"masters" and "default-masters" are now flagged so they will
not be included in the named.conf man page, despite being
accepted as valid options by the parser for backward
compatibiility.
This commit extends ACL syntax handling code with 'port' and
'transport' options. Currently, the extended syntax is available only
for allow-transfer options.
Add support for a "tls" key/value pair for zone primaries, referencing
either a "tls" configuration statement or "ephemeral". If set to use
TLS, zones will send SOA and AXFR/IXFR queries over a TLS channel.
as "type primary" is preferred over "type master" now, it makes
sense to make "primaries" available as a synonym too.
added a correctness check to ensure "primaries" and "masters"
cannot both be used in the same zone.
