Add new alpm_list_remove_item() function
This takes in the list and a list item, and does the pointer dance necessary to remove it from the list regardless of whether it is first, last, or somewhere in the middle. It is useful for callers that already know what item needs to be removed and have a pointer to it rather than doing a search by data that the plain alpm_list_remove() does. Refactor alpm_list_remove() to use this function as well. Signed-off-by: Dan McGee <dan@archlinux.org>
