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.
