qemu: event: Don't fiddle with disk backing trees without a job

Surprisingly we did not grab a VM job when a block job finished and we'd
happily rewrite the backing chain data. This made it possible to crash
libvirt when queueing two backing chains tightly and other badness.

To fix it, add yet another handler to the helper thread that handles
monitor events that require a job.

qemu: Check for negative port values in network drive configuration

We interpret port values as signed int (convert them from char *),
so if a negative value is provided in network disk's configuration,
we accept it as valid, however there's an 'unknown cause' error raised later.
This error is only accidental because we return the port value in the return code.
This patch adds just a minor tweak to the already existing check so we
reject negative values the same way as we reject non-numerical strings.

util: don't fail if no PortData is found while getting migrateData

Introduced by f6a2f97e

Problem Description:
After multiple times of migrating a domain, which has an ovs interface with no portData set,
with non-shared disk, nbd ports got overflowed.

The steps to reproduce the problem:
1 define and start a domain with its network configured as:
    <interface type='bridge'>
          <source bridge='br0'/>
          <virtualport type='openvswitch'>
          </virtualport>
          <model type='virtio'/>
          <driver name='vhost' queues='4'/>
    </interface>
2 do not set the network's portData.
3 migrate(ToURI2) it with flag 91(1011011), which means:
  VIR_MIGRATE_LIVE
  VIR_MIGRATE_PEER2PEER
  VIR_MIGRATE_PERSIST_DEST
  VIR_MIGRATE_UNDEFINE_SOURCE
  VIR_MIGRATE_NON_SHARED_DISK
4 migrate success, but we got an error log in libvirtd.log:
  error : virCommandWait:2423 : internal error: Child process (ovs-vsctl --timeout=5 get Interface
  vnet1 external_ids:PortData) unexpected exit status 1: ovs-vsctl: no key "PortData" in Interface
  record "vnet1" column external_ids
5 migrate it back, migrate it , migrate it back, .......
6 nbd port got overflowed.

The reasons for the problem is :
1 virNetDevOpenvswitchGetMigrateData() takes it as wrong if no portData is available for  the ovs
 interface of a domain. (We think it's not appropriate, as portData is just OPTIONAL)
2 in func qemuMigrationBakeCookie(), it fails in qemuMigrationCookieAddNetwork(), and returns with -1.
 qemuMigrationCookieAddNBD() is not called thereafter, and mig->nbd is still NULL.
3 However, qemuMigrationRun() just *WARN* if qemuMigrationBakeCookie() fails, migration still successes.
 cookie is NULL, it's not baked on the src side.
4 On the destination side, it would alloc a port first and then free the nbd port in COOKIE.
 But the cookie is NULL due to qemuMigrationCookieAddNetwork() failure at src side. thus the nbd port
 is not freed.

In this patch, we add "--if-exists" option to make ovs-vsctl not raise error if there's no portData available.
Further more, because portData may be NULL in the cookie at the dest side, check it before setting portData.

As of bba93d40 all of our RPC objects are derived from
virObjectLockable. However, during rewrite some errors sneaked
in. For instance, the dispose functions to virNetClient and
virNetServerClient objects were not only freeing allocated
memory, but unlocking themselves. This is wrong. Object should
never disappear while locked.

Commit v1.2.4-52-gda879e5 fixed issues with domains started before
sanlock driver was enabled by checking whether a running domain is
registered with sanlock and if it's not, sanlock driver is basically
ignored for the domain.

However, it was checking this even for domain which has just been
started and no sanlock_* API was called for them yet. This results in

    cmd 9 target pid 2135544 not found

error messages to appear in sanlock.log whenever we start a new domain.
