Note: ans6/ans6.py is a helper script that allows tests.sh to open/close
TCP connections to some BIND instance.

This variable will report the maximum number of simultaneous tcp clients
that BIND has served while running.

It can be verified by running rndc status, then inspect "tcp high-water:
count", or by generating statistics file, rndc stats, then inspect the
line with "TCP connection high-water" text.

The tcp-highwater variable is atomically updated based on an existing
tcp-quota system handled in ns/client.c.

Add {isc,ns}_stats_{update_if_greater,get_counter}() functions that
are used to set and collect high-water type of statistics.

The isc_stat_t type was too similar to isc_stats_t type, so the name was
changed to something more distinguishable.

For TCP high-water work, we need to keep the used integer types widths
in sync.

Note: int_fast32_t is used on WIN32 platform

Do not flush the cache for `rndc validation status`

See merge request !2462

And add a note to the man page that `rndc validation` flushes the
cache when the validation state is changed. (It is necessary to flush
the cache when turning on validation, to avoid continuing to use
cryptographically invalid data. It is probably wise to flush the cache
when turning off validation to recover from lameness problems.)

Include all views in output of `rndc validation status`

See merge request !2461

The implementation of `rndc validation status` iterates over all the
views to print their validation status. It takes care to print newlines
in between, but it also used put a nul byte at the end of the first view
which truncated the output.

After this change, the nul byte is added at the end so that it prints
the validation status in all views. The `_bind` view is skipped
because its validation status is irrelevant.

digdelv: Extra quotes prevent IPv6 runs

See merge request !2390

Portion of the digdelv test are skipped on IPv6 due to extra quotes
around $TESTSOCK6: "I:digdelv:IPv6 unavailable; skipping".
