Similar to the ecma_op_to_object rework, in this new method we
return directly with the pointer to the ecma string, and we don't
wrap the result into an ecma_value_t

- The structure members have been renamed and the members got more detailed description.
- Updated the usage of the typedarray info structure in all occurrences to use absolute addressing from the underlying arraybuffer pointer.

ES5.1 15.9.1.15 Note1 defines that 24:00 is same as 0:00
of the next day. The spec explicitly doesn't mention that
24:01 should be invalid, but it should be self-evident.
(FireFox and Chrome also refuses times bigger than 24:00)

Here are the following changes:
- The getter and setter methods are callback based now, and we can use
them with the proper typedArray id
- The typedArray set_element and get_element methods are using memcpy now.
- There is a new struct which contains basic informations from typedArray,
and we are using this in most of the prototype methods.
- Eliminated ecma_op_typedarray_set_index_prop and
ecma_op_typedarray_get_index_prop, because these methods
also calculated the same informations which are in the new
struct, so we use the new method instead.

The implementation was incorrect for negative years and years bigger than 9999.
-1 was 000/ because the negative (year%10) was added to '0' character, years
bigger than 9999 was truncated to 4 digits.
ES5.1 15.9.1.15.1 defines extended years format with 6 digits, but toString()
and toISOString() sections don't mention anything about extended years. ES6
20.3.4.3 already clarifies that Date.prototype.toISOString() should use this
extended year format if it is necessary.
Changes:
- Date.prototype.toString() uses 4 digits for years by default, 5 or 6 if it
is necessary and put '-' sign for negative years, no sign for positive years.
Date.prototype.toString() was implementation dependent until ES9, but ES9
already specify exactly this format.
- Date.prototype.toISOString() uses fixed 4 digits for years 0 - 9999,
otherwise sign + 6 digits (extended years).
- Tests added for corner cases.

ES5.1 15.9.4.2 specifies that Date.parse (string) has to accept
at least Date Time String Format: YYYY-MM-DDTHH:mm:ss.sssZ. But
the spec allows implementation-specific fallbacks. Additionally
ES5.1 15.9.1.15.1 specifies Extended years format, but isn't
explicitly required to be accepted by Date.parse. But ES6 already
clarified that Date.parse has to accept extended years format too.

In case of TypedArrays which were constructed with an ArrayBuffer
the `slice` method incorrectly added the `byteOffset` value of
when the elements were copied.
There is no need to add the `byteOffset` value for the ArrayBuffer's
contents pointer as it is already added by the `ecma_typedarray_get_buffer`
call.

This patch introduces several changes conntect to ecma-strings:
- Extend the size of the reference counter to 28 bytes from 13
- Extend the size of the string hash to 32 bytes from 16 to use the extact FNV-1a hash
- Introduce ECMA_STATIC_STRING_FLAG to reduce the number of string ref/derefs for static strings.
- Introduce ECMA_STRING_CONTAINER_ASCII_STRING to store run-time allocated ASCII strings more efficiently
- Remove ECMA_STRING_CONTAINER_LIT_NUMBER to half the storage size of the parsing time allocated floating point numbers
- Rework the global number storage, to store only the floating point numbers
- Optimize the lookup in the global number/string/symbol tables via reduce the number of NULL checks during decompressing the next element pointers
- Reduce the code duplication in ecma_concat_ecma_strings and ecma_append_chars_to_string
- Improve ecma_string_get_char with optional arguments to make it more reusable.

This patch removes the ecma_property_descriptor_t structure bitfields and substitutes it with an uint16_t flag field
to reduce the cost of the transformation from/into the ecma_property_flags_t.
Also the is_throw last arguments is embedded to the property descriptor structure during the property defining process to reduce the number of arguments of the function.

ECMA_GET_POINTER is removed from:
- property list iteration
- lexical environment chain iteration
- prototype chain iteration
For all these iteration the compressed pointer can be used to get the elements and only decompressed them if it is necessary.
- Properly guard ecma property hashmap routines
- Remove the redundant NULL pointer check from ecma_create_property
- Remove ecma_gc_get_object_next since it became unnecessary
- Substitute ECMA_{GET,SET}_POINTER with ECMA_{GET,SET}_NON_NULL pointer when we can assume the pointer is not NULL
- Remove ecma_get_object_prototype and ecma_get_lex_env_outer_reference helper function the reduce the number of NULL pointer checks during decompressing the pointers
- Remove ecma_get_named_accessor_property_{getter,setter} helper functions for also reduce the number of NULL pointer check/decompressions
- Remove ECMA_PROPERTY_SEARCH_DEPTH_LIMIT since in ES5 there is no way to create circular prototype chain, and the ES2015 setPrototypeOf method can resolve this error so this check during the property lookup can be eliminated.

The Math.pow implementation calls libm's pow. The ISO C and ES5.1
standards differ on some special cases of pow. jerry-libm is already
ES5.1 conform, but system libm libraries on Linux and Windows aren't.
Math.pow(NaN, +/-0.0) is NaN on Windows and Linux with system libm,
but should be 1.0 according to ES5.1 / 15.8.2.13.
This patch handles this special case in Math.pow instead of calling pow of libm.

The current module implementation resolves module paths relative to the
current working directory, but paths should be resolved relative to the
currently evaluated module/source.
This requires a change in the jerry_port_normalize_path port API
function, so that it also takes the current module path as an argument.
On the engine side, we now also create a module object for the main
script, so that we can properly identify the base path for other
modules.
