This patch introduces support for LXC specific public APIs. In
common with what was done for QEMU, this creates a libvirt_lxc.so
library and libvirt/libvirt-lxc.h header file.
The actual APIs are
int virDomainLxcOpenNamespace(virDomainPtr domain,
int **fdlist,
unsigned int flags);
int virDomainLxcEnterNamespace(virDomainPtr domain,
unsigned int nfdlist,
int *fdlist,
unsigned int *noldfdlist,
int **oldfdlist,
unsigned int flags);
which provide a way to use the setns() system call to move the
calling process into the container's namespace. It is not
practical to write in a generically applicable manner. The
nearest that we could get to such an API would be an API which
allows to pass a command + argv to be executed inside a
container. Even if we had such a generic API, this LXC specific
API is still useful, because it allows the caller to maintain
the current process context, in particular any I/O streams they
have open.
NB the virDomainLxcEnterNamespace() API is special in that it
runs client side, so does not involve the internal driver API.

libvirt Python Bindings README
==============================
Most of the libvirt python binding code is automatically generated
using the script generator.py, and the API description from
docs/libvirt-api.xml
Manually written files:
- libvirt-override.c: methods where the C binding needs to be hand crafted
- libvirt-override.py: global methods where the C and python bindings have different args
- libvirt-override-api.xml: methods where the auto-extracted API docs are not
suitable for python auto-generator. Overriding this if the method is going
into libvirt-override.c, but we still want auto-generated libvirt-override.py
- libvirt-override-virConnect.py: virConnect class methods
- typewrappers.h,.c: Python object wrappers for each libvirt C object
Auto-generated files:
- libvirt.py: The main python binding. Comprises auto-generated code, along
with contents from libvirt-override.py and libvirt-override-virConnect.py
- libvirt.c, libvirt.h: The C glue layer for the python binding. Comprises
auto-generated code, along with libvirt-override.c
- libvirt-export.c: List of auto-generated C methods, included into
the libvirt-override.c method table
