To allow to use libsss_nss_idmap from python applications, e.g. the
FreeIPA server, the patch adds pythin bindings to libsss_nss_idmap. The
contributed spec file will place the python bindings in a new package
called libsss_nss_idmap-python.

Alexander Bokovoy <abokovoy@redhat.com> kindly provided the code to
check the type of the python objects and loop over the list entries.

This patch add a library for client side lookups for a SID or with a
SID through the calls:
- sss_nss_getsidbyname
- sss_nss_getsidbyid
- sss_nss_getnamebysid
- sss_nss_getidbysid
The library is called libsss_nss_idmap and the contributed spec file
will create two new packages libsss_nss_idmap and
libsss_nss_idmap-devel.

Package sssd contains python files. Python files should be installed
in noarch package, therefore all python files from directory
src/config/SSSDConfig was moved to new noarch package python-sssdconfig.

Update the monitor code to be using the new libnl3 API.

Changed configure option
--with-libnl

By default, it tries to build with libnl3, if not found, then with
libnl1, if this isn't found either, build proceeds without libnl, just
with warning.

Specifing --with-libnl=<libnl3|libnl1|no> checks for the specific given
version, if not found, configure ends with error.

Some of the tests (such as the sysdb tests) are highly I/O limited.
By running them on a ramdisk, we can significantly speed up the
test runs when doing a distcheck or RPM build.

There is a large amount of duplicated code being linked into multiple
SSSD binaries. Instead of statically linking this code throughout the
SSSD, we should instead create private shared libraries for them and
drop this code on the system only once.
