- For V2 and FM Recorders, don't recommend bootloader upgrade
  due to FS#12426 BootBox bugs.
- When rockbox.ucl can't fit and the bootloader is old, the
  bootloader needs to be upgraded.
- When RomBox start address differs, the bootloader is
  not compatible with RomBox.

Rather use the Makefile to specify which files must be built
Fix color builds with test plugins enabled (test_scanrate gave an empty
.o file)

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.

Too much errors and no time to fix them now.

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
