e94eea9538 Invalidate the CPU cache after clearing bss, to make sure that bss variables that are used via non-cached aliases don't read garbage.
This fixes FS#11653 for me

da16248e47 Plugins: modify IRAM copying code
Move to plugin_crt0.c, plugins don't need PLUGIN_IRAM_* macros anymore
IRAM is no longered zeroed before copying (as it is at the same address
than BSS) -> Fix FS#11581
Use cpucache_invalidate() (and not cpucache_flush), needed for self-modifying code on cached IRAM

194174a371 2nd try: Introduce a small api for loading code (codecs,plugins) from disk/memory.
It's a used by codec/plugin loading and vastly reduces code duplication. It's also a step forward in getting rid of libuisimulator in the application ports.

Apparently sh needs linker symbols prefixed with _ even if they're referenced without from C code.

I don't understand the build error at all, plugin_bss_start is clearly defined in plugin.lds

cae4ae2c71 Second try: Introduce plugin_crt0.c that every plugin links.
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.
