Implement SNI support for the gnutls SSL plugin.

Note that gnutls is picky in regard to what it accepts as the server name - it
MUST be a domain name. IP addresses are not supported according to the
documentation.

Hence, filter out IP addresses and hope that whatever is not recognized as
such an address is actually a domain name. This will probably fail for more
exotic addresses (especially in IPv6 realm), but wiring up a full-blown parser
is too much effort and SSL plugins are not part of purple-3 anyway.

Fixes #17300
# This program takes a C header/source as the input and produces
#
# with --keyword=enum: the list of all enums
# with --keyword=struct: the list of all structs
#
# the output styles:
#
# --enum DBUS_POINTER_NAME1,
# DBUS_POINTER_NAME2,
# DBUS_POINTER_NAME3,
#
# --list NAME1
# NAME2
# NAME3
