Only call eina_threads_shutdown when thread are dead and not before.
Release and destroy thread lock before calling evas_async_events_process
as you should never have a lock taken in the main loop when calling it.

etc. etc. in corner-cases. it also re-factors the image cache code to
be much more manageable and understandable with cache/list management
doing the right thing in the internal calls.

for client apps that tried to be efficient with preloads to adapt
when the preloaded data is taken away from them. this allows it.
missing callback api bug fix.

(scalecaches) are flushed which can cause a hang until all data is
"loaded back in" again. it's a bit of a doosey actually and so isn't
fixed here.

Use EINA_INLIST_CONTAINER_GET instead of cast to
(Evas_Preload_Pthread_Worker*) to get eina_inlist_remove's return.
This works even if the first field of Evas_Preload_Pthread_Worker is no
longer a EINA_INLIST

There is no meaning in negative values for image loading, marking as
dirty or size, so image internals (cache, entry) were changed to
unsigned, reducing possible errors, particularly with overflow.
engines were converted to the new way, but any 3rd party modules will
still work as they should be using values >= 0 only anyway.
please review.
new cases introduced by "comparison between signed and unsigned" were
fixed in the modules that used cache_entry or Image_Entry dimensions.

As we're heading for a release we better remove as much errors as
possible and as the first step I'm removing warnings due unused
parameters, variables and functions. These tend to pollute real errors
spotted by -Wall and clang/llvm.
This does not fixes all, just the clear that could be set to
__UNUSED__, particularly to do (and I'd like some help from the
authors):
* src/lib/engines/common/evas_font_{draw,query}.c (tasn):
intl_props is just used while doing BIDI, but also used in other
#ifdef blocks :-/
* evas_map_* (raster):
huge amount of warnings, code is quite confusing and thus I'm not
touching it. I have no idea whenever the commented blocks or extra
parameters are intended to be used or no.
* src/modules/engines/fbevas_fb_main.c (raster?):
is fb_setvt() to be used? If not do you mind removing it?
* src/modules/engines/gl_{common,x11} (raster):
huge amount of warnings, code is quite nested and full of #ifdefs
that does not help to give a clear picture of what's going on.
* src/bin/evas_cserve_main.c (raster):
I could have ignored most of the errors, but is the code correct? I
mean, there is no unload of images being applied. If you confirm
none of those warnings are harmful I can flag them as unused.
* src/lib/engines/common_8 (dottedmag):
lots of unused functions that were acquired from common_16, they
are unused and if they will not, then they should be removed.

Assert cache->usage never becomes negative as was occurring before the
fix in r52149.
Just in time, the fix in r52149 was made by Ulisses, not me.
SVN revision: 52190
Memory usage was not accounted right because
cache->func.mem_size_get(ie) returns 0 when called after
cache->func.destructor(ie). Thus the total memory used, kept on
cache->usage, is never decremented in _evas_cache_image_remove_activ()
This implies that cache->usage will keep growing and eventually it will
overflow, becoming negative. So evas_cache_image_flush() will not do its
job because cache->limit (assumed to be positive) will not be less than
cache->usage anymore. So the total memory allocated will start to grow
and the limit won't be respected.
Strictly speaking, it's not a leak, since all the memory will be
eventually freed when evas shutdown is called, but the program might be
killed by over allocating memory. This is caught by valgrind with the
massif tool. The graphic below shows that in the end a huge memory amount
is allocated. This is the moment when cache->usage became negative.

This patch is a one line fix, which swaps the calls to
_evas_cache_image_remove_activ() and cache->func.destructor() making
cache->limit to be respected.
SVN revision: 52149
Lowering priority was wrong. Some bugs:
1) You don't lower the priority by setting the scheduler policy to some
of the real-time ones (SCHED_RR or SCHER_FIFO). If you do so, you are
actually increasing the priority of the workers and your main thread
you be preempted and stalled until the workers complete their job.
Fortunately this will only happen if your programming is running as
root, as normal users (without CAP_SYS_NICE) are unable to set
priority to real-time values.
2) setpriority() and getpriority() are not part of pthread and you can't
use the id returned by pthread. Manpage explicitly says so on
pthread_self(3):
"The thread ID returned by pthread_self() is not the same thing as the
kernel thread ID returned by a call to gettid(2)."
Since glibc does not have a gettid, here we are using
syscall(SYS_gettid)
This patch was tested with the program below. Compile and run:
$ gcc p_hello2.c -o p_hello2 -lpthread
$ ./p_hello2 10
You'll see that the main thread remains with its priority and threads
created by the main thread change their own niceness.
#include <errno.h>
#include <pthread.h>
#include <sched.h>
#include <stdio.h>
#include <stdlib.h>
#include <sys/resource.h>
#include <sys/syscall.h>
#include <sys/time.h>
#include <sys/types.h>
/* Lower priority of current thread.
*
* It's used by worker threads so they use up "bg cpu" as it was really intended
* to work. If current thread is running with real-time priority, we decrease
* our priority by 5. This is done in a portable way. Otherwise we are
* running with SCHED_OTHER policy and there's no portable way to set the nice
* level on current thread. In Linux, it does work and it's the only one that is
* implemented.
