In order to lower the amount of memory allocated at startup by named
instances used in the BIND system test suite, set the default value of
"max-cache-size" for these to 2 megabytes. The purpose of this change
is to prevent named instances (or even entire virtual machines) from
getting killed by the operating system on the test host due to excessive
memory use.
Remove all "max-cache-size" statements from named configuration files
used in system tests ("checkconf" notwithstanding) to prevent confusion
as the "-T maxcachesize=..." command line option takes precedence over
configuration files.

The merge also needed to update files in legacy and tcp system tests
(newly introduced in master after branch was created) to introduce use
of lockfile.
3620. [func] Added "rpz-client-ip" policy triggers, enabling
RPZ responses to be configured on the basis of
the client IP address; this can be used, for
example, to blacklist misbehaving recursive
or stub resolvers. [RT #33605]
3619. [bug] Fixed a bug in RPZ with "recursive-only no;"
[RT #33776]
