* 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
