ec: Add trusted.ec.dirty xattr
This xattr will be incremented before each data modifying operation and
decremented after it. This will add the possibility to detect partially
updated writes and refuse them on reads.
It will also be useful for interacting with index xlator and have a way
to heal dispersed files from the self-heal daemon.
