(cherry picked from commit 86082c22)

Fix an unlikely memory leak on conversion from string to float in the
function _Py_dg_strtod() used by float(str), complex(str),
pickle.load(), marshal.load(), etc.

Fix an unlikely memory leak in _Py_dg_strtod() on "undfl:" label:
rewrite memory management in this function to always release all
memory before exiting the function. Initialize variables to NULL, and
set them to NULL after calling Bfree() at the "cont:" label.

Note: Bfree(NULL) is well defined: it does nothing.

(cherry picked from commit 9776b063)

Fix a reference leak in _bufferedreader_read_all():
_io.BufferedIOMixin.read() leaks a reference on 'data'
when it reads the whole file content but flush() fails.

Fix a reference leak in json if parsing a floating point number fails.

If PyOS_string_to_double() fails in _match_number_str():
decrement numstr ref counter.

Fix reference leaks in _hotshot.LogReaderType on PyTuple_New() failure.

The s_get() function leaks the result variable on low memory.
Partially backport commit 19b52545
to fix it.

Fix linuxaudiodev.linux_audio_device() error handling:
close the internal file descriptor if it fails to open the device.

Use test_support.TEST_HTTP_URL (pythontest.net) instead of http://www.example.com/.

Fix off-by-one bug in cPickle that caused it to use uninitialised memory on truncated pickles read from FILE*s.

out-of-memory cases. Thanks to Charalampos Stratakis.
