python: Fix build in certain cases.
* lang/python/setup.py.in: Prepend the Python build dir to the list of
include directories so that it takes precedence over any other include
directory.
--
Fixes the build in case an older 'gpgme.h' is installed and is picked
up by the compiler when compiling the Python module.

* tests/gpgsm/Makefile.am: Likewise.
--

Now that the daemons sockets are no longer created in the GNUPGHOME,
we cannot rely on cleaning the build directory to make sure they are
shut down.  Therefore, we explicitly kill any running daemons when
creating the test environment.

python: Read gpg-error.h using the pre-processor
* lang/python/setup.py.in: Read gpg-error.h using the pre-processor.

--

The libgpg-error may be installed in multilib configuration in which
there is a wrapper header at /usr/include that includes the actual
header at /usr/include/*. This causes invalid errors.i generation.

Let the pre-processor extract the header content instead reading it
explicitly.

python: Remove usage of PYTHON_VERSIONS
* configure.ac: Remove PYTHON_VERSIONS subst.
* lang/python/Makefile.am: Use basename of python as builddir prefix.
* lang/python/tests/run-tests.py: Likewise.

--

Two variables needs be at sync PYTHONS and PYTHON_VERSIONS, these may go
out of sync in some cases, for example in Gentoo where default python is
3.4 we get:

PYTHON='/usr/bin/python2'
PYTHONS='/usr/bin/python /usr/bin/python2'
PYTHON_VERSIONS='2.7 3.4'

We can use the basename of the python interpreter to achieve similar
effect without having to sync indexes between these two variables.

python: simplify build, some fixups
* lang/python/gpg/version.py.in: Rename to lang/python/version.py.in.
configure.ac: Generate version.py.in in lang/python.
* lang/python/MANIFEST.in: Include version.py explicitly.
* lang/python/gpg: Rename to 'src'.
* lang/python/Makefile.am: Do not copy source files, do not use absolute
directories, support lib64 in uninstall, clean also dist directory, use
symlink for gpg src.
* lang/python/setup.py.in: Use builddir, copy sources into builddir,
copy version.py into module.
--

Simplify build to symlink the gpg sources into builddir instead of
copying. This requires handling of version.py as generated file.

In addition apply some cleanups: Drop the absolution pathes, clean the
dist directory as well, support lib64 for sitelib at uninstall.

python: Extend SWIG gpgme_{sub,}key with a __repr__ method.
* 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.

python: Remove the -builtin flag for SWIG.
* lang/python/setup.py.in: Call SWIG without the builtin flag.
--

The SWIG documentation
<http://www.swig.org/Doc2.0/Python.html#Python_nn28> leaves the
impression that -builtin is solely for increasing performance:

    New in SWIG version 2.0.4: The use of Python proxy classes has
    performance implications that may be unacceptable for a high-
    performance library. The new -builtin option instructs SWIG to
    forego the use of proxy classes, and instead create wrapped types as
    new built-in Python types. When this option is used, the following
    section ("Proxy classes") does not apply. Details on the use of the
    -builtin option are in the Built-in Types section.

While not wasting CPU cycles is good, it also prevents Python code being
written in the wrapper itself. That, however, may be useful to make it
easier to extend the wrapper.

python: Call SWIG_NewPointerObj rather than SWIG_Python_NewPointerObj.
* 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.
