Avoid segfaults whet calling alpm_option_get_* before initialization

Browse Source 
When calling a function of the alpm_option_get_* group, you get a segfault
if you don't call alpm_initialize() first. With this patch those functions
set pm_errno to PM_ERR_HANDLE_NULL and return an error value if handle ==
NULL.

(Dan: modified to meet pacman coding standards)
