sync: As pointed out by Andrew Gregory there could be an error when adding duplicates if they are two separate packages with the same name. Add a check in alpm_add_pkg() to test whether the duplicate is actually the same package, and if so, log a debug message and return success to skip the package. If the duplicate is a different package return ALPM_ERR_TRANS_DUP_TARGET and treat that error just like any other error in pacman. remove: Change alpm_remove_pkg() to just log a debug message and return success to skip duplicates. Remove the handling of ALPM_ERR_TRANS_DUP_TARGET in pacman. Also fixes FS#49377.
