libxl: call EndJob in error case
If starting the domain fails in libxlDomainCreateXML, we mistakenly
jumped to cleanup without calling libxlDomainObjEndJob. Remove the
jump to 'cleanup'.

libxl: lock virDomainObj after ListRemove
Most libxl driver API use the pattern of lock and add a ref to
virDomainObj, perform API, then decrement ref and unlock in
virDomainEndAPI. In some cases the API may call
virDomainObjListRemove, which unlocks the virDomainObj. Relock
the object in such cases so EndAPI is called with a locked object.

libxl: Properly cleanup after libxlDomObjFromDomain
Commit id '9ac945078' altered libxlDomObjFromDomain to return
a locked *and* ref counted object for some specific purposes;
however, it neglected to alter all the consumers of the helper
to use virDomainObjEndAPI thus leaving many objects with extra
ref counts.

libxl: MigratePrepare: use standard begin and end API pattern
libxlDomainMigrationPrepare adds the incoming domain def to the list
of domains via virDomainObjListAdd, but never adds its own ref to the
returned virDomainObj as other callers of virDomainObjListAdd do.
libxlDomainMigrationPrepareTunnel3 suffers the same discrepancy.
Change both to add a ref to the virDomainObj after a successful
virDomainObjListAdd, similar to other callers. This ensures a consistent
pattern throughout the drivers and allows using the virDomainObjEndAPI
function for cleanup.

libxl: MigrateBegin: Dont call EndAPI in helper function
The libxlDomainMigrateBegin3Params API locks and ref counts the associated
virDomainObj but relies on the helper function libxlDomainMigrationBegin
to unref/unlock the object. libxlDomainMigrationBegin is also used by
libxlDomainMigratePerform3Params for p2p migration, but in that case the
lock/ref and unref/unlock are properly handled in the API entry point. So
p2p migrations suffer a double unref/unlock in the Perform API.
Remove the unref/unlock (virDomainObjEndAPI) from libxlDomainMigrationBegin
and adjust libxlDomainMigrateBegin3Params to properly unref/unlock
the virDomainObj on success and error paths.

libxl: don't hardcode scheduler weight
Long ago in commit dfa1e1dd53 the scheduler weight was accidentally
hardcoded to 1000. Weight is a setting with no unit since it is
relative to the weight of other domains. If no weight is specified,
libxl defaults to 256.
Instead of hardcoding the weight to 1000, honor any <shares> specified
in <cputune>. libvirt's notion of shares is synonomous to libxl's
scheduler weight setting. If shares is unspecified, defer default
weight setting to libxl.
Removing the hardcoded weight required some test fixup. While at it,
add an explicit test for <shares> conversion to scheduler weight.

commit 99486799c3f911caa009d64889fc05ec3b07f986
Author: Jim Fehlig <jfehlig@suse.com>
Date: Mon Mar 12 12:22:34 2018 -0600
libxl: MigrateConfirm: Dont unlock virDomainObj in helper function
The libxlDomainMigrateConfirm3Params API locks and ref counts the associated
virDomainObj but relies on the helper function libxlDomainMigrationConfirm
to unlock the object. Unref'ing the object is not done in either function.
libxlDomainMigrationConfirm is also used by libxlDomainMigratePerform3Params
for p2p migration, but in that case the lock/ref and unref/unlock are
properly handled in the API entry point.
Remove the unlock from libxlDomainMigrationConfirm and adjust
libxlDomainMigrateConfirm3Params to properly unref/unlock the virDomainObj
on success and error paths.

libxl: Use virDomainObjListFindBy{UUID|ID}Ref
For libxlDomainLookupByID and libxlDomainLookupByUUID let's
return a locked and referenced @vm object so that callers can
then use the common and more consistent virDomainObjEndAPI in
order to handle cleanup rather than needing to know that the
returned object is locked and calling virObjectUnlock.
The LookupByName already returns the ref counted and locked object,
so this will make things more consistent.
