Fast mode access arrays must be converted back to normal if the array hole count reaches the limit during the initializtaion.

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.

The "super prop ref" flag is incorrectly used at multiple expressions
as it was only cleared if there was an assignment operation.

Since fast access mode arrays can be part of the prototype chain these objects must be handed separately.

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.

Garbage collection can create new free blocks in the heap structure as
it releases memory, so the previous block needs to be looked up again
if a GC happens during a realloc.

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.

This patch extends jmem functionality by adding a realloc function.
This opens up other paths of optimization which can result in smaller
peak memory usage and faster execution times, due to not having to
duplicate memory when we need to extend blocks.

* Added jerry-libm single-source build.
* Improved the `srcmerger.py` script to correctly handle the line numbering.

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.

This patch unifies the recursion limit checking for RegExp, function call and JSON as well.
Until now the limit was only a counter which was increased/decreased at certain points.
This counter has been substituted with a numeric limit which allows to restrict the stack usage.
