This reverts commit 4e7ccf8713.

I mistakenly pushed it along with the Admin API series.

4e7ccf8713 Example virt-admin
You had only one job.  That's what you can say about this example
binary.  In future, parts of virsh that are usable for this binary
should be split into separate shell-utils and virt-admin should gain all
the cool features of virsh without too much code addition.

a02a161bb8 qemu: libxl: vcpupin: Don't reset pinning when pinning to all pcpus
In the pre-NUMA ages pinning a vCPU to all pCPUs was eaqual to deleting
the pinning info. Now it does not entirely work that way. Pinning a vCPU
to all pCPUs might be a desired operation. Additionally removal of the
pinning will result into using the default pinning information at the
next boot which might be different from all vcpus.

This patch removes the false assumption that we should remove the
pinning after pinning to all vCPUs and tweaks the documentation for
virsh.

A later patch will implement a new flag for the virDomainPinVcpuFlags
API that will allow to remove the pinning in a sane way.

e9507fd41c virsh: Fix Ctrl-C behavior when watching a job
When watching a job (save, managedsave, dump, migrate) virsh spawns a
thread to call the appropriate API and waits for the result while
watching for interruption signals (SIGINT, Ctrl-C on the terminal).
Whenever such signal is caught, virsh calls virDomainAbortJob, stops
waiting for the job, and returns the result of virDomainAbortJob.

This is wrong because the job might have finished in the meantime or it
might have been cancelled by someone else and virsh would just report
the failure to abort the job. However, we are not interested in the
virDomainAbortJob's result at all, we need to keep waiting for the main
job to finish and report its result instead.

be6ff4da95 virsh: Pass vshControl to all vshCommandOpt*() calls
This will allow us to use vshError() to report errors from inside
vshCommandOpt*(), instead of replicating the same logic and error
messages all over the place.

We also have more context inside the vshCommandOpt*() functions,
for example the actual value used on the command line, which means
we can produce more detailed error messages.

vshCommandOptBool() is the exception here, because it's explicitly
designed not to report any error.

0a33bba1ae virsh: make negative values with vol-resize more convenient
When shrinking a volume by a certain size, instead of typing
  vol-resize volume 1G --delta --shrink
we allow the convience of specifying a negative value:
  vol-resize volume -1G --delta --shrink
getting the same results with one more character.

A negative value only makes sense as a delta. Imply the
--delta parameter if the value is negative.

Still require --shrink, because the operation is potentially
destructive.

aa9f139599 migration: Usable time statistics without requiring NTP
virDomainGetJobStats is able to report statistics of a completed
migration, however to get usable downtime and total time statistics both
hosts have to keep synchronized time. To provide at least some
estimation of the times even when NTP daemons are not running on both
hosts we can just ignore the time needed to transfer a migration cookie
to the destination host. The result will be also inaccurate but a bit
more predictable. The total/down time will just be at least what we
report.

31ef0836a7 virsh: fix regression in 'virsh event' by domain
Commit a0670ae caused a regression in 'virsh event' and
'virsh qemu-monitor-event' - if a user tries to filter the
command to a specific domain, an error message is printed:

$ virsh event dom --loop
error: internal error: virsh qemu-monitor-event: no domain VSH_OT_DATA option

and then the command continues as though no domain had been
supplied (giving events for ALL domains, instead of the
requested one).  This is because the code was incorrectly
assuming that all "domain" options would be supplied via a
mandatory VSH_OT_DATA, even though "domain" is optional for
these two commands, so we had changed them to VSH_OT_STRING
to quit failing for other reasons (ever since it was decided
that VSH_OT_DATA and VSH_OT_STRING should no longer be
synonyms).

In looking at the situation, though, the code for looking up
a domain was making a pointless check for whether the option
exists prior to finding the option's string value, as
vshCommandOptStringReq does just fine at reporting any errors
when looking up a string whether or not the option was present.

So this is a case of regression fixing by pure code deletion :)

0e7457e501 Fix common misspellings
Wikipedia's list of common misspellings [1] has a machine-readable
version.  This patch fixes those misspellings mentioned in the list
which don't have multiple right variants (as e.g. "accension", which can
be both "accession" and "ascension"), such misspellings are left
untouched.  The list of changes was manually re-checked for false
positives.
