Fix out of bounds read in long_new() for empty bytes with an explicit base. int(b'', somebase) calls PyLong_FromString() with char* of length 1 but the function accesses the first argument at offset 1. CID 715359

Fix null pointer dereferencing in structmember.c PyMember_SetOne() for T_CHAR. _PyUnicode_AsStringAndSize() can return NULL without touching the len argument. Also remove unnecessary PyUnicode_Check(), _PyUnicode_AsStringAndSize() performance the test again. CID 486815

Issue #15895: my analysis was slightly off. The FILE pointer is only leaked when set_main_loader() fails for a pyc file with closeit=0. In the success case run_pyc_file() does its own cleanup of the fp. I've changed the code to use another FILE ptr for pyc files and moved the fclose() to PyRun_SimpleFileExFlags() to make it more obvious what's happening.

Issue #15895: Fix FILE pointer leak in PyRun_SimpleFileExFlags() when filename points to a pyc/pyo file and closeit is false.

MERGE: #15676: mmap: add empty file check prior to offset check <- Previous patch was incomplete (fix 2)

constructing infinities. This is done for backwards compatibility
with decimal.py: Infinity coefficients are undefined in _decimal
(in accordance with the specification).

Fixed reference leak in error branch of _bufferedreader_read_all(). The variable data can contain a bytes object but it wasn't cleaned up when PyList_New() failed. CID 715364

Fixed memory leak in error branch of object_repr which may leak a reference to mod when type_qualname returns NULL. CID 715371

Fixed memory leak in error branch of parsestrplus. CID 715374 Variable s going out of scope leaks the storage it points to.

Also adds tests to verify the documented behavior (which is probably a bug, as
indicated in the added comments).
