Generation of the ACL API policy is a "automated process"
based on this perl script which "worked" with the changes to
add nwfilter binding API's because they had the "nwfilter"
prefix; however, the generated output name was incorrect
based on the remote protocol algorithm which expected to
generate names such as 'nwfilter-binding.action' instead
of 'nwfilter.binding-action'.

This effectively changes src/access/org.libvirt.api.policy entries:

  org.libvirt.api.nwfilter.binding-create ==>
      org.libvirt.api.nwfilter-binding.create

  org.libvirt.api.nwfilter.binding-delete ==>
      org.libvirt.api.nwfilter-binding.delete

  org.libvirt.api.nwfilter.binding-getattr ==>
      org.libvirt.api.nwfilter-binding.getattr

  org.libvirt.api.nwfilter.binding-read ==>
      org.libvirt.api.nwfilter-binding.read

For now, there are 9 test cases
- testVshTableNew: Creating table with empty header
- testVshTableHeader: Printing table with/without header
- testVshTableRowAppend: Appending row with various number of cells.
  Only row with same number of cells as in header is accepted.
- testUnicode: Printing table with unicode characters.
  Checking correct alignment.
- testUnicodeArabic: test opposite (right to left) writing
- testUnicodeZeroWidthChar
- testUnicodeCombiningChar
- testUnicodeNonPrintableChar,
- testNTables: Create and print varios types of tables - one column,
  one row table, table without content, standart table...

Instead of printing it straight in virsh, it creates table struct
which is filled with header and rows(domains). It allows us to know
more about table before printing to calculate alignment right.
Signed-off-by: NSimon Kobyda <skobyda@redhat.com>

It solves problems with alignment of columns. Width of each column
is calculated by its biggest cell. Should solve unicode bug.
In future, it may be implemented in virsh, virt-admin...

This API has 5 public functions:
- vshTableNew - adds new table and defines its header
- vshTableRowAppend - appends new row (for same number of columns as in
header)
- vshTablePrintToStdout
- vshTablePrintToString
- vshTableFree

With the current implementation, adding a new architecture

We should compare the alias/qdev id only when it was provided by the
caller and when it was found in the reply. Otherwise we could
dereference a NULL pointer. STRNEQ_NULLABLE is not appropriate since
it would return 'true' if the string was not present in the JSON output.

In cases where virProcessKillPainfully already reailizes that
SIGTERM wasn't enough we are partially on a bad path already.
Maybe the system is overloaded or having serious trouble to free and
reap resources in time.

In those case give the SIGKILL that was sent after 10 seconds some more
time to take effect if force was set (only then we are falling back to
SIGKILL anyway).

It was found that in cases with host devices virProcessKillPainfully
might be able to send signal zero to the target PID for quite a while
with the process already being gone from /proc/<PID>.

That is due to cleanup and reset of devices which might include a
secondary bus reset that on top of the actions taken has a 1s delay
to let the bus settle. Due to that guests with plenty of Host devices
could easily exceed the default timeouts.

To solve that, this adds an extra delay of 2s per hostdev that is associated
to a VM.
