Add wrapper around asprintf calls

Not checking the return value of asprintf calls reuslts in a warning
when using -D_FORTIRFY_SOURCE=2.  This adds a simple wrapper around
asprintf calls which checks the return value.

Currently the check does nothing more than outputing a message to stderr
on failure, but that is at least an improvement over silent failures.
