* Fix some corner cases with greedy mode, where ports would be
tracked inside httperf rather than the OS. There were handfuls
of corner cases where it'd either loop over an already-allocated
port by the OS and chew 100% of cpu with no progress. Also, hit an
already allocated port by the OS, skip/stop, but then the next lookup
would hit that port again - it would never find a new port to open.
* Add kqueue support for FreeBSD. (No, not using libevent. Yet.)
* Add a periodic stats option, to print out 200/302 counts once
every second. This is to aid in automatic scripts looking to graph
the progress being made.
* Add the ability to define multiple local client addresses, so
requests can come from a much bigger pool of IP addresses.
This allows for much more concurrency per process.)
* Add an explicit timeout on how long httperf can run - again, to aid
in automated testing.
* Add an option to allow header contents to be loaded in from a file.
* Other fixes, mostly type related fixes, thanks to clang/llvm on
FreeBSD-10.
We're using this in production at Norse to stress test out things,
upwards of 25,000 requests per second per httperf process.
