371c15517c nodedev: fix vport detection for FC HBA
Use the host number as the host number when constructing the sysfs path
instead of the variable we are trying to fill.

c56c273be6 util: Change virIsCapable* to return bool
Function name with "aIsB" generally means its return value is
in Bi-state (true/false).

58662f4416 Make detect_scsi_host_caps a function on all architectures
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.

7c9a2d88cd virutil: Move string related functions to virstring.c
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.

448be8f706 nodedev: Dump max vports and vports in use for HBA's XML
This enrichs HBA's xml by dumping the number of max vports and
vports in use. Format is like:

  <capability type='vport_ops'>
    <max_vports>164</max_vports>
    <vports>5</vports>
  </capability>

  max_vports and vports)

4360a09844 nodedev: Refactor the helpers
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)

244ce462e2 util: Add one helper virReadFCHost to read the value of fc_host entry
"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)

cc17f09246 npiv: Expose fabric_name outside
This patch is to expose the fabric_name of fc_host class, which
might be useful for users who wants to known which fabric the
(v)HBA connects to.

The patch also adds the missed capabilities' XML schema of scsi_host,
(of course, with fabric_wwn added), and update the documents
(docs/formatnode.html.in)

b65f37a4a1 libvirt,logging: cleanup VIR_XXX0()
These VIR_XXXX0 APIs make us confused, use the non-0-suffix APIs instead.

How do these coversions works? The magic is using the gcc extension of ##.
When __VA_ARGS__ is empty, "##" will swallow the "," in "fmt," to
avoid compile error.

example: origin				after CPP
	high_level_api("%d", a_int)	low_level_api("%d", a_int)
	high_level_api("a  string")	low_level_api("a  string")

About 400 conversions.

8 special conversions:
VIR_XXXX0("") -> VIR_XXXX("msg") (avoid empty format) 2 conversions
VIR_XXXX0(string_literal_with_%) -> VIR_XXXX(%->%%) 0 conversions
VIR_XXXX0(non_string_literal) -> VIR_XXXX("%s", non_string_literal)
  (for security) 6 conversions

60ae1c34ad bye to close(), welcome to VIR_(FORCE_)CLOSE()
Using automated replacement with sed and editing I have now replaced all
occurrences of close() with VIR_(FORCE_)CLOSE() except for one, of
course. Some replacements were straight forward, others I needed to pay
attention. I hope I payed attention in all the right places... Please
have a look. This should have at least solved one more double-close
error.

b31ef77313 nodedev: Fix sysfs paths for vport operations
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.
