d97a72d63f Try to repair db with wal_dir option, avoid leak some WAL files
Summary:
We should search wal_dir in Repairer::FindFiles function, and avoid use
LogFileNmae(dbname, number) to get WAL file's name, which will get a wrong
WAL filename. as following:

```
[WARN] [/home/liuchang/Workspace/rocksdb/db/repair.cc:310] Log #3: ignoring conversion error: IO error: While opening a file for sequentially reading: /tmp/rocksdbtest-1000/repair_test/000003.log: No such file or directory
```
  I have added a new test case to repair_test.cc, which try to repair db with all WAL options.

3b7ed677de ColumnFamilyOptions API [CF + RepairDB part 3/3]
Summary:
Overload RepairDB to take vector-of-ColumnFamilyDescriptor, which tells
us CF name + options. Also takes a ColumnFamilyOptions for unspecified column
families encountered during the repair.

One potentially confusing thing is that we store options in the constructor and
don't invoke AddColumnFamily() until discovering the CF in ScanTable. This is
because we don't know the CF ID until we find a table belonging to that CF.

Depends on D59781.

Test Plan:
  $ ./repair_test

56ac686292 Detect column family from properties [CF + RepairDB part 2/3]
Summary:
This diff uses the CF ID and CF name properties in the SST file
to associate recovered data with the proper column family. Depends on D59775.

- In ScanTable(), create column families in VersionSet each time a new one is discovered (via reading SST file properties)
- In ConvertLogToTable(), dump an SST file for every column family with data in the WAL
- In AddTables(), make a VersionEdit per-column family that adds all of that CF's tables

Test Plan:
  $ ./repair_test

343507afb1 Refactor to use VersionSet [CF + RepairDB part 1/3]
Summary:
To support column families, it is easiest to use VersionSet to manage
our column families (if we don't have Versions then ColumnFamilyData always
behaves as a dummy column family). This diff only refactors the existing repair
logic to use VersionSet; the next two parts will add support for multiple
column families.

Test Plan:
  $ ./repair_test

e182f03c1e Add unit tests for RepairDB
Summary:
Basic test cases:

- Manifest is lost or corrupt
- Manifest refers to too many or too few SST files
- SST file is corrupt
- Unflushed data is present when RepairDB is called

Depends on D55065 for its CreateFile() function in file_utils

Test Plan: Ran the tests.
