Kevin Wolf - Sept. 28, 2012, 5:57 p.m.
From: Paolo Bonzini <pbonzini@redhat.com>

We want to remove knowledge of BLOCK_ERR_STOP_ENOSPC from drivers;
drivers should only be told whether to stop/report/ignore the error.
On the other hand, we want to keep using the nicer BlockErrorAction
name in the drivers.  So rename the enums, while leaving aside the
names of the enum values for now.
