[PS2] Extend ERL library

[misfire]

I've written some code that extends the functionality of the ERL library:

- add functions to relocate an ERL at a specific memory address (ERLs are relocated at a dynamic memory address by default.)

- add ability to clear ERL bytes on unload

liberl.patch.tar.gz (apply both patches)

Here is a sample project that demonstrates how to use the new *_to_addr functions. I find them very useful - if you know what you're doing. ;)

--------------

Besides, this is a small (unrelated) fix that allows debug.h and hwbp.h to be included at the same time:

hwbp.h.patch.gz

Nice additions :)

So, could anybody commit the patches?

Done, thanks.
