All callers of virStorageFileGetMetadataFromBuf were first calling
virStorageFileProbeFormatFromBuf, to learn what format to pass in.
But this function is already wired to do the exact same probe if
the incoming format is VIR_STORAGE_FILE_AUTO, so it's simpler to
just refactor the probing into the central function.

strtoul() is required to parse negative numbers as their
twos-complement positive counterpart.  But sometimes we want

also parses 0, but 'non-negative' doesn't lend itself to a

To avoid memory leak of the "backingStoreRaw" field when reparsing
backing chains a new function is being introduced by this patch that
shall be used to clear backing store information.

The memory leak was introduced in commit 8823272d.

SO_REUSEADDR on Windows is actually akin to SO_REUSEPORT
on Linux/BSD. ie it allows 2 apps to listen to the same
port at once. Thus we must not set it on Win32 platforms

Create a nwfilterxml2firewalltest to exercise the
ebiptables_driver.applyNewRules method with a variety of
different XML input files. The XML input files are taken

The network and nwfilter drivers both have a need to update
firewall rules. The currently share no code for interacting
with iptables / firewalld. The nwfilter driver is fairly
tied to the concept of creating shell scripts to execute
which makes it very hard to port to talk to firewalld via
DBus APIs.

This patch introduces a virFirewallPtr object which is able
to represent a complete sequence of rule changes, with the
ability to have multiple transactional checkpoints with
rollbacks. By formally separating the definition of the rules
to be applied from the mechanism used to apply them, it is
also possible to write a firewall engine that uses firewalld
DBus APIs natively instead of via the slow firewalld-cmd.

Each backing store of a given disk is associated with a unique index
(which is also formatted in domain XML) for easier addressing of any
particular backing store. With this patch, any backing store can be
addressed by its disk target and the index. For example, "vdc[4]"
addresses the backing store with index equal to 4 of the disk identified
by "vdc" target. Such shorthand can be used in any API in place for a
backing file path:

Remove the 'StorageBackend' from names of the functions and fix
indentation.

The only storage-specific parameter is the pool object, which
is only used for passing to the callback function.

A earlier commit changed the global log buffer so that it only
records messages that are explicitly requested via the log
filters setting. This removes the performance burden, and
improves the signal/noise ratio for messages in the global
buffer. At the same time though, it is somewhat pointless, since
all the recorded log messages are already going to be sent to an
explicit log output like syslog, stderr or the journal. The
global log buffer is thus just duplicating this data on stderr
upon crash.

The log_buffer_size config parameter is left in the augeas
lens to prevent breakage for users on upgrade. It is however
completely ignored hereafter.
