call eina_threads_init() to enable this if you have pthread rwlock support (posix 2001)
note some function prototypes have lost const on array params to allow locking
WARNING: you should NOT call eina_threads_shutdown unless you are positive that you will not use any arrays which were created while threadsafe mode were enabled, and vice versa. Failing to adhere to this warning WILL result in either deadlocks or memory leaks.

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.

It's pointless to be able to change magic number string after it's
created, so let's avoid walking the existing list and just remove
places where strings were being duplicated (list/array both inited
magic strings for accessor/iterators).
Also an optimization, register using an array and sort it before
searching. Sort will just happen when array was changed, and this is
just done when eina_magic_string_get() is called.

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!

Sparse Matrix was implemented and tested by Rafael Antognolli and
myself in order to implement optimized large sparse matrix walk in
some products, one of them WebKit-EFL optimizations.
We have done extensive tests, with good code coverage. Similar to
lists/inlists, we keep pointer to last known element and similar to
iterators we keep reference to last accessed row and cell inside
rows. This allows fast sequential access (for i... for j... m[i,j]),
that is our most common usage case.
Rows are kept in a list, with cells inside that row as another
list. It's not similar to most book implementations where cells keep
reference to their sibling cells in other rows as well, we opted to
not do that to save some pointers and make algorithms simpler, still
do great for our use case.
This code was developed on behalf of our client, that wants to remain
unnamed so far. Thanks client ;-)

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.
