Kernel capabilities for privileged syslog operations are currently splitted into
CAP_SYS_ADMIN and CAP_SYSLOG since the following commit:
http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=ce6ada35bdf710d16582cc4869c26722547e6f11
This patch drops CAP_SYSLOG to prevent containers from messing with
host's syslog (e.g. `dmesg -c` clears up host's printk ring buffer).
Closes#5491

This is needed for Send/Recieve to correctly handle borders between
the messages.
The framing uses a single 32bit uint32 length for each frame, of which
the high bit is used to indicate whether the message contains a file
descriptor or not. This is enough to separate out each message sent
and to decide to which message each file descriptors belongs, even
though multiple Sends may be coalesced into a single read, and/or one
Send can be split into multiple writes.

This PR aims to increase the consistency across the docs for
code blocks and code/comment/output markings.
Rule followed here is "what's visible on the screen should be reflected"
Issue:
- Docs had various code blocks showing: comments, commands & outputs.
- All three of these items were inconsistently marked.
Some examples as to how this PR aims to introduce improvements:
1. Removed `> ` from in front of the "outputs". Eg,
` > REPOSITORY TAG ID CREATED` replaced with:
` REPOSITORY TAG ID CREATED`.
2. Introduced `$` for commands. Eg,
` sudo chkconfig docker on` replaced with:
` $ sudo chkconfig docker on`
3. Comments:
` > # ` replaced with:
` # `.
> Please note:
> Due to a vast amount of items reviewed and changed for this PR, there
> might be some individually incorrect replacements OR patterns of incorrect
> replacements. This PR needs to be reviewed and if there is anything missing,
> it should be improved or amended.

No need to duplicate this information when we already have a
container.json file in the root of libcontainer

This duplicates some of the Exec code but I think it it worth it because
the native driver is more straight forward and does not have the
complexity have handling the type issues for now.

This temp. expands the Exec method's signature but adds a more robust
way to know when the container's process is actually released and begins
to run. The network interfaces are not guaranteed to be up yet but this
provides a more accurate view with a single callback at this time.

A WIP pull request or issue for discussion would be a better avenue for collaboration and discussion of a ZFS backend.

These are failing, and indicate things that need to be fixed. The
primarily problem is the lack of framing between beam messages.
