Summary:
During recovery, multiple (un)prepared batches could exist in the same WAL record due to group commit. This breaks an assertion in `MemTableInserter::MarkBeginPrepare`.
To fix, reset unprepared_batch_ to false after `MarkEndPrepare`.

Summary:
Unfortunately, it seems like mysqld reuses xids across machine restarts. When that happens, we could have something like the following happening:
```
BEGIN_PREPARE(unprepared) Put(a) END_PREPARE(xid = 1)
-- crash and recover with Put(a) rolled back as it was not prepared
BEGIN_PREPARE(prepared) Put(b) END_PREPARE(xid = 1)
COMMIT(xid = 1)
-- crash and recover with both a, b
```
To solve this, we will have to log the rollback batch into the WAL during recovery.
WritePrepared already logs the rollback batch into the WAL, if a rollback happens after prepare, so there is no problem there.

Summary:
The DecreaseNumBgThreads test keeps failing on Windows in AppVeyor.
It fails because it depends on a timed wait for the tasks to be dequeued from the threadpool's internal queue, but within the specified time, the task might have not been scheduled onto the newly created threads.
https://github.com/facebook/rocksdb/pull/6232 tries to fix this by waiting for longer time to let the threads scheduled.
This PR tries to fix this by replacing the timed wait with a synchronization on the task's internal conditional variable.
When the number of threads increases, instead of guessing the time needed for the task to be scheduled, it directly blocks on the conditional variable until the task starts running.
But when thread number is reduced, it still does a timed wait, but this does not lead to the flakiness now, will try to remove these timed waits in a future PR.

`AddEdit` moves the `VersionEdit` passed to it into `replay_buffer_`,
however, the client `VersionSet` classes keep using it afterwards. This
*seemed to* work before the refactoring but it really did not: since
`VersionEdit` used to have a user-declared destructor, no move
constructor/move assignment operator was generated, and the `move` in
`AddEdit` was really a copy. The patch makes the copy explicit. Note: it
should be possible to rework this logic so that we can get away
with the move but for now, this should fix the issue.

After a SST file is generated by Flush or Compaction, RocksDB generate the SST file checksum and store the checksum value and checksum method name in the vs_info and MANIFEST as part for the FileMetadata.
Added the enable_sst_file_checksum to Options to enable or disable file checksum. Added sst_file_checksum to Options such that user can plugin their own SST file checksum calculate method via overriding the SstFileChecksum class. The checksum information inlcuding uint32_t checksum value and a checksum name (string). A new tool is added to LDB such that user can dump out a list of file checksum information from MANIFEST. If user enables the file checksum but does not provide the sst_file_checksum instance, RocksDB will use the default crc32checksum implemented in table/sst_file_checksum_crc32c.h

* Makes the names and order of variables, methods, and code chunks related
to the various information elements more consistent, and adds missing
getters for the sake of completeness.
* Initializes previously uninitialized stack variables.
* Marks all getters const to improve const correctness.
* Adds in-class initializers and removes the default ctor that would
create an object with uninitialized built-in fields and call `Clear`
afterwards.
* Adds a new type alias for new files and changes the existing `typedef`
for deleted files into a type alias as well.
* Makes the helper method `DecodeNewFile4From` private.
* Switches from long-winded iterator syntax to range based loops in a
couple of places.
* Fixes a couple of assignments where an integer 0 was assigned to
boolean members.
* Fixes a getter which used to return a `const std::string` instead of
the intended `const std::string&`.

Summary:
BlobDB keeps track of the mapping between SSTs and blob files using
the `OnFlushCompleted` and `OnCompactionCompleted` callbacks of
the `EventListener` interface: upon receiving a flush notification, a link
is added between the newly flushed SST and the corresponding blob file;
for compactions, links are removed for the inputs and added for the outputs.
The earlier code performed this link deletion and addition even for
trivially moved files; the new code walks through the two lists together
(in a fashion that's similar to merge sort) and skips such files.
This should mitigate https://github.com/facebook/rocksdb/issues/6338,
wherein an assertion is triggered with the earlier code when a compaction
notification for a trivial move precedes the flush notification for the
moved SST.

In `DBSSTTest.SSTsWithLdbSuffixHandling`, some sst files are renamed to ldb files, the original intention of the test is to test that the ldb files can be loaded along with the sst files.
The original test checks this by `ASSERT_NE("NOT_FOUND", Get(Key(k)))`, but the problem is `Get(Key(k))` returns IO error due to path not found instead of NOT_FOUND, so the success of ASSERT_NE does not mean the key can be retrieved.

Before this PR it calls GetFileSize() once for each sst file in the DB. This can take a long time if there are be tens of thousands of sst files (e.g. in thousands of column families), and even longer if Env is talking to some remote service rather than local filesystem. This PR makes DB::Open() use sst file sizes that are already known from manifest (typically almost all files in the DB) and only call GetFileSize() for non-sst or obsolete files. Note that GetFileSize() is also called and checked against manifest in CheckConsistency(), so the calls in SstFileManagerImpl were completely redundant.

Summary:
When paranoid_checks is on, DBImpl::CheckConsistency() iterates over all sst files and calls Env::GetFileSize() for each of them. As far as I could understand, this is pretty arbitrary and doesn't affect correctness - if filesystem doesn't corrupt fsynced files, the file sizes will always match; if it does, it may as well corrupt contents as well as sizes, and rocksdb doesn't check contents on open.
If there are thousands of sst files, getting all their sizes takes a while. If, on top of that, Env is overridden to use some remote storage instead of local filesystem, it can be *really* slow and overload the remote storage service. This PR adds an option to not do GetFileSize(); instead it does GetChildren() for parent directory to check that all the expected sst files are at least present, but doesn't check their sizes.
We can't just disable paranoid_checks instead because paranoid_checks do a few other important things: make the DB read-only on write errors, print error messages on read errors, etc.

Summary:
This is a redesign of the API for RocksJava comparators with the aim of improving performance. It also simplifies the class hierarchy.
**NOTE**: This breaks backwards compatibility for existing 3rd party Comparators implemented in Java... so we need to consider carefully which release branches this goes into.
Previously when implementing a comparator in Java the developer had a choice of subclassing either `DirectComparator` or `Comparator` which would use direct and non-direct byte-buffers resepectively (via `DirectSlice` and `Slice`).
In this redesign there we have eliminated the overhead of using the Java Slice classes, and just use `ByteBuffer`s. The `ComparatorOptions` supplied when constructing a Comparator allow you to choose between direct and non-direct byte buffers by setting `useDirect`.
In addition, the `ComparatorOptions` now allow you to choose whether a ByteBuffer is reused over multiple comparator calls, by setting `maxReusedBufferSize > 0`. When buffers are reused, ComparatorOptions provides a choice of mutex type by setting `useAdaptiveMutex`.
---
[JMH benchmarks previously indicated](https://github.com/facebook/rocksdb/pull/6241#issue-356398306) that the difference between C++ and Java for implementing a comparator was ~7x slowdown in Java.
With these changes, when reusing buffers and guarding access to them via mutexes the slowdown is approximately the same. However, these changes offer a new facility to not reuse mutextes, which reduces the slowdown to ~5.5x in Java. We also offer a `thread_local` mechanism for reusing buffers, which reduces slowdown to ~5.2x in Java (closes https://github.com/facebook/rocksdb/pull/4425).
These changes also form a good base for further optimisation work such as further JNI lookup caching, and JNI critical.

These numbers were captured without jemalloc. With jemalloc, the performance improves for all tests, and the Java slowdown reduces to between 4.8x and 5.x.

Pull Request resolved: https://github.com/facebook/rocksdb/pull/6252
Differential Revision: D19331064

fbshipit-source-id: 1f3b794e6a14162b2c3ffb943e8c0e64a0c03738
Summary:
DBTest2.ChangePrefixExtractor fails in LITE build because LITE build doesn't support adaptive build. Fix it by removing the stats check but only check correctness.
Pull Request resolved: https://github.com/facebook/rocksdb/pull/6356
Test Plan: Run the test with both of LITE and non-LITE build.
Differential Revision: D19669537
fbshipit-source-id: 6d7dd6c8a79f18e80ca1636864b9c71922030d8e
Summary:
Add a unit test for prefix extractor change, including a check that fails due to a bug.
Also comment out the partitioned filter case which will fail the test too.
Pull Request resolved: https://github.com/facebook/rocksdb/pull/6323
Test Plan: Run the test and it passes (and fails if the SeekForPrev() part is uncommented)

Summary:
Background jobs in WritePrepared DB might access the db via a snapshot checker callback. The stress tests therefore should cancel background jobs before deleting the db in ::Reopen.
