7a23e4d8ca New amalgamation target
This commit adds two new targets to the Makefile: rocksdb.cc and rocksdb.h

These files, when combined with the c.h header, are a self-contained RocksDB
source distribution called an amalgamation. (The name comes from SQLite's, which
is similar in concept.)

The main benefit of an amalgamation is that it's very easy to drop into a
new project. It also compiles faster compared to compiling individual source
files and potentially gives the compiler more opportunity to make optimizations
since it can see all functions at once.

rocksdb.cc and rocksdb.h are generated by a new script, amalgamate.py.
A detailed description of how amalgamate.py works is in a comment at the top of
the file.

There are also some small changes to existing files to enable the amalgamation:
* Use quotes for includes in unity build
* Fix an old header inclusion in util/xfunc.cc
* Move some includes outside ifdef in util/env_hdfs.cc
* Separate out tool sources in Makefile so they won't be included in unity.cc
* Unity build now produces a static library

Closes #733

03b08ba9a9 Return MergeInProgress when fetching from transactions or WBWI with overwrite_key
Summary:
WriteBatchWithIndex::GetFromBatchAndDB only works correctly for overwrite_key=false.  Transactions use overwrite_key=true (since WriteBatchWithIndex::GetIteratorWithBase only works when overwrite_key=true).  So currently, Transactions could return incorrectly merged results when calling Get/GetForUpdate().

Until a permanent fix can be put in place, Transaction::Get[ForUpdate] and WriteBatchWithIndex::GetFromBatch[AndDB] will now return MergeInProgress if the most recent write to a key in the batch is a Merge.

74b100ac17 RocksDB Options file format and its serialization / deserialization.
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

30f74fa964 Make CompactionJobStatsTest.UniversalCompactionTest more robust
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.

aa58958d38 prevent potential memleaks in Arena::Allocate*()
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)

Summary:
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.
