Always copy dockerinit locally, regardless of whether our docker binary is static, because even it might get deleted or moved/renamed
Add dockerinit SHA1 and path to "docker info" when debug mode is enabled
Allow packagers to specify a custom dockerinit lookup location via DOCKER_INITPATH in dynbinary

Only necessary if distro policy dictates that the path deviate from the paths already listed in utils/utils.go - please refrain from using it otherwise.
Handle compressed tars in ApplyLayer

When pulling from a registry we get a compressed tar archive, so
we need to wrap the stream in the right kind of compress reader.

Unfortunately go doesn't have an Xz decompression method, but I
don't think any docker layers use that atm anyway.
Tidy up some of the error messages from apt during build
archive: Re-add XZ compression support

This shells out to the xz binary to support .tar.xz layers, as
there is no compression/xz support in go.

Move root symlink check to engine.New

Since commit c91c365, when starting the docker daemon without an
existing /var/lib/docker directory, it fails with:

  2013/12/18 23:39:36 Unable to canonicalize root (%!s(*string=0xc210077c80)): lstat /var/lib/docker: no such file or directory

Move the symlink checking code to engine.New after the root dir has been
created.
