Introduce logging to disk feature into rockbox.
Logs information, errors, etc to disk using the register_storage_idle_func
mechanism to write to the disk when available. Currently, this is disabled
in normal builds, but can be enabled by adding ROCKBOX_HAS_LOGDISKF to the
config file. By default, it uses a 2KB buffer and drops text if the buffer
overflows.
The system includes a simple warning level mechanism that can be used to by
default exclude non-serious errors from logging on release builds.
