misc/threads.c: Implement vlc_threads_error(), that is called when an error is encountered in the threading system. The whole point of this is to ease debugging of such situation, by exposing a nice symbol on which we can break. (This costs nearly nothing).

Otherwise, it'll screw up completely when we add vlc_cond_timedwait

They should not be used by plugins. And in fact, they are not.

The idea is that a given error should be reported only once to the user.
At the moment, for example, we can get:
- "no suitable access module" (printed by module_Need)
 - "unable to create access" (printed by input/access)
 - "unable to open stream" (printed by input/input)
 - ...

The facilities provided here are:
* msg_StackSet( code, message ) : "throw" a new error
* msg_StackAdd( message ) : Append a message allowing to trace the message
* msg_StackMsg() : Retrieve the message

So, in the previous example, module_Need would msg_StackSet( code, "no
suitable access module"), then input/input would add "unable to create
access" and finally, input/input can print the "unable to open stream:
unable to create access: no suitable module" message.

The three functions are context-free, you don't need a vlc_object, so
that we can add verbose error reporting everywhere.

Fix Win32 implementation

* libvlc sources and plugins now define __LIBVLC__ and headers exported to
  plugins (ie, include/vlc_*.h) check for this
* libvlc sources use the value of the "libvlc" component in vlc-config instead
  of vlc
* Apply flags directly to "libvlc" in configure.ac - might temporarily break win32 :)

* Some cast magic to get around a gazillion of warnings during the OSX build. If your OS has similiar warnings, feel free to add yourself to the define list :D. Solution thanks to Sam.

../include/vlc_threads_funcs.h:501: warning: cast from function call of type 'pthread_t' to non-matching type 'int'

- Fix threading qualifier warnings

(da big courmischage)

  It wasn't implemented for all systems anyway, and isn't used anymore.
  (Terminates #23)

 + *threads*, src/libvlc.h:
   test HAVE_KERNEL_SCHEDULER_H before PTHREAD_COND_T_IN_PTHREAD_H
   for now because Zeta now has a pthread implementation but it's doesn't
   seem to be (enough) POSIX compliant atm.

* src/misc/threads.c, include/vlc_threads_funcs.h: another bunch of fixes
   for the GNU-pth implementation.

* src/misc/threads.c, include/vlc_threads_funcs.h: fixed gnu-pth thread
   implementation and fixed an initialization bug in libvlc.

    checks as printf. Only works with gcc 3.2 it seems.

thread.

    WIN32 isn't always defined under WinCE, but might be. Grmbl.
  * ./include/*: changed a few u* and s* to uint*_t and int*_t.
