I was replicating this code in many places, it should go into eina itself.
It's the right way to change strings that you don't know are
stringshared before, since it will first add a reference and then
remove, making it impossible to have references to go 0 and string
being released before adding new references, fixing the following
possible problem:
x = eina_stringshare_add("x");
replace(x, x);
then:
incorrect_replace(const char **b, const char *a) {
eina_stringshare_del(*b); /* reference gets to 0 */
eina_stringshare_add(a); /* BUG!!! */
*b = a;
}

* docs: be clear if it's a copy or in-place.
* clone: add some apis to create a copy while operates, sort should
do the same.
* reversed iterator: new call to walk the list reversed, will make
life easier in some cases.

EINA_ITERATOR_FOREACH() and EINA_ACCESSOR_FOREACH() are new macros to
help us forget about nasty C details (like cast to (void **)).
Document most iterators and accessors.
All iterators now set EINA_ERROR_OUT_OF_MEMORY if it's the case.
SVN revision: 39267
now EINA_INLIST_GET(bla)->next will work, before it was like
&bla->__in_list->next
which is wrong, since __in_list is not a pointer, rather the memory itself.

safety checks will report null pointers and other error conditions on
public api's and can be disabled by compile time check.
note that in order to have these checks working we need to make
EINA_ARG_NONNULL() void, otherwise GCC can remove these checks since
they're known to be false.
This commit also make two minor changes:
* list and hash accessors and iterators are created even for empty
entities. This is correct in my point of view since NULL should
indicate error. Having these in were an optimziation, but not
worth it, these are not the most common case and hitting this path
is not of much cost.
* unmarked some parameters as nonnull, mainly on list and inlist.

this should help with optimizations and code correctness, please see
"info gcc" for detailed explanation on these.
if you experience some functions not working as expected, please
double check if they're not marked with EINA_PURE or EINA_CONST, maybe
I misused them. Remove the macro and try again.
brief explanation:
* EINA_WARN_UNUSED_RESULT: if you forgot to use the return of some
function, it will emit a warning (and -Werror will make it an
error). This way it will be harder to miss the attribution
"l = eina_list_append(l, v)".
* EINA_ARG_NONNULL(index, index...): if you give it an explicit NULL
argument, or some tool (ie: clang) finds it could get a NULL but
this is not accepted by API, then a warning will be emitted. This
will help those that still use eina_hash_add() as if it is
evas_hash_add().
* EINA_MALLOC: any non-NULL pointer it returns cannot alias any other
pointer valid when function returns.
* EINA_PURE: function have no effects other than the return and this
return just depend on parameters and/or globals. You might call
this function in a loop a thousand times and it will return the
same value, thus you may move this function outside the loop and
remove it.
* EINA_CONST: stricter version of EINA_PURE, it will not check for
global parameters, that is, you cannot consider pointer
arguments. Use it for math things like "int sqrt(int)".
* EINA_PRINTF(fmt, arg): will check format parameter specified in
position "fmt" and passed arguments starting at position "arg", it
will check for things like giving integers where short or strings
were expected.
* EINA_SCANF(fmt, arg): similar to eina_printf().
* EINA_FORMAT(fmt): for use with things like dgettext(), it will get
a printf-like format string and modifies it.
Please review and test it with your software, make sure you make clean
before you install the new version so it has any effect.
If you find some functions are missing EINA_WARN_UNUSED_RESULT and
EINA_ARG_NONNULL or others, please add them.

* evas: if we automatically destroy hash, check for NULL before
handling it to eina api, which expect elements to be created with
eina_hash_new() and thus will fail on NULL.
* eina: add magic checking for eina_hash and eina_hash_iterator, this will
help spot when NULL is used.
* eina_hash_foreach: do not try to create the iterator if hash is NULL.
