The methods qemuDomain{Get,Set}{Memory,Blkio,Scheduler}Parameters
all forgot to do a check on virDomainIsActive(), resulting in bogus
error messages from later parts of their impl

* src/qemu/qemu_driver.c: Add missing checks on virDomainIsActive()

sizeof(domain->name) is the wrong thing. Instead of using strdup here
rewrite escape_specialcharacters to allocate the buffer itself.

Add a contains_specialcharacters to be used in phypOpen, as phypOpen is
not interested in the escaped version.

Also fix memory leaks along the way in phypCreateServerSCSIAdapter and
phypAttachDevice.

Don't pre-allocate 4kb per key, make phypVolumeGetKey allocate the memory.

Make phypBuildVolume return the volume key instead of using pre-allocated
memory to store it.

Also fix a memory leak in phypVolumeLookupByName when phypVolumeGetKey
fails. Fix another memory leak in phypVolumeLookupByPath in the success
path. Fix phypVolumeGetXMLDesc leaking voldef.key.

Move the virInterfacePtr declaration to the top of the
function to avoid jump uninitialized variable warnings

* src/phyp/phyp_driver.c: Fix var declaration

The daemon dispatcher code had an obsolete macro

  #define REMOTE_DEBUG(fmt, ...) VIR_DEBUG(fmt, __VA_ARGS__)

This can be trivially removed

* daemon/remote.c: s/REMOTE_DEBUG/VIR_DEBUG/

Many functions did not check for whether a connection was
open. Replace the macro which obscures control flow, with
explicit checks, and ensure all dispatcher code has checks.

* daemon/remote.c: Add connection checks

Some dispatcher methods have a parameter

            remote_error *err,

Instead of the more normal

            remote_error *rerr,

* daemon/remote.c: s/err/rerr/

A lot of code in libvirtd's dispatcher used the style

    dom = get_nonnull_domain (conn, args->dom);

Instead of the normal libvirt style

    dom = get_nonnull_domain(conn, args->dom);

* daemon/remote.c: Remove all whitelist before function brackets

This is the implementation of the previous patch now using virInterface*
API. Ended up this patch got much more simpler, smaller and easier to
review. Here is some details:

  * MAC size and interface name are fixed due to specifications on HMC,
    both are created automatically and CAN'T be specified from user. They
    have the following format:

     * MAC: 122980003002
     * Interface name: U9124.720.067BE8B-V3-C0

  * I did replaced all the |grep|sed following the comments Eric Blake
    did on the last patch.

  * According to my last email, It's not possible to create a network
    interface without assigning it to a specific lpar. Then, I am using
    this very minimalistic XML file for testing:

     <interface type='ethernet' name='LPAR01'>
     </interface>

    In this file I am using "name" as the lpar name which I am going to
    assign the new network interface. I couldn't find a better way to
    refer to it. Comments are welcome.

  * Regarding the fact I am sleeping one second waiting for the HMC to
    complete creation of the interface, I don't have means to check
    if the whole process is done. All I do is execute a command, wait
    until is complete (which is not enough in this case) check
    the return and the exit status. The process of actually creating
    a networking interface seems to take a little longer than just the
    return of the ssh control.

In qemuDomainObjBeginJobWithDriver, when virCondWaitUntil timeouts,
the function tries to call qemuDriverLock with virDomainObj locked,
this causes the dead-lock problem. This patch fixes this.

Commit 9677cd33 made it possible to
remove current entry when iterating through all hash entries. However,
it didn't properly handle a special case of removing first entry
assigned to a given key which contains several entries in its collision
list.

When we take out completed calls from queue we might end up
in circular pointer. We don't want pointer to previous item
point to element taken out.

This patch adds the new options (--live, --config, and --current) to
"virsh setmaxmem" command. The behavior of above options is the same
as that of "virsh setmem".  When the --config option is specified, a
modification is effective for the persistent domain, while the --live
option is specified, a modification is effective for an active
domain. The --current option is specified, it affects a current
domain.

This patch implements the code to support virDomainSetMaxMemory API,
and to support VIR_DOMAIN_MEM_MAXIMUM flag in qemudDomainSetMemoryFlags function.
As a result, we can change the maximum memory size of inactive QEMU guests.

Move "returns" keyword from beginning of API doc lines
when it does not describe return values.
Maybe the API doc extractor could be changed to look for
"returns: " to avoid such confusion.

Aargh; commit 8ae5dfd still didn't fix the mingw problem, because
gnulib defined O_NONBLOCK to 0 for just mingw.  I've now fixed
that in gnulib, but we need the latest pipe2 for libvirt to work.

* .gnulib: Update to latest, for pipe2 fixes.

Commit 02c39a2f introduced a mingw build regression, due to a
regression in gnulib's areadlink module:

../../../gnulib/lib/careadlinkat.c: In function 'careadlinkat':
../../../gnulib/lib/careadlinkat.c:143:39: error: 'const struct allocator' has no member named 'malloc'

* .gnulib: Update to latest, for careadlinkat fix.

* tools/virsh.pod: Fix grammar, and clarify wording.
* src/qemu/qemu_driver.c (qemudDomainObjStart): Drop redundant
condition.

The libexec program libvirt_iohelper is only for libvirtd. If we build rpm
without libvirtd, we will receive the following messages:

This patch adds support for the evaluation of TCP flags in nwfilters.

It adds documentation to the web page and extends the tests as well.
Also, the nwfilter schema is extended.

The following are some example for rules using the tcp flags:

<rule action='accept' direction='in'>
    <tcp state='NONE' flags='SYN/ALL' dsptportstart='80'/>
</rule>
<rule action='drop' direction='in'>
    <tcp state='NONE' flags='SYN/ALL'/>
</rule>

This patch adds the new option (--current) to the "virsh setmem" command.
When --current option is specified, it affects a "current" domain.
The word "current" denotes that if a domain is running, it affects
a running domain only; otherwise it affects a persistent domain.

Add $localstatedir/log/libvirt/libxl when building libxenlight driver

When the new maximum memory size becomes less than the current memory size,
I think it is not the libvirt client but the each driver that decides the behavior
(reject the operation or shrink the current memory size).

It was just pointed out that, although I added documentation for the
IPv6 additions to the network XML, I neglected to use those additions
in the examples. This patch adds an IPv6 address to each of the
examples except for the "default" network, since that is a faithful
reproduction of the default network config that's automatically
installed, which doesn't include any IPv6 address (for good reason -
because there is no such thing as IPv6 NAT, there is no one IPv6
address that would work for all installations).

Libxenlight currently only supports the credit scheduler.
Therefore setting or getting a parameter of other
schedulers raise an error (for now).

1) Both "qemuDomainStartWithFlags" and "qemuAutostartDomain" try to
restore the domain from managedsave'ed image if it exists (by
invoking "qemuDomainObjRestore"), but it unlinks the image even
if restoring fails, which causes data loss. (This problem exists
for "virsh managedsave dom; virsh start dom").

The fix for is to unlink the managed state file only if restoring
succeeded.

2) For "virsh save dom; virsh restore dom;", it can cause data
corruption if one reuse the saved state file for restoring. Add
doc to tell user about it.

3) In "qemuDomainObjStart", if "managed_save" is NULL, we shouldn't
fallback to start the domain, skipping it to cleanup as a incidental
fix. Discovered by Eric.

Reattach all pci devices that we detached when qemuPrepareHostdevPCIDevices()
failed.

We should bind pci device to original driver when pciBindDeviceToStub() failed.
If the pci device is not bound to any driver before calling pciBindDeviceToStub(),
we should only unbind it from pci-stub. If it is bound to pci-stub, we should not
unbind it from pci-stub.

This patch do the following things:
1. rename the function as 'Unbind' is better than 'UnBind'.
2. pciUnbindDeviceFromStub() will be used in the function pciBindDeviceToStub() in
   next patch. Float it up, instead of having to have a forward declaration
