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)'.
