Summary:
This is first step of my effort to reduce size of librocksdb.a for use in mobile.
ldb object files are huge and are ment to be used as a command line tool. I moved them to `tools/` directory and include them only when compiling `ldb`
This diff reduced librocksdb.a from 42MB to 39MB on my mac (not stripped).

We should clean up after ourselves. Last crashtest failed because the disk on the cibuild machine was full.
Also, db_crashtest is supposed to run the test on the same database in every iteration. This isn't the case currently, because every run creates a new tmp directory. It's fixed with this diff.

Summary:
(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.

Summary:
@kailiu mentioned on meeting yesterday that we sometimes have trouble opening DB created by old version with the new version. This will be very important to test for column families, since I'm changing disk format for the MANIFEST.
I added a tool that can help us test that. Usage:
./db_sanity_test <path> create
will create a bunch of DBs under <path>
<change RocksDB version>
./db_sanity_test <path> verify
will verify consistency of DBs created under <path>

Summary:
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.

Summary:
This diff enables the command line tool `sst_dump` to work for sst files
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
different arguments, specifically those with --show-properties and --from.
