BUG/MINOR: chunk: fix chunk_appendf() to not write a zero if buffer is full
If the buffer is completely full, the function chunk_appendf() would
write a zero past it, which can result in unexpected behavior.
Now we make a check before calling vsnprintf() and return the current
chunk size if no room is available.
This should be backported as far as 2.0.
