[libvirt] [PATCH 0/4] storage: Fix VolOpen error reporting

[Cole Robinson]

In https://bugzilla.redhat.com/show_bug.cgi?id=1080613 , something is
causing StorageVolGetXML to fail, but it's not raising any error message.
Code inspection found that most users of VolOpen are susceptible to error
reporting issues.

The first 3 patches are some code reorganization and cleanups that make
it easier to identify the VolOpen callers. Patch 4 fixes up the reporting
issue.

Cole Robinson (4):
  storage: Rename UpdateVolInfoFlags to UpdateVolInfo
  storage: move block format lookup to shared UpdateVolInfo
  storage: Rename VolOpenCheckMode to VolOpen
  storage: Always report an error from VolOpen
