Python 2 never checked for I/O error when reading .py files and
thus could mistake an I/O error for EOF and create incorrect .pyc
files.
This adds an check for this and aborts on an error.
By spec, the "long double" in _PyGC_Head requires the union to always be 16-byte
aligned. However, obmalloc only yields 8-byte alignment. Compilers including GCC
8 are starting to use alignment information to do store-merging. So, the "long
double" needs to be changed to a simple "double" as was long ago done in Python
3 by e348c8d154. For 2.7, we need to add some
dummy padding to make sure _PyGC_Head stays the same size.
glibc is deprecating libcrypt in favor of libxcrypt, however python assumes
that crypt.h will always be included. This change makes the header inclusion
explicit when libxcrypt is present on the system.

Modify the code to use ncurses is_pad() instead of checking WINDOW
_flags field. If your platform does not provide the is_pad(), the
existing way that checks the field will be enabled.
Note: This change does not drop support for platforms where do not
have both WINDOW _flags field and is_pad().

Based on commit 5c4b0d063a by Ned
Deily, which is based on original patches by Brett Cannon and Steve
Dower.
Remove also the private _Py_svnversion() function and SVNVERSION
variable.
Note: Py_SubversionRevision() and Py_SubversionShortBranch() are
unchanged, they are part of the public API.
Also document that using the dedicated functions to delete items is
preferred. Using PyObject_SetAttr/String() and PySequence_SetItem/Slice() for
deletion is deprecated.
This changes the main documentation, doc strings, source code comments, and a
couple error messages in the test suite. In some cases the word was removed
to fix the grammar.
