In our config files users are expected to pass several integer values
for different configuration knobs. However, majority of them expect a
nonnegative number and only a few of them accept a negative number too
(notably keepalive_interval in libvirtd.conf).
Therefore, a new type to config value is introduced: VIR_CONF_ULONG
that is set whenever an integer is positive or zero. With this
approach knobs accepting VIR_CONF_LONG should accept VIR_CONF_ULONG
too.

Since virNetworkFree will call virObjectUnref anyway, let's just use that
directly so as to avoid the possibility that we inadvertently clear out
a pending error message when using the public API.
Up to now, users can configure BIOS via the <loader/> element. With
the upcoming implementation of UEFI this is not enough as BIOS and
UEFI are conceptually different. For instance, while BIOS is ROM, UEFI
is programmable flash (although all writes to code section are
denied). Therefore we need new attribute @type which will
differentiate the two. Then, new attribute @readonly is introduced to
reflect the fact that some images are RO.
Moreover, the OVMF (which is going to be used mostly), works in two
modes:
1) Code and UEFI variable store is mixed in one file.
2) Code and UEFI variable store is separated in two files
The latter has advantage of updating the UEFI code without losing the
configuration. However, in order to represent the latter case we need
yet another XML element: <nvram/>. Currently, it has no additional
attributes, it's just a bare element containing path to the variable
store file.

The usual portability fixes; and this includes a fix that adds
a new syntax check for double semicolons (commit 28de556 fixed
some, but gnulib found a better check).
* .gnulib: Update to latest.
* src/xenconfig/xen_common.c (xenFormatConfigCommon): Fix offender.

If virDomainDiskDefFree(disk) is called in 'skipdisk:', then it's possible
to either return to skipdisk without reallocating a new disk (via the if
condition just prior) or to end the loop having deleted the disk. Since
virDomainDiskDefFree() does not pass by reference, disk isn't changed in
this context, thus the possible issue.
There were two warnings in this module
If the VIR_ALLOC_N(def->serials, 1) fails, then a virDomainChrDefFree(chr)
is called and we jump to cleanup which makes the same call. Just remove
the one after VIR_ALLOC_N()
In the label "skipnic:" a virDomainNetDefFree(net) is made; however, if
in going back to the top of the loop we jump back down to skipnic for any
reason, the call will attempt to free an already freed structure since
"net" was not passed by reference to virDomainNetDefFree(). Just set
net = NULL in skipnic: to resolve the issue.
Since '337a13628' - Coverity complains that 'net' is VIR_ALLOC()'d, but
on various 'cleanup' exit paths from the code there is no corresponding
cleanup.
XM and XL config are very similar. Disks are specified differently
in XL, but the old XM disk config is still supported by XL. XL also
supports new config like spice that was never supported by XM.
This patch moves all the common parsing and formatting functions to
the new file xen_common.c and adapts the XM parser/formatter accordingly.
This restructuring paves way for introducing an XL parser/formatter in
the future.
While moving the code, fixup whitespace, comments, and style issues.
