This patch adds additional run-time checking for invalid arguments to
CFI_establish and CFI_setpointer. It also changes existing messages
throughout the CFI_* functions to use PRIiPTR to format CFI_index_t
values instead of casting them to int and using %d (which may not work
on targets where int is a smaller type), simplifies wording of some
messages, and fixes issues with capitalization, typos, and the like.
Additionally some coding standards problems such as >80 character lines
are addressed.
