Summary: These tests used to fail if a compaction happened between flushing tables and enumerating them to get properties.
Test Plan: this reports occasional failures without this diff and no failures with it: `for i in {1..10000}; do echo $i; done | parallel --gnu -j100 'TEST_TMPDIR=`TMPDIR=/dev/shm/rockstemp mktemp -d -t` ./db_test --gtest_filter=DBTest.GetUserDefinedTablaProperties >&/dev/null || echo {} failed'`

Summary:
I'll just copy internal task summary here:
"
This sequence will cause data loss in the middle after an sync write:
non-sync write key 1
flush triggered, not yet scheduled
sync write key 2
system crash
After rebooting, users might see key 2 but not key 1, which violates the API of sync write.
This can be reproduced using unit test FaultInjectionTest::DISABLED_WriteOptionSyncTest.
One way to fix it is for a sync write, if there is outstanding unsynced log files, we need to syc them too.
"
This diff should be considered together with the next diff D40905; in isolation this fix probably could be a little simpler.
Test Plan: `make check`; added a test for that (DBTest.SyncingPreviousLogs) before noticing FaultInjectionTest.WriteOptionSyncTest (keeping both since mine asserts a bit more); both tests fail without this diff; for D40905 stacked on top of this diff, ran tests with ASAN, TSAN and valgrind

Summary:
From other ones' investigation:
"sync_file_range() behavior highly depends on kernel version and filesystem.
xfs does neighbor page flushing outside of the specified ranges. For example, sync_file_range(fd, 8192, 16384) does not only trigger flushing page #3 to #4, but also flushing many more dirty pages (i.e. up to page#16)... Ranges of the sync_file_range() should be far enough from write() offset (at least 1MB)."

It will make it easier to maintain multiple Env in the future.

Summary:
When we first started, max_background_flushes was 0 by default and compaction thread was executing flushes (since there was no flush thread). Then, we switched the default max_background_flushes to 1. However, we still support the case where there is no flush thread and flushes are done in compaction. This is making our code a bit more complicated. By not supporting this use-case we can make our code simpler.
We have a special case that when you set max_background_flushes to 0, we
schedule the flush to execute on the compaction thread.
Test Plan: make check (there might be some unit tests that depend on this behavior)

Summary:
ROCKSDB_WARNING is only defined if either ROCKSDB_PLATFORM_POSIX or OS_WIN is defined. This works well for building rocksdb with its own build scripts. But this won't work when an outside project(like mongodb) doesn't define ROCKSDB_PLATFORM_POSIX.
This fix defines ROCKSDB_WARNING for all platforms. No idea if its defined correctly on non-posix,non-windows platforms but this is no worse that the current situation where this macro is missing on unexpected platforms.
This fix should hopefully fix anyone whose build broke now that we've switched from using #warning to Pragma (to support windows). Unfortunately, while mongo-rocks compiles, it ignores the Pragma and doesn't print a warning. I have not been able to figure out a way to implement this portably on all platforms.
Of course, an alternate solution would be to just get rid of ROCKSDB_WARNING and live with include file redirects indefinitely. Thoughts?

Summary:
MergeUntil was not reporting a success when merging an operand with
a Value/Deletion despite the comments in MergeHelper and CompactionJob
indicating otherwise. This lead to operands being written to the compaction
output unnecessarily:
M1 M2 M3 P M4 M5 --> (P+M1+M2+M3) M2 M3 M4 M5 (before the diff)
M1 M2 M3 P M4 M5 --> (P+M1+M2+M3) M4 M5 (after the diff)
In addition, the code handling Values/Deletion was basically identical.
This patch unifies the code. Finally, this patch also adds testing for
merge_helper.

- minor changes in CMakeLists to reflect recent changes
Summary:
Previous run may leave some SST files with higher file numbers than manifest indicates.
Compaction or flush may start to run while DB::Open() is still going on. SST file garbage collection may happen interleaving with compaction or flush, and overwrite files generated by compaction of flushes after they are generated. This might cause data loss. This possibility of interleaving is recently introduced.
Fix it by not allowing compaction or flush to be scheduled before DB::Open() finishes.
Test Plan: Add a unit test. This verification will have a chance to fail without the fix but doesn't fix without the fix.

Note: depending on the type of corruption and options like comparators,
CompactionJob fails. This test just checks whether corrupted keys that
do not fail CompactionJob are preserved.
Test Plan:
`make compaction_job_test && ./compaction_job_test` -> Tests pass.
Add `input->Next(); continue;` in CompactionJob::ProcessKeyValueCompaction()
inside then-branch of `!ParseInternalKey(key, &ikey)` -> Tests fail.
