Apply badzero.cocci, badnull.coci and badnull2.cocci
This should convert all cases where there's a comparison to NULL to simpler
forms. This patch applies the following transformations:
code before patch ||code after patch
===============================================================
return a == NULL; return !a;
return a != NULL; return !!a;
func(a == NULL); func(!a);
func(a != NULL); func(!!a);
b = a == NULL; b = !a;
b = a != NULL; b = !!a;
b = a == NULL ? c : d; b = !a ? c : d;
b = a != NULL ? c : d; b = a ? c : d;
other cases:
a == NULL !a
a != NULL a

but there were no docs for hash tables because k-s and cedric were busy writing new functions for hash tables. so rasterman again said "let there be docs for hash tables! really guys, I mean it this time!"
and this time there were docs, but these docs were incomplete and in some places vague and misleading.
these docs frustrated little discomfitor, who had just healed up after learning to ride his edje bicycle and was just starting to read. so he read all that he could, and then he started to write. he wrote his little heart out until finally there were more docs for hash tables like the rasterman had wanted.
then he went and got ice cream.
The End.

Being able to indivually initialize individual modules was initially
"good", but at end it's putting complexities on users that would try
to "optimize" by doing just what they used, but in the end most people
would get them wrong, users would have to do lots of code and etc. At
the end it does not worth.
Most module init just register handful errors and log domains, so are
cheap. The exception is mempool users, that would dlopen() stuff, but
people that are concerned (embedded) can just compile those statically
in eina.
Since at the end any real application would use most of modules, we
actually end saving lots of function calls that would do nothing other
than increment a global counter.
I also did the init/shutdown use an array, making it easier to
maintain. The inital dependencies were analysed by a script I wrote, I
hope it's all right.
Please fix any breakages you find!

All these individual init functions are getting messy, some modules
lack them and it's easy to get inconsistent. Safety check needs error
and log, but these need safety checks as well, some modules (lalloc,
rbtree and others) use safety checks but provide no _init().
I want to know if we really gain something to init individual
modules. It should not be that expensive as init should not allocate
heavy resources and the recommendation is to call eina_init() so most
users will do that anyway.
If people agree I'll unmark all *_init() as EAPI and make them private
to eina lib.

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
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.
SVN revision: 37982
By using simpler functions for hash element deletion we can avoid the
hack to shut up GCC warking about hash_num not being used. As these
simple functions are more often needed than the catch-all, expose them
as well.
