naivewong dd0d3c6f02 Several small fixes (#550) 
`if ds[i].meta.MinTime < t0 || ds[i].meta.MaxTime > t0+tr `, ds[i].meta.MinTime is always larger or equal to t0, so no need for this check.
`ulid.Parse` only checks if the length is 26. So changed to  using `ulid.ParseStrict` to also check the validity of ulid.

Goutham Veeramachaneni 10d395259b Avoid creation of 0 sized segments. (#527) 
If the corrupt segment is full, then we set donePages on open,
c59ed492b2/wal/wal.go (L235-L243)

Then when we try to repair, we set the segment to be a new segment but
we don't update the donePages: c59ed492b2/wal/wal.go (L334)

We we try to log to this, because donePages is full, we will never log
anything to this segment and create a new one: c59ed492b2/wal/wal.go (L486)

This does not cause issues because we simply concatenate the segments on
read, there by transparently skipping this `0b` segment.

LiveReader can get into an infinite loop on corrupt WALs. (#524) 
Make WAL live tailer return EOF when the there is a half-written record at the end of the file.

Previously, this would cause an infinite loop as we ignored EOFs when filling the buffer.  We now differentiate between EOFs that read >0 bytes, and EOFs that didn't.

Add some more unit tests for tailing a corrupt WAL, and unify interfaces Reader and LiveReader for the purposes of testing.
