777be10ebe ntpd: do not invalidate datapoints after step 
Used to set p->filter_datapoint[i].d_dispersion = MAXDISP
and clear reachable bits, but this proved to be too agressive:
after step (tested with suspinding laptop for ~30 secs),
this caused all previous data to be considered invalid,
making us needing to collect full ~8 datapoins per peer
after step in order to start trusting them.
In turn, this was making poll interval decrease even after
step was done. (Poll interval decreases already before step
in this scenario, because we see large offsets and end up with
no good peer to select).

760fc6debc init: halt on SIGPWR too 
Most init processes implement a handler for SIGPWR that gracefully
stops all child processes when shutting down a machine. Some other
technologies rely on this signal - e.g. Busybox powered LXC
containers.

This patch makes busybox init halt when receiving SIGPWR.

"Trimming" your NAND/eMMC storage will restore the write performance
back to normal after having slow down issues on sequential write and
random write due to usage over time.
