This function sets a callback that is invoked after the socket is
created, but before the connection is established. This is an ideal
time to customize various socket options.
Introduce `ares_txt_ext` structure with an extra `record_start`
field, which indicates a start of a new TXT record, thus allowing to
differentiate the chunks in the same record, from a chunks in a
different record.
Introduce a new API method: `ares_parse_txt_reply_ext` that works with
this kind of struct.
Add user-visible entrypoints ares_{get,set}_servers_ports(3), which
take struct ares_addr_port_node rather than struct ares_addr_node.
This structure includes a UDP and TCP port number; if this is set
to zero, the channel-wide port values are used as before.
Similarly, add a new ares_set_servers_ports_csv(3) entrypoint, which
is analogous to ares_set_servers(3) except it doesn't ignore any
specified port information; instead, any per-server specified port
is used as both the UDP and TCP port for that server.
The internal struct ares_addr is extended to hold the UDP/TCP ports,
stored in network order, with the convention that a value of zero
indicates that the channel-wide UDP/TCP port should be used.
For the internal implementation of ares_dup(3), shift to use the
_ports() version of the get/set functions, so port information is
transferred correctly to the new channel.
Update manpages, and add missing ares_set_servers_csv to the lists
while we're at it
Allow explicit configuration of the channel's sortlist, by
specifying a string in the same format as the equivalent
/etc/resolv.conf option.
This allows library users to perform the same configuration
that is available via /etc/resolv.conf, but without needing
to change that file.
Add a new ares_library_init_mem() initialization function for the
library which allows the library user to specify their own malloc,
realloc & free equivalents for use library-wide.
Store these function pointers in library-wide global variables,
defaulting to libc's malloc(), realloc() and free().
Change all calls to malloc, realloc and free to use the function pointer
instead. Also ensure that ares_strdup() is always available
(even if the local environment includes strdup(3)), and change the
library code to always use it.
Convert calls to calloc() to use ares_malloc() + memset
Make sure that the symbols are always exported and present in c-ares.
Make the headers prefixed with 'ares'.
Removed the inet_ntop.h version as it no longer features any content.
I need to do SOA queries, so here is a parser for them.
- ares_soa_reply: new struct
- ares_malloc_data/ares_free_soa: ARES_DATATYPE_SOA_REPLY
- ares_parse_soa_reply: actual function
Add 3 new functions to set the local binding for the out-going
socket connection, and add ares_set_servers_csv() to set a
list of servers at once as a comma-separated string.

ares_addr6ttl in order to prevent name space pollution, along with
necessary changes to code base and man pages.This change does not break
ABI, there is no need to recompile existing applications. But existing
applications using these structs with the old name will need source code
adjustments when recompiled using c-ares 1.6.1.
to return a linked lists of results. These were also modified to internally
use the ares_data memory struct and as such its result must be free'ed with
ares_free_data().

ares_parse_txt_reply() current version:
- Fixed a couple of potential double free's.
- Fixed memory leaks upon out of memory condition.
- Fixed pointer arithmetic.
- Setting ntxtreply to zero upon entry for all failure cases.
- Changed data type to size_t for variables substr_len, str_len and
the length member of ares_txt_reply struct.
- Avoided a couple of memcpy() calls.
- Changed i data type to unsigned int to prevent compiler warnings.
- Adjusted a comment.
- Use ARES_SUCCESS literal for successfull completion.
- Added CVS Id tag.
