Introduce plugin_crt0.c that every plugin links.
It handles exit() properly, calling the handler also when the plugin returns normally (also it makes exit() more standard compliant while at it). It also holds PLUGIN_HEADER, so that it doesn't need to be in each plugin anymore. To work better together with callbacks passed to rb->default_event_handler_ex introduce exit_on_usb() which will call the exit handler before showing the usb screen and exit() after it. In most cases it was passed a callback which was manually called at all other return points. This can now be done via atexit(). In future plugin_crt0.c could also handle clearing bss, initializing iram and more. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@27862 a1c6a512-1295-4272-9138-f99709370657

/* OTHER CREDITS:
 *
 * This is the normal smoothscale method, based on Imlib2's smoothscale.
 *
 * Originally I took the algorithm used in NetPBM and Qt and added MMX/3dnow
 * optimizations. It ran in about 1/2 the time as Qt. Then I ported Imlib's
 * C algorithm and it ran at about the same speed as my MMX optimized one...
 * Finally I ported Imlib's MMX version and it ran in less than half the
 * time as my MMX algorithm, (taking only a quarter of the time Qt does).
 * After further optimization it seems to run at around 1/6th.
 *
 * Changes include formatting, namespaces and other C++'ings, removal of old
 * #ifdef'ed code, and removal of unneeded border calculation code.
 *
 * Imlib2 is (C) Carsten Haitzler and various contributors. The MMX code
 * is by Willem Monsuwe <willem@stack.nl>. All other modifications are
