reinstate NULL cast by request, where the NULL was being passed as a vararg

NULL does not need a cast

Fix up still more casts; use NULL instead of (char *)0.

Remove more silly casts.

Use the right type for the malloc wrapper function, and don't cast the
return value.

(XXX: Except for a pile of allocation macros that produce typed pointer
results; there the typechecking of the result assignment is more valuable
than the warning if the alloc function isn't declared properly. These
macros should go away.)

<sys/wait.h> is standard, so just use it instead of fiddling about with
ifdefs for long-dead systems. While here, remove union wait.

Correctly print variables as strings, not as format string.

Userland now builds and uses terminfo instead of termcap.

Make mostly gcc -W clean, and other cleanup:
Use const.
Add __noreturn__ attributes.
Add a __format__ attribute.
Add __unused__ attributes.
Use symbolic constants for open() and lseek().
Declare types of all function parameters; convert some function
definitions to ISO C form.
Ensure standard file descriptors are open on startup.
Check for errors writing output of makedefs.
Avoid duplicate definitions of variables.
