array, list, struct and others set() now copies the values. These
values can be created by user, in this case string is just a stack
object and not a real eina_stringshare.
To cope with it, add the string instead of referencing it. Bit slower,
but nicer behavior.

I did a bad decision to steal memory for Array, List, Hash and Struct
types, it was nice to not have to copy it internally, but breaks when
one needs to set a new value that was set elsewhere. What did not
happen with string, integers and other basic types.
This was exposed by Raphael Kubo using eina_model_property_set() with
complex types (Array, List and Hash) and it was not possible to
correctly set such properties.
Now it's all set, but the behavior changed and the memory is not
stolen and released anymore. Test eina_test_value.c was changed to
reflect it.

if user get and then set the same value, we should not crash and this
may happen with previous code as the old
string/array/value/list... were released, then you ended with the
released memory still being pointed.

1. consider case where the struct was not set for flush and others;
2. flush previous struct on pset;
3. setup the new struct members memory on pset;
4. always use ops->alloc and ops->free if they are provided;

efficient storage with named access, can specify compare, alloc, free
and other operations for even better management.
no changelog/news as this is under eina_value, all new for 1.2 release.
SVN revision: 67155
Nice type that even supports configurable operations such as compare,
free, copy and to_string.
the usual is also supported: provide no ops (operations) and memory
will be left untouched.
nice feature to dump as string :-)

Similar to list and array, but takes string keys instead of position.
It can convert to string, I've added tests for it, but hash algorithm
changes may break the simple comparison I did... and I don't want to
parse the string to be more accurate.
SVN revision: 67103
Similar to array, but less efficient as uses list nodes. If possible
values are stored on list->data itself, otherwise they are allocated
and the pointer goes as list->data.
SVN revision: 67096
Should be more portable and work with C++.
NOTE: I still see an aliasing break in eina_value_pset, but wasn't
able to figure how to solve it.

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.
