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. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@27902 a1c6a512-1295-4272-9138-f99709370657
