5a0a473c30 Initial support for the generic ares_free_data() function that will allow 
applications to free memory allocated and returned by some c-ares funtions.

ce6731baf1 Symbol hiding configure options renamed to the hopefully less ambiguous 
--enable-symbol-hiding and --disable-symbol-hiding as well as related
macro names and some internal variables used for them.

Related configuration file preprocessor symbols named to
CARES_SYMBOL_HIDING and CARES_SYMBOL_SCOPE_EXTERN.

d4ff44d5f6 In no particular order, changed/fixed all of the following in 
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.

0d9f14f5c1 Initial step towards the ability to reduce c-ares exported symbols 
based on the 'visibility' attribute for GNUC and __global for Sun
compilers, taking also in account __declspec function decoration
for Win32 and Symbian DLL's.

Introducing configure options --enable-hidden-symbols and
--disable-hidden-symbols following libcurl's naming.

a1cc78d5a1 John Engelhart noticed an unreleased problem relative to a duplicate 
ARES_ECANCELLED error code value and missing error code description.

f3611c2773 changed u_int16_t to unsigned short because it is the only place within ares and curl where such a type would be used; 
also it broke many autobuilds. We should probably introduce an ares_port_t if we want to use a type here.

0606b792f0 - Timo Teras changed the reason code used in the resolve callback done when 
ares_cancel() is used, to be ARES_ECANCELLED instead of ARES_ETIMEOUT to
  better allow the callback to know what's happening.

a450efb483 Intentionally avoid checking if the address of SystemFunction036, a.k.a. 
RtlGenRandom, has been located or not. This function is only available on
WinXP and later. When unavailable c-ares uses portable rand() function.

084447e414 - Provide in external interface preprocessor symbol definitions for 
CARES_HAVE_ARES_LIBRARY_INIT and CARES_HAVE_ARES_LIBRARY_CLEANUP
  to ease the use of new capabilities.

29b6a732f3 - ares.h no longer uses the HAVE_STRUCT_IN6_ADDR define check, but instead it 
now declares the private struct ares_in6_addr for all systems instead of
  relying on one possibly not present in the system.

resolves a host name from the given file, using the regular hosts syntax.

3e3d10824f - Carlo Contavalli added support for the glibc "rotate" option, as documented 
in man resolv.conf:

  causes round robin selection of nameservers from among those listed.  This
  has the effect of spreading the query load among all listed servers, rather
  than having all clients try the first listed server first every time.

  You can enable it with ARES_OPT_ROTATE

670273968c added ares_process_fd() to allow applications to ask for processing on 
specific sockets and thus avoiding select() and associated functions/macros.
This function will be used by upcoming libcurl releases for this very
reason. It also made me export the ares_socket_t type in the public ares.h
header file, since ares_process_fd() uses that type for two of the arguments.

dd06c60ada Nick Mathewson added the ARES_OPT_SOCK_STATE_CB option that when set makes 
c-ares call a callback on socket state changes. A better way than the
ares_getsock() to get full control over the socket state.
