Rather than overloading one function - split apart the logic to have
separate interfaces and local/private structures to manage the data
for which the helper is collecting.

Rather than 'nuuids' it should be 'maxuuids' and rather than 'got'
it should be 'nuuids'. Alter the logic of the list traversal to
utilize those names.

Rather than using "ret = -1" and cleanup processing, alter the return
path on failure to goto error and then just return the data.got.
In the error path, we no longer check for ret < 0, we just can free
anything added to the array and return -1 directly.

When processing a virSecretPtr use 'secret' as a variable name.
When processing a virSecretObjPtr use 'obj' as a variable name.
When processing a virSecretDefPtr use 'def' as a variable name,
unless a distinction needs to be made with a 'newdef' such as
virSecretObjListAddLocked (which also used the VIR_STEAL_PTR macro
for the configFile and base64File).

Only save the config when using a generated UUID if we were able to
create an object for the def. There could have been "other reasons"
for the assignment to fail, so saving the config could be incorrect.

Future adjustments will be privatizing the object more, so this just

Instead of figuring out upfront whether <input> will be a single
or a pair element, format the subelements into a separate buffer
and close <input/> early if this buffer is empty.
There's lot more to document about the nodedev driver, besides PCI and
SR-IOV (even this might need to be extended), but let's start small-ish
and at least have a page for it linked from the drivers.html.

During 'matrix' testing of all possible combinations I found that if
device is formated with "gpt" first, then an attempt is made to format
using "mac", a startup will fail.
Deeper analysis by Peter Krempa indicates that the "mac" table fits
into the first block on the disk. Since the GPT disklabel is stored
at LBA address 1 it is not overwritten at all. Thus it's apparent that
the (blkid) detection tool then prefers GPT over a older disklabel.
The GPT disklabel has also a secondary copy at the last LBA of the disk.
So, follow the same logic as the logical pool in clearing a 1MB swath
at the beginning and end of the device to avoid potential issues with
larger sector sizes for the device.
Also fixed a minor formatting nit in virStorageBackendDeviceIsEmpty call.
Create a wrapper/helper that can be used to call the storage backend
wipe helper - storageBackendVolWipeLocalFile for future use by logical
and disk backends to clear out the partition table rather than having
each open code the same algorithm.
Add bool 'zero_end' and logic that would allow a caller to wipe specific
portions of a target device either from the beginning (the default) or
from the end when zero_end is true.
This will allow for this code to wipe out partition table information
from a device.
There were a few bugs in keycodemap tool that broke it

A long time ago we imported the keymaps.csv file from GTK-VNC so we
can do conversions between keycode sets. Meanwhile lots of bug fixes
have gone into this CSV file and libvirt hasn't kept in sync. The
keymaps.csv file and associated generator script has been pulled out
of GTK-VNC into a dedicated GIT repo for use as a submodule. This
allows GTK-VNC, SPICE-GTK, QEMU and libvirt to share the same master
database and tools and pushing updates merely requires a submodule
commit update as with gnulib.
The test suite is updated to cover some extra boundary conditions.

Shorten the time needed to keep the list lock and alter the cleanup
path to be more of an error path.
Utilize the the virObjectListFree function to handle the calls for
virObjectUnref on each list element and the VIR_FREE of the list
instead of open coding it.
Change the name of the virHashForEach callback to match the name
of the Export function with the Callback added onto it.

Since we're assigning the 'client' to our callback event lookaside list,
it's imperative that we grab a reference to the object; otherwise, when
the object is unref'd during virNetServerProcessClients when it's determined
that the virNetServerClientIsClosed and the memory is free'd before perhaps
the object event state callbacks are run. When a virObjectLock() is run,
before sending the message the following trace occurs;

The goal is twofold: firstly, we want to extend the script so
that it can deal with more than a single git submodule, and
secondly we'd like to reduce the amount of duplicated code.
Moreover, since we're making heavy changes to the code anyway,
we might as well make sure it follows a somewhat consistent
coding style too.
To reduce code duplication, we introduce a new --dry-run
option, which can be used by third parties to figure out
whether calling autogen.sh is necessary or not: this allows
us to get rid of the reimplementation of part of the logic
in cfg.mk and guarantee they'll never get out of sync.
Other changes include: making dirty submodules checking and
cleaning entirely independent of other operations; removing
the use of 'set -e' and handling errors explicitly instead;
better parsing of command line arguments.
Currently, virNetDevSetCoalesce() stub is always returning error. As
it's used by virNetDevTapCreateInBridgePort(), it essentially breaks
bridged networking if coalesce is not supported.
To make it work, relax the stub to trigger error only when its
coalesce argument is not NULL, otherwise report success.
Since we do have this template at hand, why not using it wherever
possible (list of supported pool types and remote access section).
Also, perform some stylistic micro adjustments.
