[Serhiy Storchaka]

PR 4067 fixes following issues when unpickle on Unix or in binary mode files written with protocol 0 in text mode on Windows:

* ints were unpickled as longs by cPickle.
* bools were unpickled as longs by cPickle and as ints by pickle.
* floats couldn't be unpickled by cPickle.
* strings couldn't be unpickled by pickle.
* instances and globals couldn't be unpickled. And error messages were confusing due to invisible \r.
* pickles with protocol 0 containing Unicode string with \x1a couldn't be unpickled on Windows in text mode.
