This was originally used to propagate the bridge and veth names across
hosts, but now we extract both from the container's config file, and
nothing reads the files that dump_net_info() writes, so let's just get rid
of them.

When setting lxc.network.veth.pair to get a fixed interface
name the recreation of it after a reboot caused an EEXIST.
-) The reboot flag is now a three-state value. It's set to
1 to request a reboot, and 2 during a reboot until after
lxc_spawn where it is reset to 0.
-) If the reboot is set (!= 0) within instantiate_veth and
a fixed name is used, the interface is now deleted before
being recreated.

templates: lxc-opensuse, use rpm to determine build version

Fix error message when cannot find an lxc-init

zypper info's output is not usable for several reasons:
* it is localized -- there is no "Version: " in my output
* it shows results both from the repo and local system

So use plain rpm to determine whether build is installed and if proper
version is in place.

Update for commit 1940bff4Signed-off-by: Sungbae Yoo <sungbae.yoo@samsung.com>

This commit adds an -R, --rename option to lxc-clone to rename a container. As
c->rename calls do_lxcapi_rename() which in turn calls do_lxcapi_clone() it
seemed best to implement it in lxc-clone rather than lxc-snapshot which also
calls do_lxcapi_clone(). Some additional unification regarding the usage of
return vs exit() in main() was done.

seccomp: simplify and fix rule parsing

1) Two checks on amd64 for whether compat_ctx has already
been generated were redundant, as compat_ctx is generally
generated before entering the parsing loop.

2) With introduction of reject_force_umount the check for
whether the syscall has the same id on both native and
compat archs results in false behavior as this is an
internal keyword and thus produces a -1 on
seccomp_syscall_resolve_name_arch().
The result was that it was added to the native architecture
twice and never to the 32 bit architecture, causing it to
have no effect on 32 bit containers on 64 bit hosts.

3) I do not see a reason to care about whether the syscalls
have the same number on the two architectures. On the one
hand this check was there to avoid adding it to two archs
(and effectively leaving one arch unprotected), while on
the other hand it seemed to be okay to add it to the
same arch *twice*.

The entire architecture checking branches are now reduced to
three simple cases: 'native', 'non-native' and 'all'. With
'all' adding to both architectures regardless of the syscall
ID.

Also note that libseccomp had a bug in its architecture
checking, so architecture related filters weren't working as
expected before version 2.2.2, which may have contributed to
the confusion in the original architecture-related code.

A user could otherwise over-mount /proc and prevent the apparmor profile
or selinux label from being written which combined with a modified
