c250ab90ac conf: snapshot: Remove VIR_DOMAIN_SNAPSHOT_PARSE_DISKS flag
All callers except the one in the 'esx' driver pass the flag. The 'esx'
driver has a check that 'def->ndisks' is zero after parsing the
definition. This means that we can simply always parse the disks.

f24a22315b driver: Introduce global driver feature flag handling function
The 'virDrvFeature' has a combination of features which are asserted by
the specific driver and features which are actually global.

In many cases the implementation was cargo-culted into newer drivers
without re-assesing whether it makes sense.

This patch introduces a global function which will specifically handle
these global flags and defer the rest to the driver.

8eb4461645 remove sysconfig files
sysconfig files are owned by the admin of the host. They have the
liberty to put anything they want into these files. This makes it
difficult to provide different built-in defaults.

Remove the sysconfig file and place the current desired default into

Local customizations can now go either into /etc/sysconfig/name
or /etc/systemd/system/name.service.d/my-knobs.conf

Attempt to handle upgrades in libvirt.spec.
Dirty files which are marked as %config will be renamed to file.rpmsave.
To restore them automatically, move stale .rpmsave files away, and
catch any new rpmsave files in %posttrans.

5c254bb541 conf: Store SCSI bus length in virDomainDef
Libvirt assumes that a SCSI bus can fit up to 8 devices
(including controller itself), except for so called wide bus
which can accommodate up to 16 devices (again, including
controller). This plays important role when computing 'drive'
address in virDomainDiskDefAssignAddress(). So far, the only
driver that enables wide SCSI bus is VMX. But with newer
releases, ESX is capable of "super wide" bus (64 devices).

We can blindly bump the limit in our code because then we would
compute address that's invalid for older ESX versions that we
still want to support.

Unfortunately, I haven't found a better place where to store this
than virDomainDef.

c8238579fb lib: Drop internal virXXXPtr typedefs
Historically, we declared pointer type to our types:

  typedef struct _virXXX virXXX;
  typedef virXXX *virXXXPtr;

But usefulness of such declaration is questionable, at best.
Unfortunately, we can't drop every such declaration - we have to
carry some over, because they are part of public API (e.g.
virDomainPtr). But for internal types - we can do drop them and
use what every other C project uses 'virXXX *'.

This change was generated by a very ugly shell script that
generated sed script which was then called over each file in the
repository. For the shell script refer to the cover letter:
