eina value is a generic value storage, it's quite efficient to space
(16 bytes) and speed (inlines for basic types).
It's basically a structure describing how to manage memory
(Eina_Value_Type), with default implementation for char, short, int,
long, int64_t (and unsigned variants), float, double, stringshare and
string.
If a type 'value_size' is smaller than 8 bytes, it's stored
inline. Otherwise a value is allocated and managed.
Most of the methods are inline, with special handling for char, short,
int... Then no extra calls are made, allowing the compiler to optimize
them.
For array of a single type it is recommend to use Eina_Value_Array, as
it will efficiently store and access members (just a char if subtype
is EINA_VALUE_TYPE_CHAR, etc).
It can copy itself, compare itself. Including arrays.
It would be nice to have something that converts between EET and this.

It is an inline array, that is, the members are actually in the
allocated buffer, as opposed to a pointer to its data.
It can be used to manage array of integers, floats or other structures
without fragmenting memory.
The lookups should be fast as memory is linear, then CPU prefetch can
kick in and bring data to cache before it's used.

A clist is an inlist with the following features:
- allows removal of items without knowing which list they are in.
- Two pointers per list item & list head

This API is what could be used by all EFL library for their exposed
type (Evas_Object, Ecore_Timer, Ecore_Animator, Eio_File, ...). The
purpose of Eina_Object is to provide an "obscure" pointer that is
infact an ID with a generation count that will never be dereferenced
directly.
This provide the benefit of always accessing a living object
with 1/256 chance to being the expected generation of it, that will
always be of the right type.
It also provide asynchronous repacking ability (still highly
inefficient, but not really hard to improve), simple inheritance
with constructor/destructor and link between object.
All this implementation is highly open for comment, idea, review,
fix and change. I didn't got the time to write a sample test right
now. Maybe will come tomorrow. Same for docs.

TODO: fix docs (but today, eina doc need some love again)
use iconv and handle encoding (can get entity-to-utf8 from evas)
description of what to do at :
http://marc.info/?l=enlightenment-devel&m=129975452006699&w=3
NOTE: this mean this API is not stable yet and will be broken soon.

This function is useful for libraries like ecore and evas that have to
set some worker threads. The first thing these threads should do is to
call this function, so the main thread might continue running without
the worker threads interrupting it too much.

Also modified Eina_Stringshare to share most of the code with the two above.
Added Magics for Eina_UStrbuf as well as for UStringshare/Binshare.

* eina_str_split() now does the minimum number of passes and
allocations. The first pass figures out the string size (strlen())
and number of delimiters, so we can allocate the exact number of
elements in array. The second repeats the loop copying elements to
string and also setting them to the result array.
* eina_str_split_full() is a variation of eina_str_split() that
returns also the number of elements in array, in the case you need
to pre-allocate another array to copy.
* eina_strlen_bounded() is introduced to limit strlen() results, this
is used in has_prefix and has_suffix, but possibly other use cases
where string must be of a maximum size as we don't do useless
iterations;

This new iterator receives a rectangle as argument and tile_w X tile_h sized
tile, and slices the rectangle iterating over it on each iteration.
SVN revision: 42427
* eina_error might be kept for error messages and codes, but it's logging API
will be deprecated. For now, it's been kept for not breaking others code and
for a smoother transition.
* Added test for new logging API, also demonstrates usage.

<dieb_> weird, undefined refernce to eina_cpu_count
<raster> you have no cpus!
<dieb_> dammit!
<Sachiel> try eina_hamster_count
<dieb_> lo
<raster> oh god
<raster> now u did it
<raster> i have to add that
<dieb_> heheheh

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;
}

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.

The current implementation choose to move the node allocation outside of eina
control like eina_inlist. They currently have the same memory footprint as
eina_inlist and the implementation of insertion and lookup are iterative
making it quite fast. This should make them a good competitor of eina_inlist
for eina_hash and eina_stringshare.
