* Greatly simplify and de-obfuscate the autogen and autoclean code.
* Add a bunch of the autotools required files to the repository. This
will give us consistency (a novel idea) across all builds, and allow
for much more recent versions of config.guess and config.sub to be used.
* Added alpm_list_remove_node for single list node removal
* Proper error checking/output for failed db_read/db_write (missing files)
* Invalid packages (missing files) are now removed from the package cache
* -Qs and -Ss output now look the same
* config.rpath causes errors on one machine I had, so I added it to CVS
* Fixed a "clobbered memory" issue when installing groups - only the outer list
should be free'd, not the contained data
