Commit 6b9964 enforces checking invalid use of VSH_OT_STRING with
VSH_OFLAG_REQ. This commit tries to do the same thing to stop using
VSH_OT_DATA without VSH_OFLAG_REQ and also fix existing misuse.

Add the optional adapter options for pool create/define. Results in
either:
<adapter type='scsi_host' name='scsi_host2'/>
or (on one line)
<adapter type='fc_host' parent='scsi_host5'
wwnn='20000000c9831b4b' wwpn='10000000c9831b4b'/>
being generated.
Add 3 new optional options for the pool-create-as and pool-define-as
command in order to define the 3 elements required in order to add
an auth element, such as:
<auth type='chap' username='myuser'>
<secret usage='libvirtiscsi'/>
</auth>
According to comments in parsing functions, optional options should be
specified *after* required ones. It makes sense and help output looks
cleaner. The only exceptions are options with type == VSH_OT_ARGV.

Since 0766783abb
Coverity complains that the EDIT_FREE definition results in DEADCODE.
As it turns out with the change to use the EDIT_FREE macro the call to
vir*Free() wouldn't be necessary nor would it happen...
Prior code to above commitid would :
vir*Ptr foo = NULL;
...
foo = vir*GetXMLDesc()
...
vir*Free(foo);
foo = vir*DefineXML()
...
And thus the free was needed. With the change to use EDIT_FREE the
same code changed to:
vir*Ptr foo = NULL;
vir*Ptr foo_edited = NULL;
...
foo = vir*GetXMLDesc()
...
if (foo_edited)
vir*Free(foo_edited);
foo_edited = vir*DefineXML()
...
However, foo_edited could never be set in the code path - even with
all the goto's since the only way for it to be set is if vir*DefineXML()
succeeds in which case the code to allow a retry (and thus all the goto's)
never leaves foo_edited set
All error paths lead to "cleanup:" which causes both foo and foo_edited
to call the respective vir*Free() routines if set.

Implement ZFS storage backend driver. Currently supported
only on FreeBSD because of ZFS limitations on Linux.
Features supported:
- pool-start, pool-stop
- pool-info
- vol-list
- vol-create / vol-delete
Pool definition looks like that:
<pool type='zfs'>
<name>myzfspool</name>
<source>
<name>actualpoolname</name>
</source>
</pool>
The 'actualpoolname' value is a name of the pool on the system,
such as shown by 'zpool list' command. Target makes no sense
here because volumes path is always /dev/zvol/$poolname/$volname.
User has to create a pool on his own, this driver doesn't
support pool creation currently.
A volume could be used with Qemu by adding an entry like this:
<disk type='volume' device='disk'>
<driver name='qemu' type='raw'/>
<source pool='myzfspool' volume='vol5'/>
<target dev='hdc' bus='ide'/>
</disk>
In "src/conf/" there are many enumeration (enum) declarations.
Similar to the recent cleanup to "src/util" directory, it's
better to use a typedef for variable types, function types and
other usages. Other enumeration and folders will be changed to
typedef's in the future. Most of the files changed in this
commit are related to storage (storage_conf) enums.

Commit a1cbe4b5 added a check for spaces around assignments and this
patch extends it to checks for spaces around '=='. One exception is
virAssertCmpInt where comma after '==' is acceptable (since it is a
macro and '==' is its argument).

I noticed this while shortening switch statements via VIR_ENUM.
Basically, the only ways virAsprintf can fail are if we pass a
bogus format string (but we're not THAT bad) or if we run out
of memory (but it already warns on our behalf in that case).
Throw away the cruft that tries too hard to diagnose a printf
failure.

Dan Berrange suggested that using VIR_ENUM_IMPL is more compact
than open-coding switch statements, and still just as forceful
at making us remember to update lists if we add enum values
in the future. Make this change throughout virsh.
Sure enough, doing this change caught that we missed at least
VIR_STORAGE_VOL_NETDIR.

Recent addition of the gluster pool type omitted fixing the virsh and
virConnectListAllStoragePool filters. A typecast of the converting
function in virsh showed that also the sheepdog pool was omitted in the
command parser.
This patch adds gluster pool filtering support and fixes virsh to
properly convert all supported storage pool types. The added typecast
should avoid doing such mistakes in the future.
Change the alignment to match the domain listing function.

At a slightly larger memory expense allow stealing of items from the
string array returned from vshStringToArray and turn the result into a
string list compatible with virStringSplit. This will allow to use the
common dealloc function.
This patch also fixes a few forgotten checks of return from
vshStringToArray and one memory leak.
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.
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.
On error, virStoragePoolGetAutostart would return -1 leaving autostart
untouched.
Removed the misleading debug message as well.
Error: CHECKED_RETURN (CWE-252):
libvirt-0.10.2/tools/virsh-pool.c:1386: unchecked_value: No check of the
return value of "virStoragePoolGetAutostart(pool, &autostart)".
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.

the returned pool list by whether the pool is persistent or not.
--autostart or --no-autostart is to filter the returned pool list
by whether the pool is autostarting or not. --type is to filter
the pools by pool types. E.g.

Virsh uses an error handler to save errors from libvirt. On some code

was used.
