implement the function even when h_errno is not a macro.
The h_errno macro test now only done on systems for which there
is no hard coded knowledge about getaddrinfo's thread safeness.
- Constantine Sapuntzakis reported that Darwin 6.0 a.k.a. MAC OS X 10.2
and newer have a threadsafe getaddrinfo.
- Fix Dragonfly BSD triplet detection.
- In case the hard-coded knowledge says that getaddrinfo is threadsafe,
an additional check is done to verify that h_errno is also defined.
If h_errno isn't defined, we finally assume that it isn't threadsafe.
Jamie Lokier provided the inspiration for this extra check.
c-ares libraries in debug and release flavours.
Additionally each of the three sample programs is built against
each of the four possible c-ares libraries, generating all this
a total number of 12 executables and 4 libraries.
c-ares with --enable-curldebug uses memdebug.h from libcurl's lib subdirectory.
memdebug.h needs access to libcurl's setup.h from libcurl's lib subdirectory
and also needs access to libcurl's generated curl_config.h

macro names and some internal variables used for them.

shows that this one is actually a modified copy of ares_parse_a_reply.c.
In order to comply with ares_parse_a_reply.c's M.I.T. license, the old
1998 M.I.T. copyright notice is now also preserved in this file the same
as it is done in other ares_parse_*.c files.
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.
