Apply exponential smoothing to the clock rate update calculation in
clib_time_verify_frequency(), with a half-life of 1 minute and a
sampling frequency of 16 seconds. Within 5 minutes or so, the
calculation converges
With each rate recalculation: reset total_cpu_time based on the kernel
timebase delta since vpp started, and the new clock rate
Improve the "show clock [verbose]" debug CLI command.
BFD echo + echo fail tests marked off until the BFD code can be
reworked a bit.

If clib_time_verify_frequency() adjusts the clock frequency, transform
total_cpu_time to the new time coordinate space. Otherwise, we break
comparisons with previous clib_time_now() value.
Without this correction, time jumps in one direction or the other
depending on the sign of the frequency change. Reasonably harmless in
most cases, but under perfect storm conditions the wheels fall off.

Compute the first power of ten which is greater than 0.1% of the clock
rate. Save the result, and use it to round future results. The
previous constant value - 1e7 - didn't work properly on aarch64.

Also correct types.h for mips64 which could never be hit
as _mips was part of the previous ifdef.

Scan IPv4 and IPv6 neigbor pool entries once a minute to keep them
up to date. The neighbor of an entry is probed if its time-stamp
is older than 1 minute. If the neighbor respond, its time-stamp
will be updated. If there is no response from a neighbor, its
entry will be deleted when the time-stamp of the entry become more
than 4 minutes old. Static neighbor entries are not probed nor
deleted.
Implemented CLI and API to enable and disable priodic scan of IPv4,
IPv6 or both types of IP neighbors. CLI is "ip scan-neighbor" and
API is "ip_scan_neighbor_enable_disable". Other IP neighbor scan
parameters can also be changed from their defaults via the CLI/API.
