2019-06-05Implement dumpability tracking and checksMichael Pratt
We don't actually support core dumps, but some applications want to get/set dumpability, which still has an effect in procfs. Lack of support for set-uid binaries or fs creds simplifies things a bit. As-is, processes started via CreateProcess (i.e., init and sentryctl exec) have normal dumpability. I'm a bit torn on whether sentryctl exec tasks should be dumpable, but at least since they have no parent normal UID/GID checks should protect them. PiperOrigin-RevId: 251712714

2019-03-28set task's name when forkchris.zn
When fork a child process, the name filed of TaskContext is not set. It results in that when we cat /proc/{pid}/status, the name filed is null.
