Recent changes uncovered FORWARD_NULL and NEGATIVE_RETURNS problems with
the processing of the 'ndevices' and its associated allocated arrays in
'vshNodeDeviceListCollect' due to the possibility of returning -1 in a
call and using the returned value as a for loop index end condition.
Convert the type of loop iterators named 'i', 'j', k',
'ii', 'jj', 'kk', to be 'size_t' instead of 'int' or
'unsigned int', also santizing 'ii', 'jj', 'kk' to use
the normal 'i', 'j', 'k' naming

These all existed before virfile.c was created, and for some reason
weren't moved.
This is mostly straightfoward, although the syntax rule prohibiting
write() had to be changed to have an exception for virfile.c instead
of virutil.c.
This movement pointed out that there is a function called
virBuildPath(), and another almost identical function called
virFileBuildPath(). They really should be a single function, which
I'll take care of as soon as I figure out what the arglist should look
like.
The source code base needs to be adapted as well. Some files
include virutil.h just for the string related functions (here,
the include is substituted to match the new file), some include
virutil.h without any need (here, the include is removed), and
some require both.
The virsh nodedev-detach command has a new --driver option. If it's
given virsh will attempt to use the new virNodeDeviceDetachFlags API
instead of virNodeDeviceDettach. Validation of the driver name string
is left to the hypervisor (qemu accepts "kvm" or "vfio". The only
other hypervisor that implements these functions is xen, and it only
accepts NULL).
VIR_CONNECT_LIST_NODE_DEVICES_CAP_FC_HOST to filter the FC HBA,
and VIR_CONNECT_LIST_NODE_DEVICES_CAP_VPORTS to filter the FC HBA
which supports vport.
After we switched to C99 initialization, I noticed there were many
places where the specification of .flags parameter differed. After
going through many options and deciding whether to unify the
initialization to be '.flags = 0' or '.flags = VSH_OFLAG_NONE', I
realized both can be removed and it makes the code easier to go
through.
Only nodedev-destroy and nodedev-dumpxml can benifit from the
new API, other commands like nodedev-detach only works for
PCI devices, WWN makes no sense for them.
This patch adds some empty lines to separate blocks of code, cleans up
unnecessary error message constructs in cmdNodeDeviceDetach,
cmdNodeDeviceReAttach, cmdNodeDeviceReset and refactors error paths in
cmdNodeDeviceDumpXML.
The libvirt coding standard is to use 'function(...args...)'
instead of 'function (...args...)'. A non-trivial number of
places did not follow this rule and are fixed in this patch.

* tests/securityselinuxhelper.c: Remove doubled line.
* tests/securityselinuxtest.c: Likewise.
* globally: s/; If/. If/
tools/virsh-nodedev.c:
* vshNodeDeviceSorter to sort node devices by name
* vshNodeDeviceListFree to free the node device objects list.
* vshNodeDeviceListCollect to collect the node device objects, trying
to use new API first, fall back to older APIs if it's not supported.
* Change option --cap to accept multiple capability types.
tools/virsh.pod
* Update document for --cap
Now that vshCommandRun() checks for the connection automaticaly, remove
all of the redundant checks in the code.
vshConnectionUsability() no longer needs to be exported and this patch
marks it static.
Another worthwhile split, needed one more public function.
* tools/virsh-nodedev.h: New file.
* tools/Makefile.am (virsh_SOURCES): Build it.
* tools/virsh-nodedev.c: Use new header.
* tools/virsh.c: Likewise.
(vshTreePrint): Export.
* tools/virsh.h (vshTreePrint): Declare.
Commands in node device group moved from virsh.c to virsh-nodedev.c,
* virsh.c: Remove commands in node device group.
* virsh-nodedev.c: New file, filled with commands in node device group
* po/POTFILES.in: Add virsh-nodedev.c
* cfg.mk: Skip to check config.h including for virsh-nodedev.c
