pacman/lib/libalpm/deps.h
Nagy Gabor e63366ae5e 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.]
