Summary: So iOS size_t is 32-bit, so we need to static_cast<size_t> any uint64_t :(

Summary:
We need to turn on -Wshorten-64-to-32 for mobile. See D1671432 (internal phabricator) for details.
This diff turns on the warning flag and fixes all the errors. There were also some interesting errors that I might call bugs, especially in plain table. Going forward, I think it makes sense to have this flag turned on and be very very careful when converting 64-bit to 32-bit variables.

Summary:
ColumnFamilyHandles face the same problem as RocksIterator previously
so used methods were also applied for ColumnFamilyHandles.
Another problem with CF was that Options passed to CFs were
always filled with default values. To enable Merge, all parts
of the database must share the same merge functionality which
is not possible using default values. So from now on every
CF will inherit from db options.
Changes to RocksDB:
- merge can now take also a cfhandle
Changes to MergeTest:
- Corrected formatting
- Included also GC tests
- Extended tests to cover CF related parts
- Corrected paths to cleanup properly within the test process
- Reduced verbosity of the test

Summary:
Options extends now two interfaces DBOptionsInterface
and ColumnFamilyOptionsInterface. There are also further
improvements to the Options bindings:
Optimize methods were ported to Java. (OptimizeForPointLookup,
OptimizeLevelCompaction, OptimizeUniversalCompaction).
To align BuiltinComparator with every other Enum it was moved to
a separate file.

Summary:

- BackupableDB purgeOldBackups bugfix
- BackupInfos now available in Restorable-/BackupableDB
- Extended BackupableDBTest to cover more of the currently implemented functionality.

RocksIterator will sometimes Sigsegv on dispose. Mainly thats related
to dispose order. If the related RocksDB instance is freed beforehand
RocksIterator.dispose() will fail.
Within this commit there is a major change to RocksIterator. RocksIterator
will hold a private reference to the RocksDB instance which created the
RocksIterator. So even if RocksDB is freed in the same GC cycle the
RocksIterator instances will be freed prior to related RocksDB instances.
Another aspect targets the dispose logic if the RocksDB is freed previously
and already gc`ed. On dispose of a RocksIterator the dispose logic will check
if the RocksDB instance points to an initialized DB. If not the dispose logic
will not perform any further action.
The crash can be reproduced by using the related test provided within this
commit.
Related information: This relates to @adamretter`s facebook rocksdb-dev group
post about SigSegv on RocksIterator.dispose().

- releaseSnapshot
- ReadOptions support to set a Snapshot
- ReadOptions support to retrieve Snapshot
- SnapshotTest
