Gustavo Sverzut Barbieri 9e80a086f6 Add and use eina_stringshare_ref().
This is a faster "add", if we know we're using a shared string we know
the node without any need to search it, just increment reference and
exit.

Gustavo Sverzut Barbieri a39edb7baa Do not pad node on 64bits.
Instead of padding node we should always refer to offset of str[]
inside node, that way we save some bytes and work properly.

Gustavo Sverzut Barbieri f22f587bab Fix stringshare on 64bits platforms.
sizeof(Eina_Stringshare_Node) is now 24 bytes on 64bits platforms, but
str[] was pointing to before that, to the 20th byte, causing out of
bounds access.

Adding the padding will cause str[] to use the correct position. It
wastes 4 more bytes, like pre-optimizations, but it's just on big
machines.

Gustavo Sverzut Barbieri 1119bfebc1 improve readability: avoid macros inside our code
mixing #ifdef'ed blocks inside code is bad, can lead to warnings if
some variables are not used and it's a pain to read.

instead, just define functions and always call them, choose their
implementation based on the ifdef macros. I opted to have 2
declarations, but one can go like other parts and #ifdef around the
function contents as well.

Gustavo Sverzut Barbieri 2569094023 Code refactor and cleanup of eina_stringshare_add().
Cases are now handled in separate, doing less useless steps and easier
to understand since 3 cases are now distinct.

Gustavo Sverzut Barbieri 96adb8e1f0 save a byte per stringshare node.
we don't need to use 'begin' flag (that takes a byte) just to see if
we're in the same memory block as the head, just do a pointer math.

Gustavo Sverzut Barbieri 0b1e2fa0dc reduce the popuplation_group size.
we just have special case for up to 3 letters, everything else is
regular population.

Gustavo Sverzut Barbieri 3cd98b547a stringshare_del optimization.
trade off safety by speed, we will always assume str was previously
shared, like evas_stringshare_del() did and we can know with zero-cost
the number of references and can avoid strlen() too.

When references drop to zero we still have to do the hash, access the
bucket and then lookup the Red-Black tree, then walk the list of
nodes, but avoiding so would use more memory, unacceptable at this
point.

Gustavo Sverzut Barbieri 24ee564949 Cheap way to get strlen of a shared string.
it's not safe, but it's faster and can help for large strings, maximum
cost is 4 comparisons plus one pointer access.

Gustavo Sverzut Barbieri c311dd99a2 stringshare: special case for small (2-3 letters).
This should reduce overhead and give a bit speedup as well, let's test
with e17 real data and see how it goes.

Cedric BAIL 1582d52c3c New stringshare implementation.
We use 256 buckets with a rbtree per bucket. The key of rbtree is the hash
on 12bits and each node of the rbtree have a list of string.

Thanks to Gustavo and Vincent for their help.
