Merge revision 1826467 from 10.14 to trunk. Original commit message:

Remove support for COMMAND_TESTCONNECTION connectToDatabase feature.
It was never documented, and was never part of the regression tests.

A new regression test demonstrates that attempting to use this feature
now results in a "usage" response from the Network Server.

Also, change the Network Server's default security policy file, as well
as the template security policy file that we distribute with the
release and in the documentation. The new policy files do not use
the <<ALL FILES>> permission; instead they restrict the permission
to certain directories only.

Also, change the implementation of the Network Server's "sysinfo"
sub-command. Prior to this change, that feature would open each
jar file on the Network Server's class path, and would report on
whatever information it could find about that jar file. Now, the
only jar files that are opened and reported on are the known Derby
jar files; a table of those jar file names is compiled into the
sysinfo command. This causes sysinfo to return less information,
but it also means that it only needs the permission to access the
known Derby jar files on the classpath.
