Summary:
Current flush reason attribution is misleading or incorrect (depending on what the original intention was):
- Flush due to WAL reaching its maximum size is attributed to `kWriteBufferManager`
- Flushes due to full write buffer and write buffer manager are not distinguishable, both are attributed to `kWriteBufferFull`
This changes the first to a new flush reason `kWALFull`, and splits the second between `kWriteBufferManager` and `kWriteBufferFull`.

Summary:
Forgot to re-test crash test after adding read-only filesystem
enforcement to https://github.com/facebook/rocksdb/issues/8142. The problem is ReadOnlyFileSystem would reject
CreateDirIfMissing whenever DBOptions::create_if_missing=true. The fix
that is better for users is to allow CreateDirIfMissing in
ReadOnlyFileSystem if the directory exists, so that they don't cause a
failure on using create_if_missing with opening backups as read-only
DBs. Added this option test to the unit test (in addition to being in the
crash test).
Also fixed a couple of lints.
And some better messaging from 'make format' so that when you run it
with uncommitted changes, it's clear that it's only checking the
uncommitted changes.

Summary:
A current limitation of backups is that you don't know the
exact database state of when the backup was taken. With this new
feature, you can at least inspect the backup's DB state without
restoring it by opening it as a read-only DB.
Rather than add something like OpenAsReadOnlyDB to the BackupEngine API,
which would inhibit opening stackable DB implementations read-only
(if/when their APIs support it), we instead provide a DB name and Env
that can be used to open as a read-only DB.
Possible follow-up work:
* Add a version of GetBackupInfo for a single backup.
* Let CreateNewBackup return the BackupID of the newly-created backup.
Implementation details:
Refactored ChrootFileSystem to split off new base class RemapFileSystem,
which allows more general remapping of files. We use this base class to
implement BackupEngineImpl::RemapSharedFileSystem.
To minimize API impact, I decided to just add these fields `name_for_open`
and `env_for_open` to those set by GetBackupInfo when
include_file_details=true. Creating the RemapSharedFileSystem adds a bit
to the memory consumption, perhaps unnecessarily in some cases, but this
has been mitigated by (a) only initialize the RemapSharedFileSystem
lazily when GetBackupInfo with include_file_details=true is called, and
(b) using the existing `shared_ptr<FileInfo>` objects to hold most of the
mapping data.
To enhance API safety, RemapSharedFileSystem is wrapped by new
ReadOnlyFileSystem which rejects any attempts to write. This uncovered a
couple of places in which DB::OpenForReadOnly would write to the
filesystem, so I fixed these. Added a release note because this affects
logging.
Additional minor refactoring in backupable_db.cc to support the new
functionality.

Summary:
According to https://github.com/facebook/rocksdb/issues/5907, each filter partition "should include the bloom of the prefix of the last
key in the previous partition" so that SeekForPrev() in prefix mode can return correct result.
The prefix of the last key in the previous partition does not necessarily have the same prefix
as the first key in the current partition. Regardless of the first key in current partition, the
prefix of the last key in the previous partition should be added. The existing code, however,
does not follow this. Furthermore, there is another issue: when finishing current filter partition,
`FullFilterBlockBuilder::AddPrefix()` is called for the first key in next filter partition, which effectively
overwrites `last_prefix_str_` prematurely. Consequently, when the filter block builder proceeds
to the next partition, `last_prefix_str_` will be the prefix of its first key, leaving no way of adding
the bloom of the prefix of the last key of the previous partition.
Prefix extractor is FixedLength.2.
```
[ filter part 1 ] [ filter part 2 ]
abc d
```
When SeekForPrev("abcd"), checking the filter partition will land on filter part 2 because "abcd" > "abc"
but smaller than "d".
If the filter in filter part 2 happens to return false for the test for "ab", then SeekForPrev("abcd") will build
incorrect iterator tree in non-total-order mode.
Also fix a unit test which starts to fail following this PR. `InDomain` should not fail due to assertion
error when checking on an arbitrary key.

For the set of exclusions, I only listed things that currently failed
for me when attempting not to exclude, or had some other documented
reason. This marks many more tests as "parallel," which will potentially
cause some failures from self-interference, but we can address those as
they are discovered.
Also changed CircleCI ASC test to be parallelized; the easy way to do
that is to exclude building tests that don't pass ASC, which is now a
small set.

Summary:
At least under MacOS, some things were excluded from the build (like Snappy) because the compilation flags were not passed in correctly. This PR does a few things:
- Passes the EXTRA_CXX/LDFLAGS into build_detect_platform. This means that if some tool (like TBB for example) is not installed in a standard place, it could still be detected by build_detect_platform. In this case, the developer would invoke: "EXTRA_CXXFLAGS=<path to TBB include> EXTRA_LDFLAGS=<path to TBB library> make", and the build script would find the tools in the extra location.
- Changes the compilation tests to use PLATFORM_CXXFLAGS. This change causes the EXTRA_FLAGS passed in to the script to be included in the compilation check. Additionally, flags set by the script itself (like --std=c++11) will be used during the checks.
Validated that the make_platform.mk file generated on Linux does not change with this change. On my MacOS machine, the SNAPPY libraries are now available (they were not before as they required --std=c++11 to build).
I also verified that I can build against TBB installed on my Mac by passing in the EXTRA CXX and LD FLAGS to the location in which TBB is installed.

Summary:
In DBImpl::CloseHelper, we wait for bg_compaction_scheduled_
and bg_flush_scheduled_ to drop to 0. Unschedule is called prior
to cancel any unscheduled flushes/compactions. It is assumed that
anything in the high priority is a flush, and anything in the low
priority pool is a compaction. This assumption, however, is broken when
the high-pri pool is full.
As a result, bg_compaction_scheduled_ can go < 0 and bg_flush_scheduled_
will remain > 0 and DB can be in hang state.
The fix is, we decrement the `bg_{flush,compaction,bottom_compaction}_scheduled_`
inside the `Unschedule{Flush,Compaction,BottomCompaction}Callback()`s. DB
`mutex_` will make the counts atomic in `Unschedule`.

Summary:
BackupEngine previously had unclear but strict concurrency
requirements that the API user must follow for safe use. Now we make
that clear, by separating operations into "Read," "Append," and "Write"
operations, and specifying which combinations are safe across threads on
the same BackupEngine object (previously none; now all, using a
read-write lock), and which are safe across different BackupEngine
instances open on the same backup_dir.
The changes to backupable_db.h should be backward compatible. It is
mostly about eliminating copies of what should be the same function and
(unsurprisingly) useful documentation comments were often placed on
only one of the two copies. With the re-organization, we are also
grouping different categories of operations. In the future we might add
BackupEngineReadAppendOnly, but that didn't seem necessary.
To mark API Read operations 'const', I had to mark some implementation
functions 'const' and some fields mutable.
Functional changes:
* Added RWMutex locking around public API functions to implement thread
safety on a single object. To avoid future bugs, this is another
internal class layered on top (removing many "override" in
BackupEngineImpl). It would be possible to allow more concurrency
between operations, rather than mutual exclusion, but IMHO not worth the
work.
* Fixed a race between Open() (Initialize()) and CreateNewBackup() for
different objects on the same backup_dir, where Initialize() could
delete the temporary meta file created during CreateNewBackup().
(This was found by the new test.)
Also cleaned up a couple of "status checked" TODOs, and improved a
checksum mismatch error message to include involved files.
Potential follow-up work:
* CreateNewBackup has an API wart because it doesn't tell you the
BackupID it just created, which makes it of limited use in a multithreaded
setting.
* We could also consider a Refresh() function to catch up to
changes made from another BackupEngine object to the same dir.
* Use a lock file to prevent multiple writer BackupEngines, but this
won't work on remote filesystems not supporting lock files.

The reason why the file is created like so is because stdio streams opened with fopen calls use mode 0666, and while normally most systems have a umask of 022, in some occasions (for instance, while running daemons), you may find that the application is running with a less restrictive umask. The result is that when opening the DB, the LOG file would be created with world-writeable perms:
```
$ ls -lh db/
total 6.4M
-rw-r--r-- 1 ibarba users 115 Mar 24 17:41 000004.log
-rw-r--r-- 1 ibarba users 16 Mar 24 17:41 CURRENT
-rw-r--r-- 1 ibarba users 37 Mar 24 17:41 IDENTITY
-rw-r--r-- 1 ibarba users 0 Mar 24 17:41 LOCK
-rw-rw-r-- 1 ibarba users 114K Mar 24 17:41 LOG
-rw-r--r-- 1 ibarba users 514 Mar 24 17:41 MANIFEST-000003
-rw-r--r-- 1 ibarba users 31K Mar 24 17:41 OPTIONS-000018
-rw-r--r-- 1 ibarba users 31K Mar 24 17:41 OPTIONS-000020
```
This diff replaces the fopen call with a regular open() call restricting mode, and then using fdopen to associate an stdio stream with that file descriptor. Resulting in the following files being created:
```
-rw-r--r-- 1 ibarba users 58 Mar 24 18:16 000004.log
-rw-r--r-- 1 ibarba users 16 Mar 24 18:16 CURRENT
-rw-r--r-- 1 ibarba users 37 Mar 24 18:16 IDENTITY
-rw-r--r-- 1 ibarba users 0 Mar 24 18:16 LOCK
-rw-r--r-- 1 ibarba users 111K Mar 24 18:16 LOG
-rw-r--r-- 1 ibarba users 514 Mar 24 18:16 MANIFEST-000003
-rw-r--r-- 1 ibarba users 31K Mar 24 18:16 OPTIONS-000018
-rw-r--r-- 1 ibarba users 31K Mar 24 18:16 OPTIONS-000020
```

Summary:
The check in db_bench for table_cache_numshardbits was 0 < bits <= 20, whereas the check in LRUCache was 0 < bits < 20. Changed the two values to match to avoid a crash in db_bench on a null cache.

Summary:
Ran a spell check over the comments in the include/rocksdb directory and fixed any mis-spellings.
There are still some variable names that are spelled incorrectly (like SizeApproximationOptions::include_memtabtles, SstFileMetaData::oldest_ancester_time) that were not fixed, as those would break compilation.

Summary:
Because build_version.cc is dependent on the library objects (to force a re-generation of it), the library objects would be built in order to satisfy this rule. Because there is a build_version.d file, it would need generated and included.
Change the ALL_DEPS/FILES to not include build_version.cc (meaning no .d file for it, which is okay since it is generated). Also changed the rule on whether or not to generate DEP files to skip tags.

Summary:
Currently, we only truncate the latest alive WAL files when the DB is opened. If the latest WAL file is empty or was flushed during Open, its not truncated since the file will be deleted later on in the Open path. However, before deletion, a new WAL file is created, and if the process crash loops between the new WAL file creation and deletion of the old WAL file, the preallocated space will keep accumulating and eventually use up all disk space. To prevent this, always truncate the latest WAL file, even if its empty or the data was flushed.
Tests:
Add unit tests to db_wal_test
