Translate synergistically embedded android

##描述:

• 大家业余时间充分利用起来，练练英语，学学android 翻译可以增加备注，增加自己查找的资料的链接，自己的认识，注意和正文做区分，自己结合工作认为比较重要的可以突出显示
  协同分工：
  史思远：我选第１章了，大家别跟我抢啊。。
  王新锋：第二章，我先翻译着，比较晦涩～
  郭鹏宇：第4章：编译系统

##github help

1. 进入项目地址，先fork这个项目到你的项目中
2. 把你fork的项目clone到你本地
3. git branch dev 新建一个分支
4. git checkout dev 切换到dev分支
5. git remote add upstream https://github.com/android0/embedded_android 把项目添加你的远程仓库
6. git remote update 把android0的分支拿到你本地
7. git fetch upstream master 把android0的maser分支更新到本地
8. git rebase upstream/master 更新合并
9. 如果你完成修改，使用 git push -u origin dev 提交更新
10. 然后进入你的github网站申请pull request

日常更新，之后更新使用如下命令

1. git remote update upstream 把android0的修改更新到本地
