(1) Fix SanitizeOptions() to also check HashLinkList. The current
dynamic case just happens to work because the 2 classes have the same
layout.
(2) Do not delete SliceTransform object in HashSkipListFactory and
HashLinkListFactory destructor. Reason: SanitizeOptions() enforces
prefix_extractor and SliceTransform to be the same object when
Hash**Factory is used. This makes the behavior strange: when
Hash**Factory is used, prefix_extractor will be released by RocksDB. If
other memtable factory is used, prefix_extractor should be released by
user.

Why don't we automatically reopen DB when running crash test (running in our nightly build)? If I understand correctly, crashtest is manually reopenning the DB, but then the DB does not check its consistency when you kill db_stress process and then re-run it again.
Does this make sense?

Summary:
We are going to expose properties of all tables to end users through "some" db interface.
However, current design doesn't naturally fit for this need, which is because:
1. If a table presents in table cache, we cannot simply return the reference to its table properties, because the table may be destroy after compaction (and we don't want to hold the ref of the version).
2. Copy table properties is OK, but it's slow.
Thus in this diff, I change the table reader's interface to return a shared pointer (for const table properties), instead a const refernce.

under plain table format. Changes include:
* In tools/sst_dump.cc:
- add support for plain table format
- display prefix_extractor information when --show_properties is on
* In table/format.cc
- Now the table magic number of a Footer can be later initialized
via ReadFooterFromFile().
* In table/meta_bocks:
- add function ReadTableMagicNumber() that reads the magic number of
the specified file.
Minor fixes:
- remove a duplicate #include in table/table_test.cc
- fix a commentary typo in include/rocksdb/memtablerep.h
- fix lint errors.
Test Plan:
Runs sst_dump with both block-based and plain-table format files with

1. The first one, in table/filter_block.cc is very nasty. We first reference entries_ and store the reference to Slice prev. Then, we call entries_.append(), which can change the reference. The Slice prev now points to junk.
2. The second one is a bug in a test, so it's not very serious. Once we set read_opts.prefix, we never clear it, so some other function might still reference it.

in the compressed cache. If it is found in the compressed cache,
then it is uncompressed and inserted into the uncompressed cache.
It is possible that the same block resides in the compressed cache
