Changed paths: M libknet/links.c M libknet/tests/api_knet_link_set_ping_timers.c

Log Message: ----------- links: fix ping interval and pong timeout value checking

warn if ping interval is lower than thread timer resolution as it has no effects

error if ping timeout is lower than thread timer resolution as it causes links to be highly unstable

Changed paths: M libknet/threads_rx.c

Log Message: ----------- rx: allow links to be active faster

scenario: node A and node B

node A completes ping/pong link up process faster than B node A starts to send data to node B

old behavior: node B would unconditionally discard data packets

new behavior: node B will check internal link status to see if ping/pong link up process is in progress.

if the link is sending pings and receiving pongs, it´s safe to assume that the link will go up (since we are also receiving data from the node A). node B will speed up link up and accept data immediately.

This should address a overall init race condition when nodes startup are slighly off by enough milliseconds to cause 2 memeberships to form and see fencing fireworks.

Changed paths: M libknet/tests/api_knet_handle_set_threads_timer_res.c M libknet/threads_common.c

Log Message: ----------- threads: add config check to match min value with pong timeouts

avoid network instability and dump full report of nodes/links that would have caused problems
