  Implement global/system file search paths
  
  The goal of this work is to expose the search logic for "global",
  "system", and "xdg" files through the git_libgit2_opts() interface.
  
  Behind the scenes, I changed the logic for finding files to have a
  notion of a git_strarray that represents a search path and to store
  a separate search path for each of the three tiers of config file.
  For each tier, I implemented a function to initialize it to default
  values (generally based on environment variables), and then general
  interfaces to get it, set it, reset it, and prepend new directories
  to it.
  
  Next, I exposed these interfaces through the git_libgit2_opts
  interface, reusing the GIT_CONFIG_LEVEL_SYSTEM, etc., constants
  for the user to control which search path they were modifying.
  There are alternative designs for the opts interface / argument
  ordering, so I'm putting this phase out for discussion.
  
  Additionally, I ended up doing a little bit of clean up regarding
  attr.h and attr_file.h, adding a new attrcache.h so the other two
  files wouldn't have to be included in so many places.
