here CLI commands.

connection, the child needs it since we do not accept CLI here
documents on unauthorized CLI connections.

Make the mgr-child CLI connection authorized in the child so we
accept CLI here documents.

Add testcase for this.

Fixes #917

rely on cli->cmd which is (by purpose) incomplete for here documents.

recover it when -spersistent reloads

-spersistent changed the requirements a fair bit, and amongst other
things introduced a ban timestamp as a unique identifier of a ban,
and the need to save and reinstate a ban.

The way this was implemented somewhat less than elegant, but we had
little choice due to the way regexps work, and amongst other horrors
it involved too much parsing and quoting of bans as text strings.

Since then we have switched to PCRE, which compiles regexps to
a bytestream which can be saved offline, and this paved the way
for this rewrite.

Instead of a datastructure with a list of tests to be carried out,
build a byte-string which encodes the same information, along with
additional information (the uncompiled regexp) to allow the ban to
be reconstructed for display in ban.list.

Include the ban timestamp as the first 8 bytes of the ban specification,
to eliminate obj->ban_t, saving 8 bytes per object.

Additional polishing to be expected.
