Gao feng d45be919cd change socketpair to pipe 
If one pair of pipe created by socketpair closed, the other side
will receice error, so other side cannot know the exec result of
peer.

Use pipe to replace socketpair.

Gao feng 08764d5bbc fix incorrect logic of hyper_send_type_block 
It means set fd block first and send out the type.
And fix the access to exec consurrently, hyper init
should be blocked until do_exec_cmd processes the
exec struct.

Gao feng 749387bbfa fix possible missing eof data 
It happend that pts_loop reads all of the data before the,
SIGCHLD signal being handled, so only hup handler will be triggered,
move the sending eof message to hup handler.

Gao feng a8362c1a70 hold the fd of container pts device in hyper init 
1, Hold the the file description of pts device and ptmx in hyper-init process
2, Dup fd to the stdio of Exec cmd
3, Exec cmd exited, no EPOLLHUP event since the file is still open
4, Try to read ptmx fd before close pts fd
4, signal handler get signal SIGCHLD, close the pts fd to trigger EPOLLHUP event
5, EPOLLHUP event is received, send eof message to ttyfd. release exec.

Gao feng 2262bc18fe accept read raw data from write message 
It's difficult to encode the json with special characters such as '"', '>'...
encoding and unicoding these characters will change the length of json message,
it's a pain to get bytes contains these characters from json.

This patch allows to read the bytes contains special character outside the json.
for example:
{"container":"c5f67934326d2ecef59fee62148bc9237e2481cd803cc0760a6406da15f4ee60","file":"/tmp/aaa"}sssssss

Gao feng c862b89079 running contianers in the pid ns of pod init 
manpage of setns says:

>CLONE_NEWPID behaves somewhat differently from the other nstype values: reassociating the calling thread with a PID namespace changes only the PID namespace that child processes of the  caller  will
>be created in; it does not change the PID namespace of the caller itself.  Reassociating with a PID namespace is allowed only if the PID namespace specified by fd is a descendant (child, grandchild,
>etc.)  of the PID namespace of the caller.  For further details on PID namespaces, see pid_namespaces(7).

so clone a temporary process to enter pid ns, and then create containers. and join them to the other nss of pod init.
