* lang/python/gpgme.i: ignore HAVE_CXX11 in SWIG interface
--
If there are two distinct builds (a) and (b) of gpgme which both build
python bindings, and build (a) also happens to build the C++ bindings,
then the generated gpg/gpgme.py file from build (a) will not be usable
with the .so generated in build (b), despite them being exactly the
same, and having nothing to do with C++.
In particular, it will fail with:
-----------
File "…/gpg/__init__.py", line 99, in <module>
from . import core
File "…/gpg/core.py", line 10, in <module>
from . import gpgme
File "…/gpg/gpgme.py", line 152, in <module>
HAVE_CXX11 = _gpgme.HAVE_CXX11
AttributeError: module 'gpg._gpgme' has no attribute 'HAVE_CXX11'
-----------
By asking SWIG to ignore this definition, we stabilize the generated
.py and the .so, ensuring that they are more cleanly interoperable.
* src/gpgme.h.in: Obsolete "class" also for Python.
* lang/python/gpgme.i: Silenece a swig warning. Silence a gcc
warning.

* lang/python/gpgme.i: copied signature from gpgme.h and defaulted the
value to SEEK_SET.
* lang/python/tests/t-data.py: Added a test for no second argument
--
Having to import the os package when wanting to read a Data object is a
slight annoyance. With SWIG, we can define default parameters. This
change defaults the whence argument to SEEK_SET which is how StringIO
and BytesIO behave.

* lang/python/gpgme.i: Added a genericrepr macro and use it for
gpgme_key, gpgme_subkey, and gpgme_key_sig.
--
To look nicer in Python's REPL.
We define a generic __repr__ as a SWIG macro and use that to extend some
defined SWIG objects.
The alternative would have been to write a custom __repr__ function for
each class but that would need to be changed everytime the object's
structure changes. The bindings should be easy to maintain, I guess.
This comes at the expense that the reprs are now relatively long and
contain, for example, both keyid and fingerprint.

* lang/python/gpgme.i (pygpgme_wrap_gpgme_data_t): Provide a "self"
variable for SWIG_NewPointerObj and call SWIG_NewPointerObj rather than
SWIG_Python_NewPointerObj.
--
SWIG_Python_NewPointerObj seems to be an implementation detail, because
SWIG's documentation does not mention that function at all. In fact,
SWIG_NewPointerObj is a call to SWIG_Python_NewPointerObj with the first
parameter being either NULL or the "self" variable, depending on whether
SWIG is called with the -builtin flag. So far, the first parameter was
hard-coded to NULL. This change also hard-codes it to NULL but makes
it more explicit. The benefit is that the documented function is being
used and that compilation works regardless of the -builtin flag.

* lang/python/gpgme.i: Added gpgme_op_keylist_start with defaults
* lang/python/tests/t-keylist.py: Added tests for default parameters
--
To increase the ease of use, op_keylist_start
parameters default to sensible values.
The empty string matches all keys.
We assume that the user wants to retrieve public keys most of the time,
so we default to public keys rather than secret keys.
