Reverse zone suggestions: yours and public, dismiss, per-view switch; child zones take their records

Suggestions split into networks that are yours (private IPv4 /24, ULA /48, an IPv6 /48 this server has an address in), which Create all creates, and public addresses (/32 or /128) to create only if they are yours or dismiss. A view can turn suggestions off, which also keeps it out of choosing a reverse zone's view (database version 13). A zone created inside another in the same view takes the parent's records under it; a delegation and its glue stay, a linked parent keeps them with a warning.
