Add support for Mythic Beasts Dynamic DNS

Browse source 
This is called `mythicdyn`, to differentiate from their more general zone
file editing, support for which could be added in future (it works similarly
to Gandi’s).

This patch also adds support for error code 403, which Mythic uses, and
improves the error message for 401.

o 'mythicdyn'
The 'mythicdyn' protocol is used by the Dynamic DNS service offered by
www.mythic-beasts.com.
Configuration variables applicable to the 'mythicdyn' protocol are:
protocol=mythicdyn ##
ipv6=no|yes ## whether to set an A record (default, ipv6=no)
## or AAAA record (ipv6=yes).
login=service-login ## the user name provided by the admin interface
password=service-password ## the password provided by the admin interface
fully.qualified.host ## the host registered with the service
Note: this service automatically sets the IP address to that from which the
request comes, so the IP address detected by ddclient is only used to keep
track of when it needs updating.
Example ${program}.conf file entries:
## Single host update.
protocol=mythicdyn, \\
login=service-login \\
password=service-password, \\
host.example.com
## Multiple host update.
protocol=mythicdyn, \\
login=service-login \\
password=service-password, \\
hosta.example.com,hostb.sub.example.com
