* init commit, with initial tests for from_param and fields __set__ and __get__, and some additions to from_buffer and from_buffer_copy

* added the rest of tests and patches. probably only a first draft.

* removed trailing spaces

* replace ctype with ctypes in error messages

* change back from ctypes instance to ctype instance

Pauli Virtanen 2d1653aa43 [3.6] bpo-10746: Fix ctypes PEP 3118 type codes for c_long, c_bool, c_int (GH-31) (#3241)
Ctypes currently produces wrong pep3118 type codes for several types.
E.g. memoryview(ctypes.c_long()).format gives "<l" on 64-bit platforms,
but it should be "<q" instead for sizeof(c_long) == 8

The problem is that the '<>' endian specification in the struct syntax
also turns on the "standard size" mode, which makes type characters have
a platform-independent meaning, which does not match with the codes used
internally in ctypes.  The struct module format syntax also does not
allow specifying native-size non-native-endian items.

This commit adds a converter function that maps the internal ctypes
codes to appropriate struct module standard-size codes in the pep3118
format strings. The tests are modified to check for this.

Serhiy Storchaka 0834905d9b [3.6] bpo-13617: Reject embedded null characters in wchar* strings. (GH-2302) (#2462)
Based on patch by Victor Stinner.

Add private C API function _PyUnicode_AsUnicode() which is similar to
PyUnicode_AsUnicode(), but checks for null characters..

Benjamin Peterson 6d999803a0 remove long double from ctypes value union
It is unused. It also forces a 16-byte alignment, which creates problems because
Python's allocator only uses 8-byte alignment.

Victor Stinner e33797b686 ctypes: fix CThunkObject_new()
* Initialize restype and flags fields to fix a crash when Python runs on a
  read-only file system
* Use Py_ssize_t type rather than int for the "i" iterator variable
* Reorder assignements to be able to more easily check if all fields are
  initialized
