5aca977be8 env_basic_test library for testing new Envs [pluggable Env part 3]
Summary:
- Provide env_test as a static library. We will build it for future releases so internal Envs can use env_test by linking against this library.
- Add tests for CustomEnv, which is configurable via ENV_TEST_URI environment variable. It uses the URI-based Env lookup (depends on D58449).
- Refactor env_basic_test cases to use a unique/configurable directory for test files.

Test Plan:
built a test binary against librocksdb_env_test.a. It registered the
default Env with URI prefix "a://".

- verify runs all CustomEnv tests when URI with correct prefix is provided

```
$ ENV_TEST_URI="a://ok" ./tmp --gtest_filter="CustomEnv/*"
...
[  PASSED  ] 12 tests.
```

- verify runs no CustomEnv tests when URI with non-matching prefix is provided

```
$ ENV_TEST_URI="b://ok" ./tmp --gtest_filter="CustomEnv/*"
...
[  PASSED  ] 0 tests.
```

1147e5b05a Adding support for sharing throttler between multiple backup and restores
Summary:
Rocksdb backup and restore rate limiting is currently done per backup/restore.
So, it is difficult to control rate across multiple backup/restores. With this
change, a throttler can be provided. If a throttler is provided, it is used.
Otherwise, a new throttler is created based on the actual rate limits specified
in the options.

Test Plan: Added unit tests

6e6622abb9 Create env_basic_test [pluggable Env part 2]
Summary:
Extracted basic Env-related tests from mock_env_test and memenv_test into a
parameterized test for Envs: env_basic_test.

Depends on D58449. (The dependency is here only so I can keep this series of
diffs in a chain -- there is no dependency on that diff's code.)

e532877940 Add statistics field to show total size of index and filter blocks in block cache
Summary: With `table_options.cache_index_and_filter_blocks = true`, index and filter blocks are stored in block cache. Then people are curious how much of the block cache total size is used by indexes and bloom filters. It will be nice we have a way to report that. It can help people tune performance and plan for optimized hardware setting. We add several enum values for db Statistics. BLOCK_CACHE_INDEX/FILTER_BYTES_INSERT - BLOCK_CACHE_INDEX/FILTER_BYTES_ERASE = current INDEX/FILTER total block size in bytes.

Test Plan:
write a test case called `DBBlockCacheTest.IndexAndFilterBlocksStats`. The result is:
```
[gzh@dev9927.prn1 ~/local/rocksdb]  make db_block_cache_test -j64 && ./db_block_cache_test --gtest_filter=DBBlockCacheTest.IndexAndFilterBlocksStats

af0c9ac01d Env registry for URI-based Env selection [pluggable Env part 1]
Summary:
This enables configurable Envs without recompiling. For example, my
next diff will make env_test test an Env created by NewEnvFromUri(). Then,
users can determine which Env is tested simply by providing the URI for
NewEnvFromUri() (e.g., through a CLI argument or environment variable).

The registration process allows us to register any Env that is linked with the
RocksDB library, so we can register our internal Envs as well.

The registration code is inspired by our internal InitRegistry.

Test Plan: new unit test

* kills all db_bench related processes before running db_bench
* better error handling.

Test Plan:
1. Run regression_test.sh both locally and remotely
2. Run multiple regression_test.sh at the same time and make sure
   i. Only one runs successfully.
   ii. The one that runs successfully will kill all other db_bench

Also add option `-simcache_size` in db_bench. if set with a value other than -1, then the benchmark will use this value as the size of the simulator cache and finally output the simulation result.

f89caa127b Direct IO capability for RocksDB
Summary:
This patch adds direct IO capability to RocksDB Env.

The direct IO capability is required for persistent cache since NVM is best
accessed as 4K direct IO. SSDs can leverage direct IO for reading.

Direct IO requires the offset and size be sector size aligned, and memory to
be kernel page aligned. Since neither RocksDB/Persistent read cache data
layout is aligned to sector size, the code can accommodate reading unaligned IO size
(or unaligned memory) at the cost of an alloc/copy.

The write code path expects the size and memory to be aligned.

Test Plan: Run RocksDB unit tests

11f329bd40 db/db_impl: restrict WALRecoveryMode when using recycled log files
kPointInTimeRecovery is indistinguishable from
kTolerateCorruptedTailRecords in recycle mode since we define
the "end" of the log as the first corrupt record we encounter.

kAbsoluteConsistency doesn't make sense because even a clean
shutdown leaves old junk at the end of the log file.

34df1c94d5 db/log_reader: treat bad record length or checksum as EOF
If we are in kTolerateCorruptedTailRecords, treat these
errors as the end of the log.  This is particularly
important for recycled logs, where we will regularly see
corrupted headers (bad length or checksum) when replaying
a log.  If we are aligned with a block boundary or get lucky,
we will land on an old header and see the log number
mismatch, but more commonly we will land midway through
some previous block and record and effectively see noise.
These must be treated as the end of the log in order for
recycling to work.

This makes the LogTest.Recycle/1 test pass.

We also modify a number of existing tests because the
recycled log files behave fundamentally differently in that
they always stop when they reach the first bad record.

The behavior here needs to depend on the WAL recovery mode.  No functional
change in this patch.

This currently fails because we do not properly map a
