The dns_catz_generate_zonecfg() function generates a zone configuration
string to use with a new catalog zone member zone. The buffer for the
string is 512 bytes initially (ISC_BUFFER_INCR), but can be reallocated
when required, when using corresponding isc_buffer functions like
isc_buffer_reserve(), isc_buffer_putstr(), isc_buffer_copyregion(), etc.
However, the dns_name_totext() function, which expects the buffer as an
argument, doesn't automatically resize it if the name doesn't fit there,
but instead just returns ISC_R_NOSPACE.
The chance of this occurring increases when the configuration string is
large due to, for example, long zone name, long list of primary servers
which have keys configured and/or TLS configured.
Use dns_name_format() accompanied with isc_buffer_putstr() instead of
dns_name_totext().
