This adds the lxc.seccomp.allow_nesting api extension. If
lxc.seccomp.allow_nesting is set to 1 then seccomp profiles will be
stacked. This way nested containers can load their own seccomp policy on
top of the policy that the outer container might have applied.

This is modeled after LXD's API extension checks. This allows API users
to query the given LXC instance whether a given API extension is
supported.

Current we have a few minor grammatical errors in the documentation for
lxc container configuration.
Fix minor grammatical errors.

Unprivileged containers are not compatible with sharing the
host namespace due to an inability to mount sysfs. Add docs
in lxc.container.conf to document that out.

Set the signal to be sent to the container's init when the lxc monitor exits.
By default it is set to SIGKILL which will cause all container processes to be
killed when the lxc monitor process dies.
To ensure that containers stay alive even if lxc monitor dies set this to 0.

When a bare environment variable is specified then retrieve the value from the
current environment. For example, setting
lxc.environment = PATH
will cause LXC to inherit the value of PATH from the current environment.

We've announced quite a while back and printed out errors and warning everytime
someone used the aufs driver.

- remove legacy binaries
- conditionalize creation of docs and tests for the command line tools and the
shared library helper commands

This allows users to only compile the shared libray without having to compile
any of the command line tools or command helpers for the shared library.

lxc.console.size regulates the size of the console log file. This is intended
to replace lxc.console.buffer.logfile. The current semantics are:
- if lxc.console.size is not set:
- no limit is placed on the size of the log file
- if lxc.console.size is set:
- if lxc.console.rotate is set and the next write would exceed the limit:
- write as much as possible into the old log file
- rotate the log file
- write as much as posible into the new log file
- discard remaining bytes (scenario shouldn't be possible in normal
circumstances)
- if lxc.console.rotate is not set and the next write would exceed the limit:
- keep overwriting the current log file
To make the log file a mirror of the in-memory ringbuffer simply set:
lxc.console.buffer.size == lxc.console.size.
