> o ticket 314: eliminate the udp accept race between listener and server thread using a conditional signal
> o ticket 313: remove support for configure --enable-static-bin, never worked and only misleads
> o ticket 312: regression, fix for segv in UDP summing enhance outputs
> o ticket 311: histogram worst timestamp needs proper formatting, didn't print leading zeros for the usec portion
> o ticket 310: regression on client setting reports, too many with things like -P > 1
> o ticket 309 (regression): udp summing is broken. Need to reset sum event counters after interval reports
> o ticket 308: -P should be order independent
> o ticket 305: add support for --skip-rx-copy w/tcp. Set recv flags to MSG_TRUNC when the payload isn't needed by iperf
> o ticket 157 (regression since 2.1.4): remove AM_CONDITIONAL for TUN & TAP. Move the AF_PACKET AM_CONDITIONAL to its own scope. Rerun autoreconf automake

> o remove settings report for client threads when P > 1
> o fix timeval outputs to use %06ld for usecs
