Summary: Dhruba can't compile on gcc4.8.1 so I'm moving temporarily back to 4.7.1 until we figure out what's wrong with 4.8. on his server.
Test Plan: It can compile on my devserver, but please 'arc patch' this diff and try compiling on your machine

Argumentation here: https://github.com/facebook/rocksdb/issues/9
Even though we include snappy in the distribution, we do not link with it if we don't have snappy installed on the system.
Installing snappy is easy nowadays, just type:
sudo apt-get install libsnappy-dev
Test Plan: compile on ubuntu

Finally did it - the trick was in using --dynamic-linker option. This is first step to running ASAN.
All of our code seems to compile just fine on 4.8.1. However, I still left fbcode.471.sh in the 'build_tools/' just in case.
Test Plan: make clean; make

Summary: Converted db_stress, db_repl_stress and db_bench to use gflags
Test Plan: I tested by printing out all the flags from old and new versions. Tried defaults, + various combinations with "interesting flags". Also, tested by running db_crashtest.py and db_crashtest2.py.

Summary:
Create a new type of file on startup if it doesn't already exist called DBID.
This will store a unique number generated from boost library's uuid header file.
The use-case is to identify the case of a db losing all its data and coming back up either empty or from an image(backup/live replica's recovery)
the key point to note is that DBID is not stored in a backup or db snapshot
It's preferable to use Boost for uuid because:
1) A non-standard way of generating uuid is not good
2) /proc/sys/kernel/random/uuid generates a uuid but only on linux environments and the solution would not be clean
3) c++ doesn't have any direct way to get a uuid
4) Boost is a very good library that was already having linkage in rocksdb from third-party
Note: I had to update the TOOLCHAIN_REV in build files to get latest verison of boost from third-party as the older version had a bug.
I had to put Wno-uninitialized in Makefile because boost-1.51 has an unitialized variable and rocksdb would not comiple otherwise. Latet open-source for boost is 1.54 but is not there in third-party. I have notified the concerned people in fbcode about it.
@kailiu : While releasing to third-party, an additional dependency will need to be created for boost in TARGETS file. I can help identify.
Test Plan:
Expand db_test to test 2 cases
1) Restarting db with Id file present - verify that no change to Id
2)Restarting db with Id file deleted - verify that a different Id is there after reopen
Also run make all check

Summary:
the valgrind version being used is in facebook specific path and should be moved to the fbcode.gcc471.sh file instead of the makefile.
The execution takes the environment's default valgrind version if the fbcode.gcc471.sh's valgrind_version is not available.

Summary:
clang is an alternate compiler based on llvm. It produces
nicer error messages and finds some bugs that gcc doesn't, such as the
size_t change in this file (which caused some write return values to be
misinterpreted!)
Clang isn't the default; to try it, do "USE_CLANG=1 make" or "export
USE_CLANG=1" then make as normal
Test Plan: "make check" and "USE_CLANG=1 make check"

Summary:
Specific changes:
1) Turn on -Werror so all warnings are errors
2) Fix some warnings the above now complains about
3) Add proper dependency support so changing a .h file forces a .c file
to rebuild
4) Automatically use fbcode gcc on any internal machine rather than
whatever system compiler is laying around
5) Fix jemalloc to once again be used in the builds (seemed like it
wasn't being?)
6) Fix issue where 'git' would fail in build_detect_version because of
LD_LIBRARY_PATH being set in the third-party build system
Test Plan:
make, make check, make clean, touch a header file, make sure
rebuild is expected

This patch keeps the same behaviour but allows the compilation
process to switch off msse if needed.

make clean all
