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

Jakub Hrozek modified ares_parse_srv_reply() and ares_parse_txt_reply() API

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().

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.

Replace 'uint16_t' with 'u_int16_t' since the latter is used in ares.h.
