Numerous changes:

*   Furthered the "lazy caching" to force the pkgcache to read nothing
    (INFRQ_NONE) by default.  Anything requiring package data should now check
    the infolevel of each package and attempt to update it.  This could be
    ironed out a bit more later (by using the front-end get_info function
*   Switched to libfetch.  Drastic changes to the download code and the callback
    progress bar functions.  Also fixed the return value of
    _alpm_downloadfiles_forreal.  Downloading now supports http, ftp, https, and
    files urls, along with 'mtime's and numerous other fancy features from
    libfetch.
