There is different spacing when listing active vs. inactive networks. Ex:

Name                 State      Autostart
-----------------------------------------
default              active     yes
xxxxxx               inactive no

Let the underlying driver tell us what it supports. At the moment
we are at least erroneously denying floppy eject/insert.

vol-clone is a convenience function, requiring only a volume to clone and a
new name.

vol-create-from is a direct mapping to the public API, which allows cloning
across pools, converting between formats, etc, but requires an xml file to be
passed

* src/virsh.c: fix missing authentication when command are issued
  from the shell, patch by Matthias Bolte
Daniel

* src/virsh.c (cmdNetworkList): Change format not to right-pad
with spaces, as that would have required a trailing blank in
an expected output file.

  patch by Mark McLoughlin.

Fix getpwuid_r() usage
Fix virsh migrateuri handling

* src/virsh.c: Use `""', not `gettext_noop("")', in numerous
vshCmdInfo definitions.  The latter provokes a warning from gettext.

This is the second part of the change mentioned here:

  http://thread.gmane.org/gmane.comp.emulators.libvirt/10331

It removes the essentially redundant "optname" parameter
from each of the vshCommandOptNetworkBy and vshCommandOptDomainBy
functions as well as the correspond macros (without "By" suffix).
Now, instead of always passing the optname, "domain", to
vshCommandOptDomainBy, that function requires that its command
argument refer to an opts array containing a "domain" option.

This normalization makes one more help-related change:
it renames the net-start "name" argument to the more
sensible and consistent "network".
* src/virsh.c (VSH_BYNAME, vshCommandOptDomain)
(cmd_has_option): New function, used in vshCommandOptDomainBy
and vshCommandOptNetworkBy.
(vshCommandOptDomainBy, vshCommandOptNetworkBy): Remove the optname
parameter, it's always "domain" ("network").  Update all callers.
Call cmd_has_option.

* src/Makefile.am (virsh-pool-edit.c): This code is generated
from cmdEdit, and cmdEdit uses the vshCommandOptDomain macro which
now, with the changes above, has only 3 (was 4) arguments, yet the
macro use is mapped to vshCommandOptPool, which still requires 4
arguments.  So this change adjusts the sed code to reinsert the
just-removed argument -- we're not changing pool-related code right
now, because it's not as straight-forward.

* qemud/remote_generate_stubs.pl: Likewise.

* tests/testutils.h: Likewise.

* src/virsh.c (cmdPoolStart, cmdStart): Change hard-coded
vshCommandOptDomainBy string argument to match just-changed
option name.  Cole Robinson reported that "virsh start" was
broken and provided that part of the fix.
Bug introduced by yesterday's "virsh.c: tweak options to produce
more accurate help".
* tests/start: New file.  Test for the above fix.
* tests/Makefile.am (test_scripts): Add start.

* src/virsh.c: Adjust some vshCmdOptDef command option flags
to improve auto-generated help command syntax.

* src/virsh.c: ... now that info is generated.

* src/virsh.c: Now, every command must have a "desc" string,
even if it has zero length.  Mark these, so they'll be filled in.

* src/virsh.c: Also, diagnose extra arguments after --help (-h).

* tests/virsh-synopsis: new file
* tests/Makefile.am (test_scripts): Add virsh-synopsis.
* src/virsh.c: Correct help SYNOPSIS for each of seven commands.

When I first ran this script, "make check" failed like this:
  ...
  invalid help SYNOPSIS for net-create:
      create a network from an XML <file>
  invalid help SYNOPSIS for net-define:
      define a network from an XML <file>

Building with --disable-nls exposed many new warnings like these:
virsh.c:4952: warning: format not a string literal and no format ...
util.c:163: warning: format not a string literal and no format arguments
All but one of the following changes add a "%s" argument before
the offending _(...) argument.

This was the only manual change:
* src/lxc_driver.c (lxcVersion): Use %s and strerror(errno)
rather than %m, to avoid a warning from gcc -Wformat-security.

Add "%s" before each warned about format-string-with-no-%-directive:
