Never pass char or short args to functions.  This saves 64 bytes of
recently introduced bloat in just 2 calls to biosread(), although
very little in calls to putc() and serial_putc().  Gcc produces
amazingly bad code for unnecessary conversions.  E.g., if it has
`int x' in register %edx and wants to pass a char, then it could
simply push %edx and access only one byte in the callee.  Instead,
it sometimes unnecessarily spills %edx; it always sign extends
%edx and pushes the result.

Remove useless `extern' in function prototypes.

Remove unused declaration of `end'.

Declare pbzero() and pcpy() like the library bzero and bcopy().

Declare printf() properly.
