lib-dns: Allow setting the ioloop that the dns_lookup/dns_client is started on.

Updated copyright notices to include the year 2018.

global: use i_close_fd{,_path}() instead of open-coding them

global: Replaced all instances of memset(p, 0, sizeof(*p)) with the new i_zero() macro. Used the following script: C_FILES=`git ls-files *.c` H_FILES=`git ls-files *.h` for F in "$C_FILES $H_FILES"; do echo "$F" perl -p -i -e 's/safe_memset\(&\(?([^,]*)\)?,\s*0,\s*sizeof\(\g1\)\)/i_zero_safe(&$1)/g' $F perl -p -i -e 's/safe_memset\(([^,]*),\s*0,\s*sizeof\(\*\g1\)\)/i_zero_safe($1)/g' $F perl -p -i -e 's/memset\(&\(?([^,]*)\)?,\s*0,\s*sizeof\(\g1\)\)/i_zero(&$1)/g' $F perl -p -i -e 's/memset\(([^,]*),\s*0,\s*sizeof\(\*\g1\)\)/i_zero($1)/g' $F done

lib: remove autoclose parameter from [io]_stream_create_fd Use [io]_stream_create_fd_autoclose() for autoclose.

global: freshen copyright git ls-files | xargs perl -p -i -e 's/(\d+)-201[0-5]/$1-2016/g;s/ (201[0-5]) Dovecot/ $1-2016 Dovecot/'

lib-dns: The dns_lookup() call caused a crash upon a connect error, because dns_client_disconnect() can indirectly call itself recursively. Solved by dropping the list of lookups from the client object before the lookups are destroyed.

lib-dns: Added dns_client_switch_ioloop().

lib-dns: Fixed handling failed DNS lookups.

Updated copyright notices to include year 2014.

Fixed sscanf() error handling. Patch by Jann Horn.

lib-dns: If existing dns connection dies in write(), retry connect once.

lib-dns: Fixed handling write() failure to dns-lookup server process.

lib-dns: Fixed busy looping when dns-client disconnected.

lib-dns: Added alternative API for doing longer connections to dns-client process.

lib-dns: Close dns-client fd before calling callback. Just in case the callback is slow and keeps the fd unnecessarily long open.

lib-dns, dns: Don't use IPv4-only error codes

dns, lib-dns: Added support for async DNS PTR lookups.

Oops :) Update copyrights to 2013 without breaking all .c files.
