Introduces the following routines to provide safe access to memory: _mem_probe() _mem_safe_read() _mem_safe_write() _mem_safe_write_to_text_section() Those routines will return an error if the memory is not accessible rather than potentially crash. This implementation is based on the image's boundaries; thus it allows read/write access to the data/bss/init sections and read access only to the text/rodata sections. All other memory is considered invalid, even if addressable. This includes the leftover from the RAM at the end of the image, since there is no support for using it (e.g. there is no dynamic allocator).
