4362ff4337 virsh: use vshError consistently after virBufferError checks
If virBufferError() reports an error, then vshError() is needed to
report the error situation instead of a simple vshError().

a144f28467 virsh: avoid i18n puzzle
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.

b620bdee14 virsh: respect -q/--quiet more
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.

18701e9d62 virsh: Fix core for cmdSecretGetValue
https://bugzilla.redhat.com/show_bug.cgi?id=1366611

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.

4914494eb8 virt-admin: Fix the error when an invalid URI has been provided
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.

2197ea56d7 conf: Add IOThread quota and period scheduler/cputune defs
https://bugzilla.redhat.com/show_bug.cgi?id=1356937

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 only function that we currently use from glib is g_sprintf().
That's a very big gun for such small target. Not only that, but

f5f32bcd1b admin: Fix default uri config option name s/admin_uri_default/uri_default
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.

d02ef33451 tools: Make use of the correct environment variables
Since commit 834c5720 which extracted the generic functionality out of virsh
and made it available for other clients like virt-admin to make use of it, it
also introduced a bug when it renamed the original VIRSH_ environment variables
to VSH_ variables. Virt-admin of course suffers from the same bug, so this
patch modifies the generic module vsh.c to construct the correct name for
environment variables of each client from information it has.

0ef07e19c7 vsh: Make vshInitDebug return int instead of void
Well, the reason behind this change is that if the function is extended in some
way that e.g. would involve allocation we do not have a way of telling it to
the caller. More specifically, vshInitDebug only relies on some hardcoded
environment variables (by a mistake) that aren't documented anywhere so neither
virsh's nor virt-admin's documented environment variables take effect. One
possible solution would be duplicate the code for each CLI client or leave the
method be generic and provide means that it could figure out, which client
called it, thus initializing the proper environment variables but that could
involve operations that might as well fail in certain circumstances and the
caller should know that an error occurred.

bd93ba64fd vsh: Properly initialize res
The 'res' variable was only being initialized to NULL in the

res is assigned one of two results based on a pair of if then else if
conditions. If for some reason neither of those paths was taken and
the (!state) path wasn't taken, then 'res' would be indeterminate.
