*client->server renamed client->host_server to clarify ambiguity
*ecore_con_ssl_client_prepare.* killed off because it was useless and wrong
*openssl generates only one SSL_CTX per server now instead of a new one for each client, which is broken/unnecessary/wasteful
**as a result, certificate loading is now only done once
**additionally this will save a very large amount of memory and avoid unnecessary/broken refcounting
*ecore_con_ssl_server_prepare.* rewritten to actually be useful instead of just a lazy way to null pointers
**all SSL_CTX code now goes here^
*some formatting fixes
*internal function renames

Essentially the problem is this: For drag and drop Ecore currently handles the
position update calls. But usually the application wants to display some user
feedback - a window to display the drag selection for instance.
Now the way e17 does it is grab the mouse cursor movements and track them
itself. However ecore is already doing this, it's already walking window
trees, calculating real positions, _and_ sending them in an X client message.
So it seems rather silly to duplicate the code in the user app to get the same
info.
We could possibly have added a new event, but then we need to deal the fact
the position update may arrive _After_ the item has been dropped. Hilarity
ensures[1].
This callback is meant for purely the selection owner of the drag to use, so
it is a callback set, not an add.
[1] Segfaults probably. Nothing funnier.

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.
