make alpm_strerror binding friendly
I'm currently working on python bindings for alpm written in pyrex. While working i found that declaring alpm_strerror as char * alpm_strerror (void) instead of char * alpm_strerror (int err) and then using pm_errno in the implementation instead of err, could make it more bindings-friendly. Dan: cleaned up and added void to declaration. Instead of replacing existing function, add a new function called 'alpm_strerrorlast(void)'.
