Diego FronzaandOndřej Surý 66fe8627de Added TCP high-water statistics variable 
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.

Diego FronzaandOndřej Surý a544e2e300 Add functions for collecting high-water counters 
Add {isc,ns}_stats_{update_if_greater,get_counter}() functions that
are used to set and collect high-water type of statistics.

Diego FronzaandOndřej Surý eb5611a770 Change the isc_stat_t type to isc__atomic_statcounter_t 
The isc_stat_t type was too similar to isc_stats_t type, so the name was
changed to something more distinguishable.

Michał KępieńandOndřej Surý e21103f2d3 Fix statistics for x86 Windows builds 
Using atomic_int_fast64_t variables with atomic functions on x86 does
not cause Visual Studio to report build errors, but such operations
yield useless results.  Since the isc_stat_t type is unconditionally
typedef'd to atomic_int_fast64_t, any code performing atomic operations
on isc_stat_t variables is broken in x86 Windows builds.  Fix by using
the atomic_int_fast32_t type for isc_stat_t in x86 Windows builds.
