* Add --pacing-timer option to allow tuning of -b timers.
These control the granularity of the timer and hence burstiness
of iperf3's sends. The default is 1ms (1000), which is the default
starting with iperf 3.2. Follow-on to the commit in #460.
* Update manpage and release notes for --pacing-timer.
This involves copying the release notes through 3.0.11 into the
mainline release notes file, and then updating for changes on the
mainline that haven't appeared in any prior 3.0.x release. Not all
changes are listed.
We'll probably do a beta or two before a real 3.1.0 release.
Mostly this change consists of adding FreeBSD-specific code to handle
this feature. The concepts and system calls are very similar to what's
already done for Linux. One difference is that on FreeBSD, the CPU
affinity mask is saved before -A processing and restored afterwards.
This causes a slight change to the function signatures for
iperf_setaffinity() and iperf_clearaffinity() (these functions
however are not documented as a part of the libiperf3 API).
Slightly improve some of the documentation for the -A command line
option, to hopefully stave off some of the questions about this
feature.
Mostly based on a submitted patch.
Issue: 128 (better error message for CPU affinity failure)

These go to a new section that might be merged with the prior 3.0.0
section pending a release engineering discussion.
Also fix a typo: s/vebose/verbose/
