3097f62511 Revert "lib/netdb: Change the default NETDB_DNSCLIENT_NAMESIZE to NAME_MAX" 
This reverts commit 3724f6be55.

Because there is no real correlation between DNS namesize and NAME_MAX
as far as I know. The former is about network and the latter is about
filesystem. While they might happen to be similar values for
some configurations, it's very confusing to use them this way.

76add63598 Bump the default of CONFIG_NETDB_DNSCLIENT_MAXRESPONSE 
It's better to have a default working for many cases.
Usually DNS servers are not optimized for embedded clients.
Users can fine tune for their environment anyway.

b36420ef32 Bump the default of CONFIG_NETDB_BUFSIZE

(eg. strlen(name) == 17, two ipv4 addresses, on 64-bit sim)
