6a82fba75f Add missing hashCode() implementation
Summary:
Whenever a Java class implements equals(), it has to implement hashCode(), otherwise
there might be weird behavior when inserting instances of the class in a hash map for
example. This adds two missing hashCode() implementations and extends tests to test
the hashCode() implementations.

6002801e09 Abandon ROCKSDB_WARNING
Summary:
My latest fix to pragma_error.h caused compilation errors for another internal project.  I am now unable to figure out how to get pragma_error working on all platforms and build environments (nor am I able to test any other options).

Seems like the best option is to get rid of this macro.  include/utilities has been deprecated for a year now, so lets just deal with a breaking change in 3.13 to remove these files.  And I guess we'll have to live with having an extra convenience.h.

Thoughts?

fe09a6dae3 [wal changes 2/3] write with sync=true syncs previous unsynced wals to prevent illegal data loss
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

3dbf4ba220 RangeSync not to sync last 1MB of the file
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)."

35ca59364c Don't let flushes preempt compactions
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)

79373c372d Fix ROCKSDB_WARNING
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?

a96fcd09b7 Deprecate CompactionFilterV2
Summary: It has been around for a while and it looks like it never found any uses in the wild. It's also complicating our compaction_job code quite a bit. We're deprecating it in 3.13, but will put it back in 3.14 if we actually find users that need this feature.

Test Plan: make check

1d20fa9d0f Fixed and simplified merge_helper
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.

Test Plan: make && make check
