cluster/ec: data heal implementation for ec
Data self-heal:
1) Take inode lock in domain 'this->name:self-heal' on 0-0 range (full file),
So that no other processes try to do self-heal at the same time.
2) Take inode lock in domain 'this->name' on 0-0 range (full file),
3) perform fxattrop+fstat and get the xattrs on all the bricks
3) Choose the brick with ec->fragment number of same version as source
4) Truncate sinks
5) Unlock lock taken in 2)
5) For each block take full file lock, Read from sources write to the sinks, Unlock
6) Take full file lock and see if the file is still sane copy i.e. File didn't become unusable while the bricks are offline.
Update mtime to before healing
7) xattrop with -ve values of 'dirty' and difference of highest and its own
version values for version xattr
8) unlock lock acquired in 6)
9) unlock lock acquired in 1)
