Change the logic in a way, so that VSH_CMD_FLAG_ALIAS behaves similarly to
how VSH_OT_ALIAS for command options, i.e. there is no need for code duplication
for the alias and the aliased command structures. Along with that change,
switch any existing VSH_CMD_FLAG_ALIAS occurrences to this new format. Also,
since this patch introduces a new command structure element, adjust the
virsh-self-test test to make sure we won't ever miss to specify the '.alias'
member for an aliased command because doing that would lead to an internal
error.

Recent changes extracted the command internals validation routine from
vshCmddefOptParse method which now just calls vshCmddefOptFill. Therefore, make
vshCmddefOptFill the new vshCmddefOptParse and drop the unnecessary name.

Originally introduced by commit 2432521e which correctly split
vshCmddefOptParse into command's options validation and options parsing.
However, command's 'internals' are not tied solely to .options, rather it
should be about the overall structure, therefore the validation should be
extracted from vshCmddefOptParse and performed only within our test suite, i.e.
in vshSelfTest.

If the initial check is true the function immediately returns so there's no
need to enclose the code following the check within an 'else' block.
Also, by removing the 'else' block, the declarations need to be moved to
beginning of the function block to conform with our guidelines.

The intention is to move vshCmddefCheckInternals out of vshCmddefOptParse to
our test suite. First step to do that is to enforce checking for an existing
help string (that also means it's non-empty) in a command because a command
without a help is not much of a use.

virsh maxvcpus --type kvm output is useless on PPC. Also, in
commit e6806d79 we documented not rely on virConnectGetMaxVcpus
output. Fix the maxvcpus to use virConnectGetDomainCapabilities
now to make it useful. The call is made to use the default emulator
binary and to check for the host machine and arch which is what the
command intends to show anyway.

When using
virsh net-event non-existing-net
the error message says that 'either --list or event type is required'
This is misleading as 'virsh net-event $valid-event-type' is not going
to work either. What is expected is 'virsh net-event --event
$valid-event-type'
This commit fixes the string in pool-event, nodedev-event, event, and
net-event.
This patch is to delete the extra wrap "\n" after failed vol-resize
error for both "Failed to change size of volume to" and "Failed to change
size of volume by". For error with wrap, there will be an extra wrap
between two errors, such as:
(1)# virsh vol-resize --pool default --vol vol-test 5M
error: Failed to change size of volume 'vol-test' to 5M
error: invalid argument: Can't shrink capacity below current capacity unless shrink flag explicitly specified
(2)# virsh vol-resize /var/lib/libvirt/images/volds --shrink --delta 10M
error: Failed to change size of volume 'volds' by 10M
error: invalid argument: can't shrink capacity below existing allocation
Unfortunately, commit a8962f70 only fixed first half of the reported issue of
virt-admin outputting negative values where unsigned int is expected by
BZ below, so this commit represents the other missing half of the fix.

This patch changes the signature of vshCompleters, allowing to pass along

we might want to pass the autocomplete vshControl along with the

Having After=libvirtd.service merely ensures that, if both
services are asked to start, libvirtd.service will start
first.
What we really want is for libvirtd.service to be started
whenever libvirt-guests.service is asked to start. Adding a
Requires= relationship guarantees that will happen.
We use a separate line for each After= relationship in other
unit files: do the same here for consistency's sake, and also
to make future changes nicer to diff
libvirt-guests.service does both suspend *and* resume guests,
depending on whether it's being started or stopped: the
description should reflect this, to avoid confusing messages
during startup.
Replace "active" with "running" (to match virsh list's output)
and don't capitalize libvirt.
Call option completers if argument completion is requested using the
corresponding option completer, if it is defined.

When we wanted to break huge and unmaintainable virsh into
smaller files first thing we did was to just move funcs into
virsh-.c files and then #include them from virsh. Having it done
this way we also needed to have them listed under EXTRA_DIST.
However, things got changed since then and now all the virsh-*.c
files are proper source files. Therefore they are listed under
virsh_SOURCES too. But for some reason we forgot to remove them
from EXTRA_DIST.

virVcpuInfo contains the vcpu number that the data refers to. Report
what's returned by the daemon rather than the sequence number as with
sparse vcpu topologies they won't match.
Use the full versions of the message, instead of composing a base
message with what was updated; the change makes the messages properly
translatable, since different parts of a sentence might need different
declensions for example.
Turn various vshPrint() informative messages into vshPrintExtra(), so
they are not printed when requesting the quiet mode; neither XML/info
outputs nor the results of commands are affected.
Also change the expected outputs of the virsh-undefine test, since virsh
is invoked in quiet mode there.
Some informative messages might still be converted (and thus silenced
when in quiet mode), but this is an improvements nonetheless.

When commit id 'cb2e3e50' reworked the cmdSecretGetValue call to use
VIR_DISPOSE_STRING for base64, it neglected to initialize the base64
value to NULL since the cleanup: label could be reached prior to the
base64 value being set or not. This resulted in a core dump, adding
the initialization will avoid the issue.
After commit 9d479dd1 fiddled with the cmdConnect's output which used to be a
bit more verbose prior to the mentioned commit, the program flow would result
in a quite confusing error if an invalid URI has been provided:
error: Failed to connect to the admin server
Connected to the admin server
error: <some error>
The problem is that the commit mentioned above relied on the fact that
connect routine always succeeds which is not true.

Add the definitions to allow for viewing/setting cgroup period and quota
limits for IOThreads.
This is similar to the work done for emulator quota and period by
commit ids 'b65dafa' and 'e051c482'.
Being able to view/set the IOThread specific values is related to more
recent changes adding global period (commmit id '4d92d58f') and global
quota (commit id '55ecdae') definitions and qemu support (commit id
'4e17ff79' and 'fbcbd1b2'). With a global setting though, if somehow
the IOThread value in the cgroup hierarchy was set "outside of libvirt"
to a value that is incompatible with the global value.
Allowing control over IOThread specific values provides the capability
to alter the IOThread values as necessary.
The prettified JSON string already contains a newline so don't print
another one. This allows to pipe the json output (in conjunction with
the --quiet option) to files without having to truncate them afterwards.

The original name 'admin_uri_default' was introduced to our code by commit
dbecb87f. However, at that time we already had a separate config file for
admin library but the commit mentioned above didn't properly adjust the
config's option name. The result is that when we're loading the config, we
check a non-existent config option (there's not much to do with the URIs
anyway, since we only allow local connection). Additionally, virt-admin's man
page documents, that the default URI can be altered by setting
admin_uri_default option. So the fix proposed by this patch leaves the
libvirt-admin.conf as is and adjusts the naming in the code as well as in the
virt-admin's man page.
