This allows a user to send a signal to all the processes in the
container within a single atomic action to avoid new processes being
forked off before the signal can be sent.
This is basically taking functionality that we already use being
`delete` and exposing it ok the `kill` command by adding a flag.

This enables support for exec command argument starting with a '-'.
This uses the usual argument separator '--', for example:
runc exec containerid -- ps -afx
Without this, cli interprets command argument and fails with
'flag provided but not defined'.

Currently, ps command can not support argument:
(But following usage is in manual)
| # ./runc ps 123 -ef
| Incorrect Usage.
|
| NAME:
| runc ps - ps displays the processes running inside a container
|
| USAGE:
| runc ps [command options] <container-id> [ps options]
|
| OPTIONS:
| --format value, -f value select one of: table or json
|
| flag provided but not defined: -ef
| #
Instead of using odd command like:
| # ./runc ps -- 123 -ef
We can make it seems little better:
| # ./runc ps 123 -- -ef
| UID PID PPID C STIME TTY TIME CMD
| root 29046 29038 0 11:18 pts/2 00:00:00 sh
| #
This patch also fixed manual which can not working in current
code.

Argument of "ps options" for ps command is a optional parameter.
Should use [] instead of <> in manual.
Signed-off-by: Zhao Lei <zhaolei@cn.fujitsu.com>
The major change is the description of options, change
it as the latest cli help message shows, which specify
a "value" after an option if it takes value, and add
(default: xxx) if the option has a default value.
This also includes some other minor consistency fixes.

This patch add losted --no-subreaper and --no-pivot options in
manual:
# ./runc restore --help
..
OPTIONS:
...
--no-subreaper disable the use of the subreaper used to reap reparented processes
--no-pivot do not use pivot root to jail process inside rootfs. This should be used whenever the rootfs is on top of a ramdisk

The description contents in manual is for --format argument
actually, see:
# ./runc list --help
...
OPTIONS:
--format, -f select one of: table or json.
The default format is table. The following will output the list of containers
in json format:
# runc list -f json
--quiet, -q display only container IDs
#
This patch move above content into right place, and remove the command
example which is not necessary.

There are 3 types of EXAMPLE title in manual and code:
1: "# EXAMPLE"
runc-delete.8.md
runc-exec.8.md

2: "EXAMPE:"
runc-spec.8.md
3: EXAMPLE title exist in manual, but not exist in code's --help output
