Images and Files can be discovered by the client scanner before they
are valid (aka. loaded or opened). We want clients to ignore all
shared objects that are not ready yet, as they are in an undefined
state (values and memory might be invalid).
Shared string indexes are not repacked, since they live in a
memory pool (where the indexes can be reused).
So, the index in the table is equal to their ID. Add initial
test to check if the item at index n has the ID n.
- Create one Glyph_Data array per Font_Entry
- Copy Font_Source descriptors in shared array
- Copy font entries in shared index
- Send font index path over socket
- Merge Font_Source and Font_Data in shared memory
- Send font index path on client connect
- Repack font index after free
- Pass font shm name to clients
Read Image descriptors from the shared arrays
But, accessing the shared index can be a bit expensive, so
try to read from the socket before scanning the index,
without blocking.
- Send paths to all connected clients
- Send paths upon connection from a new client
- Client side:
- Fast find opened images
- Fast find loaded images
- Optimize load by skipping socket wait
Also, remap indexes when needed (file size changed)
When index file grows, the clients are not notified, so they
must constantly check that their mapping matches the current array
size.
- Move required struct definitions to common evas_cs2.h
- Open/close shm and map arrays to memory
Pretty stupid for now as it will close & reopen the shm files
even when unchanged.
- Check shm size and array header consistency
- Implement message send
- Send messages from server when calling repack()
When opening an image, OPEN and SETOPTS were always sent
consecutively. Merging these two messages may improve the
performance a bit (not measured), but also simplify the
whole thing.
Note: cserve2 debug tools have not been fixed yet.
Most of the time, the SETOPT message is sent only
to carry 0 data. Let's add a flag to the OPEN message to
avoid useless socket calls.
Server-side: implement with message faking.
Also, fix image ID logic on client side:
- alloc data entry asap,
- assign image_id during call to OPEN

In case of EACCESS, there is no point trying forever
In case of EINTR (interrupt), we can consider for now
that any signal will prevent the use of cserve2.
If we don't do that, Ctrl+C simply won't work :)
It seems some images are fully loaded even when we request
only preload. The load handler will take care of both cases anyway.

I've tested make -j 3 install and it works nicely
I've tested expedite with software and opengl xlib,
and it works. Not tested other engines, so please
report any problems (engines or other) on the ML.
TODO: examples and tests, I'll add them later
ISSUE: Eina_Unicode size check. It indirectly depends on
eina_config.h, which is created at the end of the
configure script. So its size is always 0. I don't
know how that size is used, so I can't do a lot,
for now.
