kern: Improve assertions and panics.

* kern/assert.h (Assert): Add function argument.
(assert): Supply function argument.
* kern/debug.c (Assert): Add function argument.  Unify message format.
(panic): Rename to 'Panic', add location information.
* kern/debug.h (panic): Rename, and add a macro version that supplies
the location.
* linux/dev/include/linux/kernel.h: Use the new panic macro.
