[PATCH/RFC] setools: update swig interfaces for swig-2.0.7 (and higher?)

[Sven Vermeulen <sven.vermeulen@siphos.be>]

Hi guys,

In Gentoo, I had to patch the setools package' swig interfaces to build with
the swig-2.0.7 (and probably a few previous ones, version 2.0.4 still seemed
to build the code properly). The patch is fairly large (228 KiB) so I've put
it online for now. However, I'm not sure if this is the right way to fix
things or not.

In any case, the build failures we got were:

../qpol.i:241: Warning 504: Function qpol_module::qpol_module_t(char const
*) must have a return type. Ignored.
../qpol.i:244: Warning 521: Illegal destructor name
qpol_module::~qpol_module_t(). Ignored.

and

qpol_wrap.c:1831:24: error: conflicting types for qpol_module_get_path
../../../libqpol/include/qpol/module.h:69:13: note: previous declaration of qpol_module_get_path was here
qpol_wrap.c: In function qpol_module_get_path:
qpol_wrap.c:1834:3: error: too many arguments to function qpol_module_get_path
qpol_wrap.c:1831:24: note: declared here

I fixed it by changing the constructors/destructor names to the struct name
(as in "typedef struct qpol_module {} qpol_module_t" so the
constructur/destructor uses "qpol_module" rather than "qpol_module_t", and
by introducing %rename() calls for each collision found during the build
process.

The patch is at
http://dev.gentoo.org/~swift/patches/0008-fix_swig_build_failures_bug_430262.patch

If it is the right patch, I hope this saves a few hours of work for the
other developers ;-)

Wkr,
	Sven Vermeulen
