Any time we have a string with no % passed through gettext, a
translator can inject a % to cause a stack overread.  When there
is nothing to format, it's easier to ask for a string that cannot
be used as a formatter, by using a trivial "%s" format instead.

In the past, we have used --disable-nls to catch some of the
offenders, but that doesn't get run very often, and many more
uses have crept in.  Syntax check to the rescue!

The syntax check can catch uses such as
virReportError(code,
               _("split "
                 "string"));
by using a sed script to fold context lines into one pattern
space before checking for a string without %.

This patch is just mechanical insertion of %s; there are probably
several messages touched by this patch where we would be better
off giving the user more information than a fixed string.

Update the storage driver to use virReportError instead of

Storage is one of the last domains in libvirt where we don't fully
utilize inactive and live XML. Okay, it might be because we don't
have support for that. So implement such support. However, we need
to fallback when talking to old daemon which doesn't support this
new flag called VIR_STORAGE_XML_INACTIVE.

Currently, we share the idea of old & new def with domains. Users can
*-edit an object (domain, pool) which spawns a new internal
representation for them. This is referenced via
{domainObj,poolObj}->newDef [compared to ->def]. However, for pool we
were never overwriting def with newDef. This must be done on
pool-destroy (like we do analogically in domain detroy).

Remove the uid param from virGetUserConfigDirectory,

This offers a number of advantages:
 * Allows sharing a home directory between different machines, or
sessions (eg. using NFS)
 * Cleanly separates cache, runtime (eg. sockets), or app data from
user settings
 * Supports performing smart or selective migration of settings
between different OS versions
 * Supports reseting settings without breaking things
 * Makes it possible to clear cache data to make room when the disk
is filling up
 * Allows us to write a robust and efficient backup solution
 * Allows an admin flexibility to change where data and settings are stored
 * Dramatically reduces the complexity and incoherence of the
system for administrators

Lets say I got a volume with '1G' allocation and '10G' capacity. The
available space in the parent pool is '5G'. With the current check for
overcapacity, I can only try to resize to <= '6G'. You see the problem?

Currently, if scrub (used for wiping algorithms) is not present
at compile time, we don't support any other wiping algorithms than
zeroing, even if it was installed later. Switch to runtime detection
instead.

Currently only VIR_STORAGE_VOL_RESIZE_DELTA flag is supported.

Currently, we support only filling a volume with zeroes on wiping.
However, it is not enough as data might still be readable by
experienced and equipped attacker. Many technical papers have been
written, therefore we should support other wiping algorithms.

* src/storage/storage_driver.c: As virStorageVolLookupByPath lookups
all the pool objs of the drivers, breaking when failing on getting
the stable path of the pool will just breaks the whole lookup process,
it can cause the API fails even if the vol exists indeed. It won't get
any benefit. This patch is to fix it.

Fix bug #611823 storage driver should prohibit pools with duplicate
underlying storage.

Add internal API virStoragePoolSourceFindDuplicate() to do uniqueness
check based on source location infomation for pool type.

Although we are flushing cache after some critical writes (e.g.
volume creation), after some others we do not (e.g. volume cloning).
This patch fix this issue. That is for volume cloning, writing
header of logical volume, and storage wipe.

Revert 6a1f5f56.  Now that libvirt_iohelper takes fds by
inheritance rather than by open() (commit 1eb66479), there is
no longer a race where the parent can unlink() a file prior to
the iohelper open()ing the same file.  From there, it makes
more sense to have the callers both create and unlink, rather
than the caller create and the stream unlink, since the latter
was only needed when iohelper had to do the unlink.

Many operations are not valid on inactive storage pools. The

VIR_ERR_OPERATION_INVALID

  is not active

When libvirt starts up all storage pools default to the inactive
state, even if the underlying storage is already active on the
