LCache operation.
The cache stores only real properties now, because storing NULLs has
little benefit according to tests. Since only real properties are
stored now, there is no need to create real references to objects
and property names, which reduces the keeping of dead objects after
garbage collection.

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.

92bb551d45 Change 'mem' namspace to 'jmem'
The 'mem_' prefix is too general, so it might clash with
symbols in other libraries. Renamed the directory, file,
funtion and type names.

5ecf83ee8a Change internal property values of built-in primitive objects (namely Number,
String, Boolean) to use ecma-values. When the value of a Number object is
a small integer number, this change reduces the memory consumption, since no
double is allocated.

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.

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`.

d190ca44ae Storing byte code size in the byte code header. This reduces the
memory consumption, because the new allocator uses less memory if
the size as available when a block is freed. Snapshot generation
is also simplified.
