fix this problem by checking if selinuxfs is mounted
in host before we try to create dir /sys/fs/selinux.

Commit 509eb51e added lxc_protocol.x; but without the initial
checkin of src/lxc_protocol-structs, 'make check' would fail for
anyone with pdwtags installed:
make[3]: *** No rule to make target `lxc_protocol-structs', needed by `check-protocol'.  Stop.

* src/lxc_protocol-structs: New file.

The virDomainLxcOpenNamespace method needs to open every file
in /proc/$INITPID/ns and return the open file descriptor to the
client application.

Make cpuset local to the while loop and free it once done with it each
time through the loop.  Add a sa_assert() to virBitmapParse() to keep Coverity
from believing there could be a negative return and possible resource leak.

Added some messaging to indicate possible failure from virXPathULongLong()
as well

Commit-id 'afc4631b' added the regfree(reg) to free resources alloc'd
during regcomp; however, reg still needed to be VIR_FREE()'d. The call
to regfree() also didn't account for possible NULL value.  Reformatted
the call to be closer to usage.

Commit c308a9ae was incomplete; it resolved the configure failure,
but not a later build failure.

* src/util/virnetdevbridge.c: Include pre-req header.
* configure.ac (AC_CHECK_HEADERS): Prefer standard in.h over
non-standard ip6.h.

Some places missed the conversion from LIBCURL_{CFLAGS,LIBS} to
CURL_{CFLAGS,LIBS}, and a part of curl check was left in
configure.ac instead of m4/virt-curl.m4 by mistake

Mark virDomainLxcEnterNamespace as skipped in python binding
and remove reference to lxcDomainOpenNamespace which doesn't
arrive until a later patch

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.

This converts the libssh2 configure check to use LIBVIRT_CHECK_PKG.
Previously it would check version 1.0 and 1.3, but this simplifies
things to just require version 1.3

Commit 321a7d53 missed a spot.

* src/rpc/virnetsocket.c (virNetSocketPreExecRestart): Use right
conditional.

Commit f8d478b6 broke the grouping by
five items.

If addition of rules in networkAddIptablesRules() failed the real error
was masked by error reported when trying to clean up the remaining
rules.

With this patch the original error message is saved and set back after
the removal is complete.

Commit 0211fd6e introduced regression
where newly defined networks were not made persistent.

This patch makes the network persistent on each successful definition.
