Move DB and cache dirs away from there dependence on ROOTDIR

This change allows us to use all autoconf specified paths, most notably
$(localstatedir). It is quite a change and touches a lot of files, as
all references to the DB and cache were done with the ROOTDIR as a prefix.

* add --lock command-line option to pacman to specify the location of the
  lockfile (this can now be specified at configure time by setting the
  $localstatedir path).
* Rip quite a few settings out of configure.ac as they are now picked by
  setting the paths during configure or make.
* Fix bug with /tmp fallback for sync downloads not working correctly
  (related to root location, now the system tmp dir is used).
* Simplified the parameters to some libalpm functions, and added get/set
  for the new lockfile option.
* Renamed several of the DEFS to names without the PM_ prefix.
