This file contains only a single function, detect_scsi_host_caps(),
which is declared in node_device_driver.h and called from both the hal
and udev backends. Other things common to the hal and udev drivers
can be placed in that file though. As a prelude to adding further
functions, this patch renames the existing function to something
closer in line with other internal libvirt function names
(nodeDeviceSysfsGetSCSIHostCaps()), and puts the declarations into a
separate .h file.
For some reason a union (_virNodeDevCapData) that had only been
declared inside the toplevel struct virNodeDevCapsDef was being used
as an argument to functions all over the place. Since it was only a
union, the "type" attribute wasn't necessarily sent with it. While
this works, it just seems wrong.
This patch creates a toplevel typedef for virNodeDevCapData and
virNodeDevCapDataPtr, making it a struct that has the type attribute
as a member, along with an anonymous union of everything that used to
be in union _virNodeDevCapData. This way we only have to change the
following:
s/union _virNodeDevCapData */virNodeDevCapDataPtr /
and
s/caps->type/caps->data.type/
This will make me feel less guilty when adding functions that need a
pointer to one of these.
In renaming driver API implementations to match the
public API naming scheme, a few cases in the node
device driver were missed.

In the non linux case some callers like gather_scsi_host_caps needed the
return code of -1 while others like update_caps needed an empty
statement (to avoid a "statement without effect" warning). This is much
simpler solved by using a function instead of a define.
The driver.h struct for node devices used an inconsistent
naming scheme 'DeviceMonitor' instead of the more usual
'NodeDeviceDriver'. Fix this everywhere it has leaked
out to.

This adds two util functions (virIsCapableFCHost and virIsCapableVport),
and rename helper check_fc_host_linux as detect_scsi_host_caps,
check_capable_vport_linux is removed, as it's abstracted to the util
function virIsCapableVport. detect_scsi_host_caps nows detect both
the fc_host and vport_ops capabilities. "stat(2)" is replaced with
"access(2)" for saving.
* src/util/virutil.h:
- Declare virIsCapableFCHost and virIsCapableVport
* src/util/virutil.c:
- Implement virIsCapableFCHost and virIsCapableVport
* src/node_device/node_device_linux_sysfs.c:
- Remove check_capable_vport_linux
- Rename check_fc_host_linux as detect_scsi_host_caps, and refactor
it a bit to detect both fc_host and vport_os capabilities
* src/node_device/node_device_driver.h:
- Change/remove the related declarations
* src/node_device/node_device_udev.c: (Use detect_scsi_host_caps)
* src/node_device/node_device_hal.c: (Likewise)
* src/node_device/node_device_driver.c (Likewise)
"open_wwn_file" in node_device_linux_sysfs.c is redundant, on one
hand it duplicates work of virFileReadAll, on the other hand, it's
waste to use a function for it, as there is no other users of it.
So I don't see why the file opening work cannot be done in
"read_wwn_linux".
"read_wwn_linux" can be abstracted as an util function. As what all
it does is to read the sysfs entry.
So this patch removes "open_wwn_file", and abstract "read_wwn_linux"
as an util function "virReadFCHost" (a more general name, because
after changes, it can read each of the fc_host entry now).
* src/util/virutil.h: (Declare virReadFCHost)
* src/util/virutil.c: (Implement virReadFCHost)
* src/node_device/node_device_linux_sysfs.c: (Remove open_wwn_file,
and read_wwn_linux)
src/node_device/node_device_driver.h: (Remove the declaration of
read_wwn_linux, and the related macros)
src/libvirt_private.syms: (Export virReadFCHost)
This just simply changes nodeDeviceLookupByWWN to be not static,
and its name into nodeDeviceLookupSCSIHostByWWN. And use that for
udev and HAL backends.

Except a bunch of files for security driver, all others are changed

This patch moves some of the sriov related pci code from node_device driver
to src/util/pci.[ch]. Some functions had to go thru name and argument list
change to accommodate the move.

Some kernels, such as the one used in RHEL-5, have vport_create and
vport_delete operation files in /sys/class/scsi_host/hostN directory
instead of /sys/class/fc_host/hostN. Let's check both paths for
compatibility reasons.
This also removes unnecessary '/' characters from sysfs paths containing
LINUX_SYSFS_FC_HOST_PREFIX.
