* apt-pkg/contrib/fileutl.cc:

  - add a parent-guarded "mkdir -p" as CreateDirectory()
* apt-pkg/acquire.{cc,h}:
  - add a delayed constructor with Setup() for success reporting
  - check for and create directories in Setup if needed instead of
    error out unfriendly in the Constructor (Closes: #523920, #525783)
  - optional handle a lock file in Setup()
* cmdline/apt-get.cc:
  - remove the lock file handling and let Acquire take care of it instead
