* Cleanup up some error enum values
* Revamped the 'pmserver_t' functionality. Less allocation,
removed a param and cleaned up some duplicate URL parsing
* 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
* 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.
