C library for commands execution

s2argv converts a command string into an argv array for execv, execvp, execvpe. execs is like execv taking a string instead of an argv. Similarly execsp and execspe are the counterpart of execvp and execvpe, respectively, using command strings. coprocv, coprocvp, coprocvpe, coprocs, coprocsp execute a command in coprocessing mode. The following functions all work without using a shell: esystem, system_eexecsp execute a command with its arguments from a string. popen_nosh, popen_execsp and pclose_nosh pipe stream to or from a process. system_nosh executes a command with its arguments from a string.
