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
The old default didn't work even for moderate cases.
(eg. strlen(name) == 17, two ipv4 addresses, on 64-bit sim)

dc8c814ca3 Squashed commit of the following:
Fixed coding standard error in several files.  Use of while( is incorrect; a space is required between while and (.  Also ran tools/nxstyle and fix thoses complaints as well in most files.

    Changes to comply with coding standard.  Mostly focused on files with missing space after keyword in if(, switch(, and for(.  Offending files also got changes to comply with tools nxstyle.  If there were logs of nxstyle complaints, the file also got a taste of tools/indent.sh.  Still need to fix occurrences of while( with missing space.  There are a lot of them.
