This patch adds a helper function with similar semantics to
vshCommandOptString that requests a string argument, but does some error
reporting without the need to do it in the functions themselves.
The error reporting also provides information about the parameter whose
retrieval failed.
Way back when I started making changes for Coverity messages my first set
were to a bunch of CHECKED_RETURN errors. In particular virAsprintf() had
a few callers that Coverity noted didn't check their return (although some
did check if the buffer being printed to was NULL or not).
It was suggested at the time as a further patch an ATTRIBUTE_RETURN_CHECK
should be added to virAsprintf(), see:
https://www.redhat.com/archives/libvir-list/2013-January/msg00120.html
This patch does that and fixes a few more instances not found by Coverity
that failed the check.
When a disk-only snapshot is requested the domain is treated as if it
was offline. This forbids to mix memory checkpoints with the DISK_ONLY
flag.
This patch improves the error message and mentions the restriction in
the virsh man page.
Linefeed is missed in the help of node-memory-tune.
This patch just adds '\n' to get a correct help message.

This patch fixes the following issues in the cpu-stats virsh command:
1) Renames label failed_params to no_memory to match coding style
2) Uses proper typed parameter cleanup in error paths to avoid leaks
3) Adds a ret variable and simplifies error labels
4) Changes error message to a slightly more descriptive one and gets rid
of the newline at the end:
Before:
$ virsh cpu-stats tr
error: Failed to virDomainGetCPUStats()
error: Requested operation is not valid: domain is not running
After:
$ tools/virsh cpu-stats tr
error: Failed to retrieve CPU statistics for domain 'tr'
error: Requested operation is not valid: domain is not running
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

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
