Summary:
InlineSkipList::InsertConcurrently should invalidate the
sequential-insertion cache prev_[] for all inserts of multi-level nodes,
not just those that increase the height of the skip list. The invariant
for prev_ is that prev_[i] (i > 0) is supposed to be the predecessor of
prev_[0] at level i. Before this diff InsertConcurrently could violate
this constraint when inserting a multi-level node after prev_[i] but
before prev_[0].
This diff also reenables kConcurrentSkipList as db_test's
MultiThreaded/MultiThreadedDBTest.MultiThreaded/29.
Test Plan:
1. unit tests
2. temporarily hack kConcurrentSkipList timing so that it is fast but has a 1.5% failure rate on my dev box (1ms stagger on thread launch, 1s test duration, failure rate baseline over 1000 runs)
3. observe 1000 passes post-fix

Summary:
Some of the tests aren't considered to be critical when it comes to getting key benchmarking data for RocksDB. Therefore we'll introduce an environment variable `SKIP_LOW_PRI_TESTS` which enables skipping those test cases. By default all the tests will be run. If you want to optimize the test-case execution then do the following:
`
$ export SKIP_LOW_PRI_TESTS=1
$ ./tools/run_flash_bench.sh
`
Test Plan: Verified that when `SKIP_LOW_PRI_TESTS` is not set then `benchmark.sh` is called for all the scenarios and when `SKIP_LOW_PRI_TESTS` is set to `1` then `benchmark.sh` is called only for the test-cases which are critical.

Summary:
Before this diff, there were duplicated constants to refer to properties (user-
facing API had strings and InternalStats had an enum). I noticed these were
inconsistent in terms of which constants are provided, names of constants, and
documentation of constants. Overall it seemed annoying/error-prone to maintain
these duplicated constants.
So, this diff gets rid of InternalStats's constants and replaces them with a map
keyed on the user-facing constant. The value in that map contains a function
pointer to get the property value, so we don't need to do string matching while
holding db->mutex_. This approach has a side benefit of making many small
handler functions rather than a giant switch-statement.
Test Plan: db_properties_test passes, running "make commit-prereq -j32"

Summary:
Following up on D53493, we can still enable the filter-skipping
optimization for last file in L0. It's correct to assume the key will be present
in the last L0 file when we're hit-optimized and L0 is deepest.
The FilePicker encapsulates the state for traversing each level's files, so I
needed to make it expose whether the returned file is last in its level.
Test Plan:
verified below test fails before this patch and passes afterwards.
The change to how the test memtable is populated is needed so file 1 has keys
(0, 30, 60), file 2 has keys (10, 40, 70), etc.

This change impacts only non-buffered I/O on Windows.
Currently, there is a buffer per RandomAccessFile
instance that is protected by a lock. The reason we
maintain the buffer is non-buffered I/O requires an aligned
buffer to work.
XPerf traces demonstrate that we accumulate a considerable
wait time while waiting for that lock.
This change enables to set random access buffer size to zero
which would indicate a per request allocation.
We are expecting that allocation expense would be much less than
I/O costs plus wait time due to the fact that the memory heap
would tend to re-use page aligned allocations especially with the
use of Jemalloc.
This change does not affect buffer use as a read_ahead_buffer for
compaction purposes.

Summary: It's a regression bug caused by e089db40f9. With the change, if options.optimize_filters_for_hits=true and there are only L0 files (like single level universal compaction), we skip all the files in L0, which is more than necessary. Fix it by always trying to query bloom filter for files in level 0.

Summary:
We can avoid the dependency by forward-declaring ColumnFamilyData and
then treating it as a black box. That means callers of ThreadStatusUtil need to
explicitly provide more options, even if they can be derived from the
ColumnFamilyData, since ThreadStatusUtil doesn't include the definition.
This is part of a series of diffs to eliminate circular dependencies between
directories (e.g., db/* files depending on util/* files and vice-versa).
