Improve the QByteArray implementation

The available constructors for QByteArray are now:
bytes, bytearray, and QByteArray, unicode is not
accepted anymore.

Also the concatenation is now possible between QByteArrays.

Even though is not possible to initialize a QByteArray
with an unicode, we include the possibility to compare it with
one (Compatibility with PyQt).

The __repr__ and __str__ are now properly working.

There seemed to be a confusion regarding data types between
Shiboken, Python2 and Python3 related to bytes,
so now the structure is based on the flag SBK_BYTES_NAME,
which is define as "bytes" for Python3 and "str" for Python2.

Many tests were modified to properly handle string,
using the `py3kcompat` module.
