Note: even not fully optimized, snprintf is already much faster in at least one benchmark.
examples/ipv4addr.c modified to use snprintf runs about 10x faster when using qrintf-gcc.
$ gcc -Wall -O2 examples/ipv4addr.c && time ./a.out 1234567890
result: 73.150.2.210
real 0m2.402s
user 0m2.396s
sys 0m0.002s
$ bin/qrintf-gcc -Wall -O2 examples/ipv4addr.c && time ./a.out 1234567890
