Previously the `SelectSegments` changed to clone all return value
preventing possible update to returned info.
Since meta is implemented following COW rules, this shall not happen and
any update on segment shall have copy before it.
This PR:
- Remove clone for read-only Get segment info
- Add Segment Operator abstraction for changing segment
- Implemnt COW for updating MaxRowNum

Compaction would copy logPaths from comapctFrom segA to compactTo segB,
and previous code would copy the logPath directly, causing there're
full-logPaths-of-segA in compactTo segB's meta. So, for the next
compaction of segB, if segA has been GCed, Download would report error
"The sperified key not found".
This PR makes sure compactTo segment's meta contains logID only. And
this PR also refines CompleteComapctionMutation, increasing some
readability and merge two methods into one.
