api: Allow injection of user-specified malloc/free functions
...
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

ares_gethostbyname: don't leak valid-but-empty hostent
...
If an AF_UNSPEC query gets a valid response to its AAAA query,
but which has no IPv6 addresses in it, then the code chains on to
a A record query. However, the hostent from the AAAA response
was being leaked along the way (because it gets replaced before
the follow-on end_hquery() invocation).

host_callback: Fall back to AF_INET on searching with AF_UNSPEC
...
Previously, when an ares_gethostbyname() searched with AF_UNSPEC and the
first AF_INET6 call only returned CNAMEs, the host_callback never
retried AF_INET.
This patch makes sure than on ARES_SUCCESS, the result of AF_INET6 is
taken as authoritative only if the result contains some addresses.

- Phil Blundell: If you ask ares_gethostbyname() to do an AF_INET6 lookup and
...
the target host has only A records, it automatically falls back to an
AF_INET lookup and gives you the A results. However, if the target host has
a CNAME record, this behaviour is defeated since the original query does
return some data even though ares_parse_aaa_reply() doesn't consider it
relevant. Here's a small patch to make it behave the same with and without
the CNAME.
