[PATCH 1/5] dnsproxy: Rename append_domain() to append_or_remove_domain()

[pasi . sjoholm]

From: Pasi Sjöholm <pasi.sjoh...@jollamobile.com>

A new append_domain()- and remove_domain()-functions which both
call append_or_remove_domain()-function by setting boolean append-
variable accordingly.

This enables a capability to remove domains from the dns-server's
domain list.
