Latencystats uses unnecessary floating point and is inaccurate if the number
of cycles per ns is not an integral value. Cleanup the code and add
more tests as well.

v6 - rebase and combine updates to test

Stephen Hemminger (8):
  latencystats: replace use of VLA
  latencystats: handle fractional cycles per ns
  latencystats: do not use floating point
  latencystats: fix log messages
  latencystats: update include files
  latencystats: enforce that unused callback function is NULL
  latencystats: add metric for number of samples
  test: update to latencystats tests
