lxc_init: don't mount filesystems

We have an extensive set of container config options to do this
for us, and doing this unconditionally breaks several use cases.
For instance, if we want to bind mount a /dev/shm using the
container configuration, then lxc-execute, then lxc-init will
rudely unmount the /dev/shm and remount it as a private tmpfs.

console: dump ringbuffer to disk on container exit

The console ringbuffer will be dumped to disk if the console log file is not
rotated and it's size is not unlimited. In the former two cases we will have
all data from the ringbuffer available anyway.

confile: add lxc.console.size

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.
