[PATCH] introduce compiletime loglevel

[Sascha Hauer]

This makes the loglevel configurable at compile time. This allows
to optimize away the lesser important messages from the binary.

Also added is a pr_fmt macro as in the kernel which allows to
define a file specific prefix to the pr_* messages.

As a positive side effect pr_debug() and debug() is no longer
optimized away by the preprocessor but by gcc. This way we have
nice warnings for all the wrong debug calls in the code, so this
series also cleans them up and it makes it harder to introduce
new wrong debug calls.
