Those are a wrapper around xbps_{array,dictionary}_internalize_from_zfile()
that prints a debugging msg when the plist file cannot be internalized.
Update xbps to use these wrappers.
Rather than using a random buffer from stack or heap, and decide
what size to use, create a private memory mapped object...
This simplifies the code in lib/verifysig.c and xbps-create.
