Thomas Martitz abdc5935be 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.

/****************************************************************************
* NOTES:
*
* mpegplayer is structured as follows:
*
* +-->Video Thread-->Video Output-->LCD
* |
* UI-->Stream Manager-->+-->Audio Thread-->PCM buffer--Audio Device
* | | | | (ref. clock)
* | | +-->Buffer Thread |
* Stream Data | | (clock intf./
* Requests | File Cache drift adj.)
* | Disk I/O
* Stream services
* (timing, etc.)
*
* Thread list:
* 1) The main thread - Handles user input, settings, basic playback control
* and USB connect.
*
* 2) Stream Manager thread - Handles playback state, events from streams
* such as when a stream is finished, stream commands, PCM state. The
* layer in which this thread run also handles arbitration of data
* requests between the streams and the disk buffer. The actual specific
* transport layer code may get moved out to support multiple container
* formats.
*
* 3) Buffer thread - Buffers data in the background, generates notifications
* to streams when their data has been buffered, and watches streams'
* progress to keep data available during playback. Handles synchronous
* random access requests when the file cache is missed.
*
* 4) Video thread (running on the COP for PortalPlayer targets) - Decodes
* the video stream and renders video frames to the LCD. Handles
* miscellaneous video tasks like frame and thumbnail printing.
*
* 5) Audio thread (running on the main CPU to maintain consistency with the
* audio FIQ hander on PP) - Decodes audio frames and places them into
* the PCM buffer for rendering by the audio device.
*
* Streams are neither aware of one another nor care about one another. All
* streams shall have their own thread (unless it is _really_ efficient to
* have a single thread handle a couple minor streams). All coordination of
* the streams is done through the stream manager. The clocking is controlled
* by and exposed by the stream manager to other streams and implemented at
* the PCM level.
*
* Notes about MPEG files:
*
* MPEG System Clock is 27MHz - i.e. 27000000 ticks/second.
*
* FPS is represented in terms of a frame period - this is always an
* integer number of 27MHz ticks.
*
* e.g. 29.97fps (30000/1001) NTSC video has an exact frame period of
* 900900 27MHz ticks.
*
* In libmpeg2, info->sequence->frame_period contains the frame_period.
*
* Working with Rockbox's 100Hz tick, the common frame rates would need
* to be as follows (1):
*
* FPS | 27Mhz | 100Hz | 44.1KHz | 48KHz
* --------|-----------------------------------------------------------
* 10* | 2700000 | 10 | 4410 | 4800
* 12* | 2250000 | 8.3333 | 3675 | 4000
* 15* | 1800000 | 6.6667 | 2940 | 3200
* 23.9760 | 1126125 | 4.170833333 | 1839.3375 | 2002
* 24 | 1125000 | 4.166667 | 1837.5 | 2000
* 25 | 1080000 | 4 | 1764 | 1920
* 29.9700 | 900900 | 3.336667 | 1471,47 | 1601.6
* 30 | 900000 | 3.333333 | 1470 | 1600
*
* *Unofficial framerates
*
* (1) But we don't really care since the audio clock is used anyway and has
* very fine resolution ;-)
