BUILD/MINOR: trace: fix use of long type in a few printf format strings
Building on a 32-bit platform produces these warnings in trace code:
src/stream.c: In function 'strm_trace':
src/stream.c:226:29: warning: format '%lu' expects argument of type 'long unsigned int', but argument 9 has type 'size_t {aka const unsigned int}' [-Wformat=]
chunk_appendf(&trace_buf, " req=(%p .fl=0x%08x .ana=0x%08x .exp(r,w,a)=(%u,%u,%u) .o=%lu .tot=%llu .to_fwd=%u)",
^

chunk_appendf(&trace_buf, " res=(%p .fl=0x%08x .ana=0x%08x .exp(r,w,a)=(%u,%u,%u) .o=%lu .tot=%llu .to_fwd=%u)",

chunk_appendf(&trace_buf, " - VAL=%lu", *val);

Let's just cast the type to long. This should be backported to 2.1.
