Renamed for consistency. Also, since print_int() and print_str() are
already defined as macros, the long name version is preferred.

Having a string callback is much more simpler than a variable args
one for writers to deal with, especially when dealing with escaping.

This patch also introduces a local fast_asprintf() function which is
similar to av_asprintf() but avoids reallocating at each print (leading
to a performance issue).
