* Removed some unnecessary headers and library links
* Made things static if possible
* Cleaned up makefiles a bit
* Fixed some old comments in the code
* Fixed some errors the static code checker splint pointed out
* Backwards arguments in a memset call in _alpm_db_read (could have been worse)
* Other various small fixes

Other:
* Default to 80 columns when getcols cannot determine display width
* Removal of ._install as a valid install file in packages
