It handles exit() properly, calling the handler also when the plugin returns
normally (also make 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 rb->default_event_handler_ex() 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.

struct plugin_api *rb is declared in PLUGIN_HEADER, and pointed to by
__header.api
the loader uses this pointer to initialize rb before calling entry_point
entry_point is no longer passed a pointer to the plugin API
all plugins, and pluginlib functions, are modified to refer to the
global rb
pluginlib functions which only served to copy the API pointer are
removed
