added calls to "ptraced(pid)" and "unptraced(pid)" to make
pwait (in library.c) ignore spurious returns from wait -- this caused
a rather annoying bug to occur when doing a "sh" command

upped the maximum number of arguments on a command line to 100

now computes source position for a core dump so that things such as
pc are set appropriately

cont now takes an argument which is the signal that is passed
to the debuggee, and stepping in the main execution loop is now considerably
more efficient as it only single-steps to the next source

more efficient as it only single-steps to the next source line if the
situation calls for it

changed execvp to execv

now saves/restores process' tty state before/after execution

changed error handling for illegal addresses

now uses vfork instead for fork, also has central routine
