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.

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

Fix two unlikely reference leaks in _hashopenssl. The leaks only occur in
out-of-memory cases. Thanks to Charalampos Stratakis.

Did you know an API documented as printing the pending traceback would sometimes exit the process?

You do now.

The standard math library (libm) may follow IEEE-754 recommendation to
include an implementation of sinPi(), i.e. sinPi(x):=sin(pi*x).
And this triggers a name clash, found by FreeBSD developer
Steve Kargl, who worked on putting sinpi into libm used on FreeBSD
(it has to be named "sinpi", not "sinPi", cf. e.g.
https://en.cppreference.com/w/c/experimental/fpext4).

Per POSIX, `nice(3)` requires `unistd.h` and `exit(3)` requires `stdlib.h`.

Fixing the test will prevent false positives with pedantic compilers like clang.
