Summary: There are a few options in struct DBOptions that aren't handled by options_helper.cc. Add those missing options so they can be used by GetDBOptionsFromString() and friends.
Test Plan: Updated options_test.cc, reran all tests.

Summary:
This patch fix a race condition in persisting options which will cause a crash when:
* Thread A obtain cf options and start to persist options based on that cf options.
* Thread B kicks in and finish DropColumnFamily and delete cf_handle.
* Thread A wakes up and tries to finish the persisting options and crashes.
Test Plan: Add a test in column_family_test that can reproduce the crash

Summary:
Introduce TableOptions section and support BlockBasedTable in RocksDB
options file. A TableOptions section has the following format:
[TableOptions/<FactoryClassName> "<ColumnFamily Name>"]
which includes information about its TableFactory class and belonging
column family. Below is an example TableOptions section of a
BlockBasedTableOptions that belongs to the default column family:
[TableOptions/BlockBasedTable "default"]
format_version=0
whole_key_filtering=true
block_size_deviation=10
block_size=4096
block_restart_interval=16
filter_policy=nullptr
no_block_cache=false
checksum=kCRC32c
cache_index_and_filter_blocks=false
index_type=kBinarySearch
hash_index_allow_collision=true
flush_block_policy_factory=FlushBlockBySizePolicyFactory
Currently, Cache-type options (i.e., block_cache and block_cache_compressed)
are not supported.

Summary:
RocksDBOptionsParser now supports CompressionType and the following
pointer-typed options in RocksDBOptionParser
for sanity check:
prefix_extractor
table_factory
comparator
compaction_filter
compaction_filter_factory
merge_operator
memtable_factory
In the RocksDB Options file, only high level information about pointer-typed
options are serialized, and those information is only used for verification
/ sanity check purpose.
Test Plan: added more tests in options_test

Summary:
Previously, we treat deprecated options as normal options in
RocksDBOptionsParser. However, these deprecated options should
not be verified and serialized.

Summary:
This patch defines the format of RocksDB options file, which
follows the INI file format, and implements functions for its
serialization and deserialization. An example RocksDB options
file can be found in examples/rocksdb_option_file_example.ini.
A typical RocksDB options file has three sections, which are
Version, DBOptions, and more than one CFOptions. The RocksDB
options file in general follows the basic INI file format
with the following extensions / modifications:
* Escaped characters
We escaped the following characters:
- \n -- line feed - new line
- \r -- carriage return
- \\ -- backslash \
- \: -- colon symbol :
- \# -- hash tag #
* Comments
We support # style comments. Comments can appear at the ending
part of a line.
* Statements
A statement is of the form option_name = value.
Each statement contains a '=', where extra white-spaces
are supported. However, we don't support multi-lined statement.
Furthermore, each line can only contain at most one statement.
* Section
Sections are of the form [SecitonTitle "SectionArgument"],
where section argument is optional.
* List
We use colon-separated string to represent a list.
For instance, n1:n2:n3:n4 is a list containing four values.
Below is an example of a RocksDB options file:
[Version]
rocksdb_version=4.0.0
options_file_version=1.0
[DBOptions]
max_open_files=12345
max_background_flushes=301
[CFOptions "default"]
[CFOptions "the second column family"]
[CFOptions "the third column family"]
Test Plan: Added many tests in options_test.cc
