This allows libnl to be built with -std=c99, which prevents the compiler
from using non-reserved identifiers for extensions.

The define was left enabled during development on netlink (and genl)
python swig api. It is a bit annoying in production release so disable
the define.

Currently, setup.py is created by configure in builddir while source
files (.py and .i) reside in srcdir. Adjust paths in setup.py
appropriately to make it possible to perform an out-of-source build.
This is far from perfect but it mostly works. Python files are copied
from srcdir, and swig *.i files are read from there. However, swig
output files are created in srcdir rather than builddir, and distutils
copies '..' literally when constructing '.o' paths. As a result,
'../python/foo.i' would end up being compiled to
'build/temp*/../python/foo.i'.
The alternative would be to copy '*.i' files to builddir before
proceeding with the build, either in Makefile or through creating
additional distutils command.

parameter to nl_cache_resync
Here are a few things I fixed and that provoked a python error.
I canno't answer to this thread but one solution I found while using
the python binding is to iterate over all and filter via python
http://list-archives.org/2013/09/09/libnl-lists-infradead-org/missing-feature-for-retrieving-cached-
address-objects/f/5031600704
Example:
cache = nlrta.AddressCache()
cache.resync()
for i in cache:
print ("item", i ) # then you can filter here

The message receive callback handler in the netlink api processes
the result object from the python callback. It used PyArg_ParseTuple()
to get the value, but this does not work as intended (see ref [1]).
Instead check the type and convert it accordingly.

The callback functionality only worked for regular Python
functions. With this patch it also allows the callback
to be a class method (bounded or unbounded) as show in
example below.
class test_class(object):
def my_callback(self, msg, arg):
print('handling %s' % str(msg))
s = netlink.core.Socket()
testobj = test_class()
netlink.capi.py_nl_cb_set(cb, netlink.capi.NL_CB_VALID,
netlink.capi.NL_CB_CUSTOM,
test_class.my_callback, testobj)
netlink.capi.py_nl_cb_err(cb, netlink.capi.NL_CB_CUSTOM,
test_class.my_callback, s)

The initial commit adding netlink callback handling also introduced
memory leak issue. The python callback info was stored in an allocated
structure, but that was never freed.
Only exposing nl_cb_alloc() as is. nl_cb_get() is removed as it is
not very useful to use reference counting mechanism. Python uses
that itself internally. To deal properly with Python callback info
the function nl_cb_put() and nl_cb_clone() have a custom wrapper
taking care of Python reference counting.
This commit also adds a Callback python class using the netlink
callback functions.

genlmsg_parse() function is handled similar to nla_parse_nested() so
it returns tuple with error code and dictionary of parsed attributes.

added support functions to access the netlink attributes and use
custom callback handlers. Most is wrapped as is, but there are
a couple of special cases handled.
1) void *nla_data(struct nlattr *);
The return value is changed to a Python byte array so it includes
the lenght of the data stream.
2) int nla_parse_nested(...);
This returns a tuple (err, dict). 'err' is the error code and 'dict'
is a dictionary with attribute identifier as key and value represents
a struct nlattr object.
3) macro nla_for_each_nested()
Provide nla_get_nested() which returns a Python list of struct nlattr
objects that is iterable.
4) allocate struct nla_policy array
Provide nla_policy_array() function that allocates consecutive space
in memory for struct nla_policy array entries. Each entry is put in
a Python list so the entry fields can be modified in Python. This
array object can be passed to the nla_parse_nested() function.

With this change you can still set do modifications of
Links and then to change to pass the changes to the
kernel. But it additionally enables you to interact
with this part of libnl-python in a more pythonic
way. Instead of:
eth0 = links['eth0']
eth0.mtu = 5000
eth0.change()
you can do:
with links['eth0'] as eth0:
eth0.mtu = 5000

No real logick change

Nothing algorithmic changed really, just cosmetics
|
|
Now, python files use pseudo-tab equal 4 spaces
|
|
1. unused "import struct" removed
2. AddressFamily.__len__ is defined, but why in so way? removed.
3. comparison against instancemethod type fixed
|
|
1. Address, Link and Vlan classes affected with same bug
2. Flags property are not designed as set class. Setting to property will
not replace flags, just add flags to set. So, jist document that, and
fixed obvious logick.
