Details:

The attached pbuf_printf.patch adds pbuf_printf() and applies on top the
patches in #7454.  This patch uses the format library (library source not
included here, see: http://code.google.com/p/format/) to enable sprintf()-like
functionality on a pbuf chain.  The pbuf chain must be long enough to hold the
result.  It uses pbuf_memcpy() and therefore requires a call to
pbuf_memcpy_cleanup() before sending it with tcp_write().
