Summary:
Release code now depends on gtest, indirectly through including "test_util/testharness.h". This creates multiple problems. One important reason is the definition of IGNORE_STATUS_IF_ERROR() in test_util/testharness.h. Move it to sync_point.h instead.
Note that utilities/cassandra/format.h still depends on "test_util/testharness.h". This will be resolved in a separate diff.

Summary:
Currently we rely on `BlockContents` to implicitly free the allocated scratch buffer, but when IO error happens, it doesn't make sense to construct the `BlockContents` which might be corrupted. In the stress test, we find that `assert(req.result.size() == block_size(handle));` fails because of potential IO errors.
In this PR, we explicitly free the scratch buffer on error without constructing `BlockContents`.

Also added fancy logic to format-diff.sh to make clang-format-diff.py for Python2 work even with Python3 only (as some CentOS 8 FB machines come equipped)
Also, now use just 'python3' for PYTHON if not found so that an informative
"command not found" error will result rather than something weird.

Summary:
`IterKey::UpdateInternalKey()` is an error-prone API as it's
incompatible with `IterKey::TrimAppend()`, which is used for
decoding delta-encoded internal keys. This PR stops using it in
`BlockIter`. Instead, it assigns global seqno in a separate `IterKey`'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.

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.

Summary:
This patch is groundwork for an upcoming change to store the set of
linked SSTs in `BlobFileMetaData`. With the current code, a new
`BlobFileMetaData` object is created each time a `VersionEdit` touches
a certain blob file. This is fine as long as these objects are lightweight
and cheap to create; however, with the addition of the linked SST set, it would
be very inefficient since the set would have to be copied over and over again.
Note that this is the same kind of problem that `VersionBuilder` is solving
w/r/t `Version`s and files, and we can apply the same solution; that is, we can
accumulate the changes in a different mutable object, and apply the delta in
one shot when the changes are committed. The patch does exactly that by
adding a new `BlobFileMetaDataDelta` class to `VersionBuilder`. In addition,
it turns the existing `GetBlobFileMetaData` helper into `IsBlobFileInVersion`
(which is fine since that's the only thing the method's clients care about now),
and adds a couple of helper methods that can create a `BlobFileMetaData`
object from the `BlobFileMetaData` in the base (if applicable) and the delta
when the `Version` is saved.

Since direct IO is supported in `RandomAccessFileReader::MultiRead` in https://github.com/facebook/rocksdb/pull/6446, this PR applies `MultiRead` to `MultiGet` so that the data blocks can be retrieved in parallel.
Also, in direct IO mode and when data blocks are compressed and need to uncompressed, this PR only allocates one continuous aligned buffer to hold the data blocks, and then directly uncompress the blocks to insert into block cache, there is no longer intermediate copies to scratch buffers.

Summary:
Currently when building PyTorch with latest RocksDB we get errors like "missing target Snappy::snappy", because they are simply not there.
With old `${VAR}` approach we essentially hard-code the abs path found during RocksDB build, which is:
- Not relocatable.
- Doesn't work when changed to modern target-based design because that requires target to present when used for expansion.
This fix allows cmake to setup imported target, if enabled during RocksDB build, when downstream uses `find_package(RocksDB)`.

Summary:
sst_dump can issue many file reads from the file system. This doesn't work well with file systems without a OS cache, especially remote file systems. In order to mitigate this problem, several improvements are done:
1. --readahead_size is added, so that users can specify readahead size when scanning the data.
2. Force a 512KB tail readahead, which prevents three I/Os for footer, meta index and property blocks and hopefully index and filter blocks too.
3. Consoldiate SSTDump's I/Os before opening the file for read. Use the same file prefetch buffer.

Summary:
Disable `TimerTest.SingleScheduleRepeatedlyTest` and `TimerTest.MultipleScheduleRepeatedlyTest`. This is to help people to not hit any hangs (https://github.com/facebook/rocksdb/issues/6698) during their development process while I investigate further; I could not reproduce the issue on my dev machine yet. Note that timer is not being utilized anywhere yet.

Summary:
When using ldb, users cannot turn on force consistency check in most commands, while they cannot use checksonsistnecy with --try_load_options. The change fixes both by:
1. checkconsistency now calls OpenDB() so that it gets all the options loading and sanitized options logic
2. use options.check_consistency_checks = true by default, and add a --disable_consistency_checks to turn it off.

Test Plan: Add a new unit test. Some manual tests with corrupted DBs.

Summary:
UBSAN shows following warning:

Suppress it just as what we do in x86 CRC.

Test Plan: Run the same UBSAN and see it to pass now.
