Previously, we treat deprecated options as normal options in

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

Add an optimized build config switch for faster test runs

Make appveyor build to utilize all the avaiable cores on the VM (parallel)
Introduce new appveyor configuration for daily test runs as it would take too long

Summary:
CompactionJobStatsTest.UniversalCompactionTest assumes compaction
kicks in when the number of L0 files equals to the compaction trigger.
However, in some case, the compaction might not catch up the write
speed and thus compaction might not kick in until the number of L0 files
is GREATER than the compaction trigger.
This patch tries to fix this corner case by making the Put thread wait
for a potential compaction whenever it flushes.

The previous memory allocation procedures tried to allocate memory
via `new` or `mmap` and inserted the pointer to the memory into an
std::vector afterwards. In case `new` or `mmap` threw or returned
a nullptr, no memory was leaking. If `new` or `mmap` worked ok, the
following `vector::push_back` could still fail and throw an exception.
In this case, the memory just allocated was leaked.
The fix is to reserve space in the target memory pointer block
beforehand. If this throws, then no memory is allocated nor leaked.
If the reserve works but the actual allocation fails, still no
memory is leaked, only the target vector will have space for at
least one more element than actually required (but this may be
reused for the next allocation)

PlainTableReader now only allows mmap-mode. Add the support to non-mmap mode for more flexibility.
Refactor the codes to move all logic of reading data to PlainTableKeyDecoder, and consolidate the calls to Read() call and ReadVarint32() call. Implement the calls for both of mmap and non-mmap case seperately. For non-mmap mode, make copy of keys in several places when we need to move the buffer after reading the keys.
Test Plan: Add the mode of non-mmap case in plain_table_db_test. Run it in valgrind mode too.
