mdns: Add MDNS_STRICT_MODE config option

Browse Source 
Strict mode was hardcoded in private header file, but it's useful for
users to enable/disable it depending on the mdns library they are using.
e.g. Avahi might not resolve the non-strict answers.

Configures strict mode. Set this to 1 for the mDNS library to strictly follow the RFC6762:
Currently the only strict feature: Do not repeat original questions in response packets
(defined in RFC6762 sec. 6).
Default configuration is 0, i.e. non-strict mode, since some implementations,
such as lwIP mdns resolver (used by standard POSIX API like getaddrinfo, gethostbyname)
could not correctly resolve advertised names.
