1. Updated HISTORY.md to include this API change of DB::OpenForReadOnly;
2. Updated the help information for the put and batchput subcommands of ldb with the option [--create_if_missing];
3. Updated the comment of Env::DeleteDir to emphasize that it returns OK only if the directory to be deleted is empty.

Summary:
The patch cleans up the code and improves the consistency checks around
adding/deleting table files in `VersionBuilder`. Namely, it makes the checks
stricter and improves them in the following ways:
1) A table file can now only be deleted from the LSM tree using the level it
resides on. Earlier, there was some unnecessary wiggle room for
trivially moved files (they could be deleted using a lower level number than
the actual one).
2) A table file cannot be added to the tree if it is already present in the tree
on any level (not just the target level). The earlier code only had an assertion
(which is a no-op in release builds) that the newly added file is not already
present on the target level.
3) The above consistency checks around state transitions are now mandatory,
as opposed to the earlier `CheckConsistencyForDeletes`, which was a no-op
in release mode unless `force_consistency_checks` was set to `true`. The rationale
here is that assuming that the initial state is consistent, a valid transition leads to a
next state that is also consistent; however, an *invalid* transition offers no such
guarantee. Hence it makes sense to validate the transitions unconditionally,
and save `force_consistency_checks` for the paranoid checks that re-validate
the entire state.
4) The new checks build on the mechanism introduced in https://github.com/facebook/rocksdb/pull/6862,
which enables us to efficiently look up the location (level and position within level)
of files in a `Version` by file number. This makes the consistency checks much more
efficient than the earlier `CheckConsistencyForDeletes`, which essentially
performed a linear search.

Summary:
Because ARM and some other platforms have a larger cache line
size, they have a larger minimum filter size, which causes recently
added PartitionedMultiGet test in db_bloom_filter_test to fail on those
platforms. The code would actually end up using larger partitions,
because keys_per_partition_ would be 0 and never == number of keys
added.
The code now attempts to get as close as possible to the small target
size, while fully utilizing that filter size, if the target partition
size is smaller than the minimum filter size.

Summary:
The implementation of GetApproximateSizes was inconsistent in
its treatment of the size of non-data blocks of SST files, sometimes
including and sometimes now. This was at its worst with large portion
of table file used by filters and querying a small range that crossed
a table boundary: the size estimate would include large filter size.
It's conceivable that someone might want only to know the size in terms
of data blocks, but I believe that's unlikely enough to ignore for now.
Similarly, there's no evidence the internal function AppoximateOffsetOf
is used for anything other than a one-sided ApproximateSize, so I intend
to refactor to remove redundancy in a follow-up commit.
So to fix this, GetApproximateSizes (and implementation details
ApproximateSize and ApproximateOffsetOf) now consistently include in
their returned sizes a portion of table file metadata (incl filters
and indexes) based on the size portion of the data blocks in range. In
other words, if a key range covers data blocks that are X% by size of all
the table's data blocks, returned approximate size is X% of the total
file size. It would technically be more accurate to attribute metadata
based on number of keys, but that's not computationally efficient with
data available and rarely a meaningful difference.
Also includes miscellaneous comment improvements / clarifications.
Also included is a new approximatesizerandom benchmark for db_bench.
No significant performance difference seen with this change, whether ~700 ops/sec with cache_index_and_filter_blocks and small cache or ~150k ops/sec without cache_index_and_filter_blocks.

`IterKey::UpdateInternalKey()` is an error-prone API as it's

buffer when needed. The logic for safely getting a Slice with global
seqno properly assigned is encapsulated in `GlobalSeqnoAppliedKey`.
`BinarySeek()` is also migrated to use this API (previously it ignored
global seqno entirely).

Summary:
Preliminary user-timestamp support for delete.
If ["a", ts=100] exists, you can delete it by calling `DB::Delete(write_options, key)` in which `write_options.timestamp` points to a `ts` higher than 100.
Implementation
A new ValueType, i.e. `kTypeDeletionWithTimestamp` is added for deletion marker with timestamp.
The reason for a separate `kTypeDeletionWithTimestamp`: RocksDB may drop tombstones (keys with kTypeDeletion) when compacting them to the bottom level. This is OK and useful if timestamp is disabled. When timestamp is enabled, should we still reuse `kTypeDeletion`, we may drop the tombstone with a more recent timestamp, causing deleted keys to re-appear.

somehow the windows-server-2019-vs2019 image changed in a way that made
VS 14 2015 the default. This caused an error when we specify VS 16 2019
as the cmake generator. I could not figure out the right arguments/env
vars to get the latest VS working so pinned the image to the previous
version instead.

Summary:
Fixed some option handling code that recently broke the
ASSERT_STATUS_CHECKED build for options_test.
Added all other existing tests that pass under ASSERT_STATUS_CHECKED to
the whitelist.
Added a Travis configuration to run all whitelisted tests with
ASSERT_STATUS_CHECKED. (Someday we might enable this check by default in
debug builds.)

Summary:
Previously in LITE mode, an autovector did not have a reserved size. When
elements were added to the vector, the underlying array could be reallocated.
There was a set of code that never expands the autovector and was doing &autovector::back(). When the vector is resized, the old addresses may become invalid, causing a later exception to be thrown.
By reserving space in the autovector up front, this problem is eliminated for those uses where the vector will never exceed the initial size.
the resize happens, these pointers become invalid, leading to SEGV or other exceptions.
This change allows the autovector to be fully populated before we take the address of any of its elements, thereby elminating the potential for a resize.
There is comparable code to this change in Version::MultiGet for dealing with the context objects.

unsupported in lite builds.

Summary:
Added code for generically handing structs to OptionTypeInfo. A struct is a collection of variables handled by their own map of OptionTypeInfos. Examples of structs include Compaction and Cache options.
