New remove option : -u / --unneeded (FS#6505).
With --unneeded option 'pacman -R' doesn't stop in case of dependency error; it removes the needed-dependency targets from the target-list instead. See also: http://archlinux.org/pipermail/pacman-dev/2007-October/009653.html . The patch also adds a new causingpkg field to pmdepmissing_t which indicates the to-be-removed package which would cause a dependency break. This is needed, because miss->depend.name may be a provision. miss->causingpkg will be useful in -R dependency error messages too. [Xavier: renamed inducer to causingpkg, removed the _alpm_pkgname_pkg_cmp helper function as requested by Aaron. This might be added by a further commit. Other small cleanups, updated manpage and bash completion.] Signed-off-by: Chantry Xavier <shiningxc@gmail.com>
