Rewrite PyUnicode_Append(); unicode_modifiable() is more strict
* Rename unicode_resizable() to unicode_modifiable()
* Rename _PyUnicode_Dirty() to unicode_check_modifiable() to make it clear
that the function is private
* Inline PyUnicode_Concat() and unicode_append_inplace() in PyUnicode_Append()
to simplify the code
* unicode_modifiable() return 0 if the hash has been computed or if the string
is not an exact unicode string
* Remove _PyUnicode_DIRTY(): no need to reset the hash anymore, because if the
hash has already been computed, you cannot modify a string inplace anymore
* PyUnicode_Concat() checks for integer overflow
