Bazel build

[teodor-pripoae]

Hi,

I've added Bazel config files to allow reproductible builds. I tested them on OS X and Linux (Ubuntu).

When building using Bazel, it will download all required dependencies and will compile static binaries for host platform.

To build sofa-pbrpc-client, run:

$ bazel build sofa-pbrpc-client

To build examples:

$ bazel build sample/compress_sample:server
$ bazel build sample/compress_sample:client

$ bazel-bin/sample/compress_sample/server
$ bazel-bin/sample/compress_sample/client

Thanks for your pr, very convenience.

I'm still having a small problem with boost libs, it seems I can't include them as header only libs, I need to compile them into a static .a. I will fix it later today.

[teodor-pripoae]

Fixed compiling boost files.

@teodor-pripoae Thanks very much for your code ! I build successfully on Ubuntu12.04, but failed on centos7.3

Thanks :)

Can you send me the full output of bazel build please ?

I succesfully built it on centos 7.3 inside docker, using the following Dockerfile for bazel:

FROM centos:7.3.1611

# Build tools
RUN yum install gcc gcc-c++ kernel-devel wget unzip zlib-devel zip \
    git automake cmake patch libtool which glibc-static libstdc++-static \
    java-1.8.0-openjdk-devel

# Bazel
RUN wget -O /tmp/bazel.sh https://github.com/bazelbuild/bazel/releases/download/0.4.2/bazel-0.4.2-installer-linux-x86_64.sh && \
    chmod +x /tmp/bazel.sh && \
    /tmp/bazel.sh

@teodor-pripoae I found it's something wrong with my build environment and I succesfully built now. Thanks.
I find there's no bazel BUILD file in unit-test and test, would you mind adding these in this pr? :)

[teodor-pripoae]

I've added build file for unit-test, for test I will try in the following days. I tried using cc_test macros from bazel but there is an issue with protobuf beeing registered multiple times, so I've made a script to build and run the tests.

I will try to find a solution later this week.
