Use size_t for alpm_list sizes

There is a lot of swtiching between size_t and int for alpm_list sizes
in the codebase.   Start converting these to all be size_t by adjusting
the return type of alpm_list_count and fixing all additional warnings
given by -Wconversion that are generated by this change.

Dan: a few more small changes to ensure things compile, adjusting some
printf format string characters to accommodate the larger size on x86_64.
