It was possible to call VIR_FREE in error prior to initialization.

The function is just a renamed public version of former
virTypedParameterArrayClear.

Add a 'lxc-enter-namespace' command which accepts a domain name
and then a command + args to run, attached to the container

eg

  virsh -c lxc:/// lxc-enter-namespace demo -- /bin/ps -auxf

* tools/virsh.pod: Fix typo.

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 patch changes whitespace and the length of the separation line from
this format:

$ virsh net-list --all
Name                 State      Autostart     Persistent
--------------------------------------------------
default              inactive   yes           yes

to

$ virsh net-list --all
 Name                 State      Autostart     Persistent
----------------------------------------------------------
 default              inactive   yes           yes

to match the output of virsh list.

The QEMU specific APIs all operate on domains, not the host,
so should be in the virsh-domain.c file / group

See also commit 66ff2ddc, where we avoided installing these files
as executables.

* daemon/Makefile.am (libvirtd.service): Drop chmod.
* tools/Makefile.am (libvirt-guests.service): Likewise.
* src/Makefile.am (virtlockd.service, virtlockd.socket):
Likewise.

We had several different styles of .in conversion in our Makefiles:
ALLCAPS, @ALLCAPS@, @lower@, ::lower::
Canonicalize on one form, to make it easier to copy and paste
between .in files.

Also, we were using some non-portable sed constructs: \@ is an
undefined escape sequence (it happens to be @ itself in GNU sed,
but POSIX allows it to mean something else), as well as risky
behavior (failure to consistently quote things means a space
in $(sysconfdir) could throw things off; also, Autoconf recommends
using | rather than , or ! in the s||| operator, because | has to
be quoted in shell and is therefore less likely to appear in file
names than , or !).

Fix all of these uses to follow the same syntax.
