Subject: kern/printf: do not serialize printf and co

A lot of code assumes that printf is re-entrant, e.g. the pagination
code in the debugger, or any use of assert inside the console driver.

* kern/printf.c: Drop the lock serializing calls to `_doprnt'.
(printf_init): Remove function.
* kern/printf.h (printf_init): Remove declaration.
* kern/startup.c (setup_main): Remove call to `printf_init'.
