Move
	- ovl_get_rootfs_dir()
	- mount_entry_create_overlay_dirs()

from conf.h to overlay.{c,h} where they belong.

Rename
	- mount_entry_create_overlay_dirs() --> ovl_mkdir()

in accordance with the ovl_ prefix naming scheme for types and functions
associated with overlay.

Take the chance to add whitespace between operators where missing.

With this commit we start to split bdev.{c,h} into modules located in the
subfolder bdev. We start by creating a module for overlay: overlay.{c,h}.

- The functions:

	- overlayfs_detect()
	- overlayfs_mount()
	- overlayfs_umount()
	- overlayfs_clonepaths()
	- overlayfs_destroy()
	- overlayfs_create()

  move from bdev.{c,h} to overlay.{c,h}. The only thing that remains in bdev.c
  is the static definition of

	- static const struct bdev_ops overlayfs_ops

- The functions:

	- update_ovl_paths()
	- overlay_getlower()

  move from lxccontainer.c to overlay.{c,h}. update_ovl_paths() is used to
  update absolute paths for overlay lxc.mount.entry entries but it seems to fit
  more here than into lxccontainer.c.
  The Function overlay_getlower() is used to extract the lower directory for
  overlay (and aufs) rootfs. It should at some point become a common helper.

- The functions:

	- do_rsync()
	- dir_new_path()

   remain in bdev.c for now but become extern. We declare them extern in
   overlay.c to be able to call them. As the comment to them correctly notices,
   they should at some point become common helpers and probably move to
   utils.{c,h} or some other more appropriate place.

- The structs:

	- struct bdev; /* defined in bdev.h */
	- struct bdev_specs; /* defined in lxccontainer.h */
	- struct lxc_conf; /* defined conf.h */

  are forward declared/put as incomplete types in overlay.h so that the
  functions have access to it.

- The header overlay.h is *not* included in bdev.h but only in bdev.c so that
  when bdev.h is included the public functions in overlay.h cannot be accessed,
  i.e. if an implementation wants to call functions from overlay.h they need to
  explicitly include it. (As is e.g. done in the case of lxccontainer.c.)

- The header

	- lxc-btrfs.h

  also moves to the bdev subfolder.

- Adapt Makefile.am to the new bdev layout.

This patch adds a new ->migrate API call with three commands:

MIGRATE_DUMP: this is basically just ->checkpoint()
MIGRATE_RESTORE: this is just ->restore()
MIGRATE_PRE_DUMP: this can be used to invoke criu's pre-dump command on the
    container.

A small addition to the (pre-)dump commands is the ability to specify a
previous partial dump directory, so that one can use a pre-dump of a
container.

Finally, this new API call uses a structure to pass options so that it can
be easily extended in the future (e.g. to CRIU's --leave-frozen option in
the future, for potentially smarter failure handling on restore).

v2: remember to flip the return code for legacy ->checkpoint and ->restore
    calls

Instead of *always* resetting the current_config to null, we should only
reset it if this API call set it.

This allows nesting of API calls, e.g. c->checkpoint() can pass stuff into
criu.c, which can call c->init_pid() and not lose the ability to log stuff
afterwards.
