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
Add comments for the benefit of the lcov tool, marking
lines that cannot be hit. Typically these are fall-back
protection arms that are already covered by earlier checks,
and so it's not worth taking out the unhittable code (in case
someone changes the code between the two places in future).
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.
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.
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.
that is now used by the ares_parse_*_reply() functions instead of the
ares_expand_name() simply to easier return ARES_EBADRESP for the cases where
the name expansion fails as in responses that really isn't expected.
