In an effort to remove the 'Long' variants of XPath number fetching

The aim of qemuDomainGetPreservedMounts() is to get a list of
filesystems mounted under /dev and optionally generate a path for
each one where they are moved temporarily when building the
namespace. And if given domain is also running it looks into its
mount table rather than at the host one. But if it did look at
the domain's private mount table, it find /dev mounted twice: the
first time by udev, the second time the tmpfs mounted by us.
Now, later in the function there's a "sorting" algorithm that
tries to reduce number of mount points needing preservation, by
identifying nested mount points. And if we keep the second
occurrence of /dev on the list, well, after the "sorting" we are
left with nothing but "/dev" because all other mount points are
nested.

The aim of qemuDomainGetPreservedMounts() is to get a list of
filesystems mounted under /dev and optionally generate a path for
each one where they are moved temporarily when building the
namespace. And the function tries to be a bit clever about it.
For instance, if /dev/shm mount point exists, there's no need to
consider /dev/shm/a nor /dev/shm/b as preserving just 'top level'
/dev/shm gives the same result. To achieve this, the function
iterates over the list of filesystem as returned by
virFileGetMountSubtree() and removes the nested ones. However, it
does so in a bit clumsy way: plain VIR_DELETE_ELEMENT() is used
without freeing the string itself. Therefore, if all three
aforementioned example paths appeared on the list, /dev/shm/a and
/dev/shm/b strings would be leaked.
And when I think about it more, there's no real need to shrink
the array down (realloc()). It's going to be free()-d when
returning from the function. Switch to
VIR_DELETE_ELEMENT_INPLACE() then.

When the 'string()' conversion is used the number is parsed inside

when 'number()' is used and libxml2 uses a 'double' variable internally.
On the upper extremes of the 64 bit variables the double precision
variable doesn't have enough precision to represent each distinct
integer and thus could cause problems.
