Overhaul the fork(), exec() code. Put all the common handling that
takes place in the child process in a function ProcExec(). Make sure,
that the child does not call malloc() or other potential dangerous
functions (there are still calls to Punt() in the error case that
should go away). Allocate the argv string via malloc to overcome
the non-constness bug of the execvp prototype. Change the handling of
shell meta-characters and move the builtin list near the list of shell
builtins. Both of these lists should actuall be configurable by the .SHELL
target since they depend on the shell used.
