* Convert function local statics in option helper to a C array

Added 2 statistics in compaction job statistics, to
identify if single deletes are not meeting a matching key
(fallthrough) or single deletes are meeting a merge, delete or
another single delete (i.e. not the expected case of put).

Summary:
Add API to WriteBatch to store range deletions in its buffer
which are later added to memtable. In the WriteBatch buffer, a range
deletion is encoded as "<optype><CF ID (optional)><begin key><end key>".
With this diff, the range tombstones are stored inline with the data in
the memtable. It's useful for now because the test cases rely on the
data being accessible via memtable. My next step is to store range
tombstones in a separate area in the memtable.

Summary:
We were frequently seeing a race between SyncPoint::Process() and
SyncPoint::~SyncPoint() (e.g.,
https://our.intern.facebook.com/intern/sandcastle/log/?instance_id=207289975&step_id=2412725431).
The issue was marked_thread_id_ gets deleted when the main thread is exiting and
simultaneously background threads may access it. We can prevent this race
condition by checking whether sync points are disabled (assuming the test terminates
with them disabled) before attempting to access that member. I do not understand
why accesses to other members (mutex_ and enabled_) are ok but anyways the
test no longer fails tsan.

Summary:
Env holds a pointer of ThreadStatusUpdater, which will be deleted when
Env is deleted. However, in case a rocksdb database is deleted after
Env is deleted. Then this will introduce a free-after-use of this
ThreadStatusUpdater.
This patch fix this by never deleting the ThreadStatusUpdater in Env,
which is in general safe as Env is a singleton in most cases.

Summary:
This is a proof of concept of a RocksDB blob log file. The actual value of the Put() is appended to a blob log using normal data block format, and the handle of the block is written as the value of the key in RocksDB.
The prototype only supports Put() and Get(). It doesn't support DB restart, garbage collection, Write() call, iterator, snapshots, etc.

From the Linux manual:
MAP_ANONYMOUS
The mapping is not backed by any file; its contents
are initialized to zero. The fd and offset arguments are
ignored; however, some implementations require fd to be -1
if MAP_ANONYMOUS (or MAP_ANON) is specified, and portable
applications should ensure this.
FreeBSD is such a case, it wil just return an error.
